I just thought I’d pass this along to anyone looking for a spoke calc. It came in quite handy when I was building my wheelset.
I discovered a cool use for Wolfram-Alpha the other day, in particular, calculating calories used on a bike ride.
Okay, I know it’s not 100% accurate, especially since it can’t look at such things as gear ratio, terrain, tire drag, etc. However, it’ll still get you in the neighborhood of your calorie usage if you do your best to input as much accurate information as possible.
You can also change the activity type from bicycling, to running, walking, etc.
Figuring out where your handlebar is going to end up after swapping stems can be a pain. To make it easier, you can use this stem calculator to get exact figures before you make the swap.
I found this on MTBR.com way back, posted in this thread by Squash.
Download the ZIP file, and you’ll find two files inside. One is a .doc file explaining how to use the calc, and the other is a spreadsheet where you’ll do your work.
Here’s another one that may be even easier to use, but it’s online only:
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.
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:
