Gold Alligators

March 9th, 2013 [print] No comments

I sold off my Avid BB7 (mtn) brakeset, so I can replace it with a more appropriate CX set-up.  Since the Shimano CX-75 calipers I have on order don’t come with discs, I got the prettiest ones I could find:

I figured I’d try out a couple different models, and see which works best.  The titanium nitrite coating will actually wear off pretty quickly at the braking surface, which is good, since it’s used as a low-friction coating.  It’s the same stuff on my KMC chains.

I’m hoping to get my bike back together by the time the gravel roads dry up.

Guess who’s stuck inside?

February 27th, 2013 [print] 2 comments

The mid-West got hit with 11" of snow late last week, and another 10" this week.  Since I’m not ballsy (or crazy) enough to try to ride my bike in those conditions, I’ve been making up for it by shoveling snow.  250ft of sidewalk, just to have something to do and burn some calories.

And in the mean time, I’m still getting my dropbar 26er just how I like it.

I plan on doing some long distance gravel training as soon as everything dries out enough, so I swapped to my trusty Carbon Cycles rigid carbon fork.  That dropped weight by a couple pounds.  I also sold my SRAM X.7 double crankset for an X.9 triple, then tossed the granny gear, and have it set as a double.  Why?  Well, because the X.7′s retarded 120mm BCD meant there were basically no aftermarket chainrings available, and I needed to move to a larger big ring to stop spinning out on descents.

Now it’s set up with a 48T large ring which, with the 26×1.9" tires and 11T cog, gives me roughly the same top end gearing as a CX bike running 35c tires and 46×11 gearing.  But, since the tires are larger volume than most CX tires, I can run them at a lower PSI and cruise right over chunky gravel.

I admit, it’s still a bit of a weird set-up, but it’s incredibly versatile:  it’s competitive with a CX bike, but I can toss a suspension fork and 2.35" Nevegals on it, and still go anywhere.

Changes still in the works are Shimano CX-75 brake calipers, so I can lose the Travel Agent brake adapters, and Alligator rotors.  Once I sell some of my bike parts hoard, I’ll look into replacing the fork with something else to remove close to another pound. At which point, I think I’ll finally be done.

For now.

Dropbar MTB

I promised pics, so here you go:

One thing I’ve never understood is why road and mountain bikes have different cable pull ratios for brakes.  I suppose it’s so you have to keep buying more shit.  Well, since I just bought these Avid BB7s not too long ago, I decided to keep them, and go the cheap route by using Problem Solvers Inline Travel Agents, which allow road brake levers to work with mountain bike brakes.  Yes, they’re ugly, and yes, they add a little weight.  But I wasn’t going to give Avid the satisfaction of selling me a set of Road BB7s.  Also, by keeping the current calipers, I can easily go back to using a flat bar at any time.  Honestly, though, I can’t imagine I ever will.

Brake feel is still on par with what I had before, so the Travel Agents don’t make braking feel weird, either from the main brake levers or the ‘cross levers.  In the past, I rode rim brakes with 2mm or less gap between the rim, and my brakes had very little modulation.  I loved it.  Move the index finger 2mm, and you brake gently; 3mm and you brake hard; 4mm, and you’re dead.  It was wonderful, and I’m not being sarcastic.  However, now that I’m used to brakes that have actual modulation, I quite like it and, as I said, I’m happy with the feel.

Here’s another ugly but tolerable add-on that I have to live with.  My fork has a mechanical lock-out remote that mounted to my old MTB handlebar.  However, there’s no way to fit it to a larger diameter road bar (even on the narrow section), so I had to get creative.  I ended up using a generic mount I found on eBay, which was intended to be used as a spot to mount lights.  I cut a 1.5" piece of an old Easton carbon bar that can’t be used anymore, and mounted the remote to that.  It’s still in close reach when I need it, but I though it’d look better if I could mount it directly to the handlebar.  Oh, well… compromises must be made when you’re building weird bikes.

Here’s another look at the remote mount, as well as my super tidy cables.

So, what was the point in this ridiculous set-up?  Primarily comfort.

Coming from mountain bikes, it took me awhile to adapt to road drop bars.  But, once I did, I began to love the race position they put me in, especially in the drops (I spend about 99% of my time in the drops, rarely using the hoods on my road bike).  I know, most people don’t think a race position is anything near comfortable, but for me it is.  I love that forward position, staring not at nature, buildings, birds in the trees, but at the road directly ahead of me, crouched like a cheetah ready to pounce.  To me, it’s Lay-Z-Boy comfortable for hours on end.

I’d been riding my road bike almost exclusively for about a year, when I signed up for that sadistic Cedar Cross race last Spring.  Since I didn’t have a real ‘cross bike (my Scrambler probably would have worked, but the widest tires I could fit were 32c, and I didn’t know if that’d be enough on the singletrack), I took my hardtail.  As natural as it was to ride, using a flat bar was no longer comfortable on the gravel roads or Katy Trail, and using the bar-ends didn’t help much.  All I could think for the final 30 miserable miles was, "Man, too bad this bike doesn’t have drop bars; then it’d be perfect!"

So, now the day has come–my MTB has drops.  Reach and drop are identical to my main road bike, and I feel totally at home riding it for the first time in a long time.  I haven’t had much time to ride singletrack, yet, but the little bit that I have done has gone well.  For steeper descents, I can use the ‘cross levers and get my butt behind the saddle, and for climbing, I have my choice of drops when I have traction, or hoods when I don’t.  Oh, and when I hit a fire road or pavement, I can just lock the fork, stand up, and sprint, just like I do on my road bike.

I also discovered a side benefit of using a road bar:  it’s very narrow.  My old flat bar was 22", which is considered too narrow by today’s standards (and too wide by mine).  My road bar is only 16.5", which gives me anywhere from 5 to 10 inches extra space between trees or fence posts than other bars.

I can’t say this set-up is for everyone (or anyone), but it works for me.  Thankfully, SRAM’s Exact Actuation throughout their higher-end component lines helps make this sort of thing not only possible, but extremely easy to do.  If you like the feel of a cyclocross bike, but want some fork travel and fatter tires, maybe give it a second thought.

Winter Update

November 24th, 2012 [print] No comments

Man, I can’t believe it’s been 5 months since I’ve updated this thing.

So far, 2012 has been my highest mileage year yet, with over 6,600mi ridden so far, and a goal of 7,000mi by the end of the year.  That will totally depend on how dry it stays outside, but so far it’s looking like it might happen.

I currently have almost 8,500 miles on my cheap FM015-ISP Chinese carbon frameset, and it’s still just as much fun to ride as the day I got it.  If you’ve ever thought about buying one of these Chinese direct frames, do some research on RoadBikeReview.com and don’t hesitate buying one, even if it’s just for an off-season training bike.  Personally, if I could do it all over again, I’d go with the FM039, but only because it’s a little more aero than what I ride.

Back in August, I swapped some parts on my Scrambler and temporarily turned it into a track bike again, so I could go do some laps at Penrose Velodrome in St. Louis.  I can honestly say it’s the bumpiest paved surface I’ve ever ridden, and it’ll scare the hell out of you if you’re going over 25mph on the back corner.  But even so, I had a blast doing it, and plan on going back once the weather gets nice again.

Click for larger image

For now, I’ve set the bike back up as a singlespeed, running some 30c CX tires.  I had a lot of fun running it as a 2×10 with derailers, but since I didn’t spend as much time on it as I’d planned, I’ve decided to re-purpose some of the parts for another odd project…

That’s right, I’ve put drop bars on my 26" hardtail:

Click for larger image

I just started swapping parts last night, and it’s nowhere near done, so just accept this as a teaser pic; I’ll post more photos once it’s finished.

Ever since the Cedar Cross race last May, I’ve been wanting to set it up like this.  To be more specific, ever since around the 85mi mark of the race, I’ve been wishing I had drop bars on it.  After becoming so used to riding in drops all the time on my road bike, using a flat bar with bar ends just wasn’t the same, no matter how low I tried to get the bar.  All I could think about for those last 30 miles was how much I’d rather be in the drops, so it’s about time to just make the switch.  I think it’ll take me some time to become accustomed to drops on an MTB, and I don’t know if I’ll ever be as fast on singletrack with this set-up, but overall, it should be more fun to ride than it has been in the past.

 

SMSG MBT Race Rescheduled

October 30th, 2010 [print] No comments

After spending a lot of time getting my bike (and myself) tuned properly for the Show-Me State Games MTB race last July, rain hit, and the race was canceled.  I was pretty bummed about it, especially since I’d decided about a year before that I would race it this year.  In fact, it was just the night before the race that I was out on the trails, checking trail conditions, and seeing what changes were made by park officials to counter destruction due to heavy rains in the spring.  As I was 3/4 through with a lap, thunder hit, the skies went black, and I high-tailed it to my car, just in time for a massive storm to hit.

Anyway, the race was called off, and we were told we’d have to wait until July 2011.  A lot of racers were disappointed, though, and I guess there was a push to bring the race back.  I found out last Tuesday that it would be held today, but with no really prep time, and a bike that would need to basically be rebuilt after my rail-trail mods, I decided it wasn’t worth the effort.  Besides, who wants to race in the cold?  It would have been over 100° in July, but today it was about half that.

Oh, well.  I’ll still be waiting until next year, and by then, I’ll have a little more angst to take out on the race track.  In the mean time, I’ll get the race results posted as soon as they’re available.

Katy Trail Century

October 10th, 2010 [print] No comments

As I mentioned a few weeks back, I wanted to ride the Katy Trail in Missouri, from Jefferson City to St. Charles in a day.  At the time, it was supposed to be my second century ride, but ended up being my third, after a 60mi training ride got out of hand and turned into 100.  Anyway, I’m happy to say everything worked out, and on the 25th of September, I did the ride.

Impromptu Century

September 13th, 2010 [print] No comments

Click for larger image

In planning for my Katy Trail century across Missouri, I thought it’d be a good idea to do a 60-mile ride on Sunday.  I left for my ride equipped how I plan to be for my Jefferson City-to-St. Charles ride, just to get an idea of how my stuff would feel/perform.

My original plan was to start at the smoke stacks on MU campus in Columbia, MO, and do exactly 30 miles, then return.  Somewhere along the way, though, I decided to go ahead and ride all the way to Jefferson City.  My thinking was, it’d only be a few miles more, and as long as I’m going in that direction on a beautiful day, I might as well take it the whole way.

Prepping for a Century

September 7th, 2010 [print] No comments

As far as I’m concerned, my Katy Tail Century is a go.  But, being a bike weight-obsessed dipshit, my first thought was, how do I get my bike to its lightest before the ride?  Fortunately, I have years worth of experience in this sort of dipshittery, so I’m hard at work making my wife question marrying me eliminating weight from my Fisher Wahoo before the big day.

Getting my bike under 18.5lbs is actually easier than it sounds, since many of the parts currently on it were initially bought with light weight in mind.  Still I had to swap a few things…

My SR Suntour Epicon RLD fork weighs just shy of 4lbs, so I replaced it with the Carbon Cycles eXotic rigid fork I took off last fall.  That’s a savings of roughly 1.9lbs, and I don’t really need suspension for a flat trail anyway.

Next up, and even more importantly, was to get rid of rolling weight.  I swapped to a set of Kenda Klimax Lite tires which, together, weigh about the same as just one of my more aggressive tires alone (649g/pr).  I put in some Forte LunarLite tubes, as well.

Since I already run 1×9 gears, I decided to swap the Shimano XT 11-32 cassette for a Sram PG-970 11-23 9-speed road cassette, shaving off close to another quarter-pound.  The close gear ratios will also help keep my cadence steady as I spin my cranks for 7-8 hours.

Click for larger image

Finally, I pulled an old Easton CT2 carbon handlebar out of my parts bin.  It’s been chopped down to 20.5" and weighs 119g with end plugs, 28g less than my Titec Ti 118 bar (I told you I was being ridiculous).  I actually prefer the narrower width of the Easton bar on the long flats I’ll be riding, so it wasn’t all about taking off weight with this piece.  I normally don’t trust carbon bars for XC riding, but on the Katy, you could just about ride a bar made out of straw and not worry about overloading it.

Click for larger image

I didn’t have any foam grips laying around (I swapped back to rubber grips after having the foamies come loose a couple times), so I used some Easton road bar tape instead.  I’ve been wanting to try this out to see how it feels on a trail bike, so I figured this was a good excuse.

All told, the bike is now at 18.33lbs.  I have a Selle Italia Signo T1 triathlon saddle on the way ($26 on eBay–woot!), so that’ll add 30g back on, but it’ll be worth it to have the additional padding since I never have reason to stand up while pedaling on the Katy.

I’m also re-thinking my food and water situation for the trip.  I had planned on 100oz of water in my CamelBak, plus two 33oz bottles on the bike with Gatorade in them.  Since I’m passing through 22 towns along the way, I may take a 70oz bladder of water, and stick to just one bottle, refilling them along the way when needed.

Less weight means an easier bike to push for all those miles, and I see no sense in making it anymore difficult than it needs to be.  Colin Chapman would be so proud.

Planning My 2nd Century

September 1st, 2010 [print] No comments

I started biking in ’98, then waited some 12 years to ride my first century.  This time, though, I think I’m going to keep it to around 4 months.

Last time, I kept to the road, mashing my pedals all around my hilly city on a singlespeed.  My legs hurt, but all the time out of the saddle, standing during climbs, kept my butt from feeling too much pain.  This time, though, I’m swapping my SS road bike for a geared MTB, the roads for a rail-trail, and the hills for the flattest trail around.

Katy-Trail, MO - Click for larger image

Sometime before the end of September (I hope, but it’s dependent upon the weather), I’m going to ride the Eastern section of Missouri’s Katy Trail, from Jefferson City in the middle of the state, to St. Charles in the East (map).  Total distance is about 104mi, according to this chart, so it’ll be my longest ride to date.  I’m figuring on about 8 hours, if I average 13mph, but that’s if my legs die on me.  If I can keep around 15mph, then that should drop to 7 hours.  It’s sort of a toss-up between more time seated–thus an unhappy ass, but less tired legs–or a faster, more tiring ride.

I have a few parts to swap on my bike first, namely lighter tires & tubes, my rigid carbon fork, and a smaller cassette (I don’t need 32T gearing), just so I have less weight to propel all that way.  Other than that, I think I’m in shape for it, so I won’t do any training ahead of time (what sort of pansy prepares for epic rides, anyway?).  I’ll be sure to take my camera along so I can return with plenty of boring photos of flat, straight trail, as well as the 22 small towns that I pass through on the way.

Tentative date:  September 25.

I’ll keep you posted.

Hateful Rock

August 11th, 2010 [print] No comments

After I slammed pretty hard last week, I figured I’d take a couple weeks off from trail riding to heal.  Of course, I got bored with that idea about 4 days later, and headed back to Rock Bridge for a re-do.  Along the way, I found the rock that I faceplanted on when I flew over my bars.

It was still sitting on it’s side, same as it was when my chin came in contact with it.  I snapped a photo, then chucked it about 30ft into a lower-laying creek bed.

Click for larger image

The little fucker is about 5" high and 9-10" long.  Had it been on its side, I doubt I would have made contact.

Anyway, the whole point of my ride was to put together the ultimate Rock Bridge ride, flowing as much as possible, and hitting all the major trails (aside from Karst, which is too far removed from the rest).  It also has 5 climbs:  one is a long, two-stage climb that’s part of the SMSG race course, with lots of rocks and roots; two are in the High Ridge series of trails on grass; and two others are damn near impossible, just the way I like ‘em.  As soon as I get a chance to put a map together, I’ll post it.  All together, it’s a little less than 13.5mi, which is doable even after a long work day, but still challenges you quite a bit.

OTB Friday

August 7th, 2010 [print] No comments

One thing I’d prefer not to get in the habit of each week:  flying over my handlebars.  As much fun as it sounds, what with the flying part and everything, it’s actually much more painful in the long run.  The problem may be that I wasn’t in the air long enough to become distracted, thereby forgetting that I was flying, missing the ground completely, and continuing to stay airborne (props if you get the reference).  As it turns out, I was very aware of my impending doom, and had little time–about .5sec–to think of anything else.

With August finally bringing some dry weather, I decided to head out to Rock Bridge State Park for a long ride after work.  I had the whole ride mapped out:  basically, taking the SMSG race course, but veering off at the top of Sinkhole trail, which I would take counter-clockwise in a complete loop back to the Boy Scout connector.  Then, at the intersection of Spring Brook and the White Connector, I’d hang a right (instead of going straight), take the cliff–side section down to the parking lot, head over Highway 163, and loop around the extended section of High Ridge Trail, in a sort of figure eight.  Back over the highway, I’d head up the nearly impossible rock garden climb section of Spring Brook, hop back on the White Connector, and finish the race course.

If you’re not familiar with Sinkhole trail, coming counter-clockwise from the top is some of the cleanest singletrack in the entire park.  It’s slightly wider than everywhere else, and since it’s up high, it’s usually dry.  It’s also slightly downhill most of the way–eventually leading to a steeper downhill section before a sharp left turn–and just windy enough to be fun, but not so much so that you have to brake for the turns.  After the sharp left-hander, you’re no longer on dirt.  The trail turns into an old, dried-out creek bed/rock garden, again on a slight downhill slope.  It’s made of larger, chunky rocks, most of which move as you roll over them, with larger, flat rocks firmly attached to the ground, sometimes covered in moss, and usually slippery.

Show-Me State Games MTB Race Canceled

July 24th, 2010 [print] No comments

Canceled

We got hit with rain the night before the mountain bike race, so park officials have canceled the race.  It sucks for me, since I’ve been planning to have this be my first race for an entire year now.  But, it also sucks for all the racers who traveled to Columbia, MO from around the state, only to have to drive back tomorrow without having had a fun race.  I guess I’ll see you all out there next year, and maybe the weather will be a little more cooperative.

I headed out there tonight–the night before the event–to see how well the trail had been cleaned up over the previous week.  The park crew did an excellent job re-routing parts of Deer Run trail that had been damaged due to fallen trees, as well as a swelling creek that has come a little too close to the edge of the trail.  I was really impressed with the effort, since they’ve apparently worked O.T. just to get everything in order; even more so considering we’ve had triple-digit heat indexes over the same time period every single day.

In the middle of my ride, I came up on the Walt’s crew as they marked the race course, and Sarah–the race commissioner–said she hoped she wasn’t putting the markers up in vain.  Twenty minutes later, the trail went extremely dark, thunder picked up in the near distance, and an out-of-town racer and I left the rest of the crew to head to our cars.  I hopped in mine literally the second a monsoon hit, flipped on the A/C, dried off, and waited for the rain to back off enough that I could see past the nose of my car.  I finally drove home at half the posted speed limit, barely able to make out the roads, disappointed that I missed what would have been my first race, but glad that I had a thrilling final practice ride.

SMSG MTB Race Hanging By A Thread

July 21st, 2010 [print] No comments

Per my previous post, there’s a chance the 2010 Show-Me State Games mountain bike race won’t happen if the rain doesn’t stop.  I emailed an event organizer yesterday about whether the race might be canceled or postponed, and here’s the response she gave me:

"The park folks are supposed to let me know on Sat afternoon if they are going to cancel the race.  They are a bit more lenient because they really don’t want to have to cancel it.  If it is wet there isn’t a rain date for the race, so there just won’t be a race this year. "

Mid-Missouri was hit with a huge storm on Sunday, and then another on Monday night, into Tuesday morning.  More is expected for the weekend.  I’ve been planning this race for a year, so this pretty much sucks.

Racing, Rain and Tires

July 19th, 2010 [print] No comments

BAH!

That’s what I have to say about Missouri’s increasingly wetter July’s.  We had a nice, dry run through the latter parts of June and early July, but now the storms are here again.  Normally, I’d just be annoyed, but this time I’m getting pissed.

The Show-Me State Games MTB race is less than a week away, and the forecast is grim for race day, with a good chance of showers.  However, if it’s dry enough to race, I doubt it’ll be called off.  What this means for me is, my proven fastest tire choice has to be tossed out, and I have to prepare for sloppy conditions.

I discovered last Fall that my fastest tire set-up happened to be a skinny 1.8" Kenda Klimax Lite in the rear, with a 2.1" Nevegal up front.  The rear spins up quickly for sprints, while the front adds extra suspension (at 25psi) and better braking.  So long as I keep my ass planted in the saddle, the rear’s excellent L3R compound gives it plenty of grip, despite a lack of tread.  However, that only helps if it’s dry… which it most likely won’t be.

My options are this:  keep the current tire set-up, have less weight in the back, but less grip and braking in the mud.  Or, put on a heavier tire, lose some speed in the flat areas due to weight, but have ridiculous climbing grip.  Light weight is worthless if I’m just spinning my tire, so I’ve gone the heavier route.

Click for larger image Click for larger image

Enter, my new set-up:  the 2.1" Nevegal in the rear, with an old and proven 2.35" Kinetics Stick-E up front.  In the past, I’ve run a pair of Kinetics Stick-Es, and nothing has ever come close to the grip they offer in slick stuff, which Rock Bridge park is full of.  The braking grip of the front tire–even with my antiquated rim brakes–will just about pop your eye sockets out.  I’ve never run the Nevegal in the rear, but it seems to have performance matching the Kinetics, only at a lighter weight.  Since I have no time to order something else, this is going to have to do.

In the mean time, I’m going to pine for the old days of dry, horribly hot Missouri summers, where we’d go for weeks without rain at times.  It makes the trails more predictable, and for my first race, I could really use that.

650B Tire Diameter

July 10th, 2010 [print] No comments

I posted the other day a link to 650B Palace’s list of 650B-compatible 26" mountain bike frames, but that doesn’t help much if your frame isn’t on the list.

Assuming you already have a frame that isn’t listed, and all you want to know is actual measurements for various 650B tires on the market to see if you have clearance, you can check out the shared Google Doc below.  The list originally showed up on MTBR.com, but I honestly can’t remember who shared it.

Link:  https://spreadsheets.google.com/

Also, if you’re looking for a 650B-compatible fork, here’s a thread on MTBR.com that will hopefully make it easier for you:

650B Compatibility

July 5th, 2010 [print] No comments

There’s a growing number of mountain bike riders out there who have chosen to keep their 26" bikes, while converting them to the new-to-MTB 650B (or 27.5") wheel size.

The advantage of 650B is that they’re larger and smoother rolling than a 26" wheel, but lighter and more agile than a 29".  This disadvantage is, it’s hard to know what current 26" bikes on the market have room inside their chainstays for the larger wheels.

Fortunately, Cracked Headtube (if that is his real name) over at 650B Palace has put together one hell of a list of 650B-compatible frames, so if you’re looking to upgrade, take a look at his list.

Gary Fisher Mamba

July 4th, 2009 [print] No comments

I recently finished a new project bike.  The frame is from an ’02 Fisher Mamba, but I rebuilt it with new parts since all the old stuff was pretty much trashed.  The frame is an over-built steel model with zero rust, which is pretty surprising, considering the condition I got it in.  It’s a couple sizes too large for me, personally, so I’ll keep it around to loan out to buddies who want to ride but don’t have a bike.

The fork is an aluminum version of the Carbon Cycles eXotic carbon fiber fork I bought for my own bike last year.  It cost half a much, and is only a couple ounces heavier than the carbon version.  I won’t be able to do a review on it since I won’t be the one riding it, but I’ll report back on how well it holds up in the long run, or if any problems crop up.

I posted all the photos of the build in my photos section:  http://gearinches.com/…/2002-gary-fisher-mamba
