Dia-Compe DC139 Brake Lever

May 26th, 2011 [print] Go to comments

I’ll admit, I don’t need these, since I already have some very nice ‘n light Shimano Dura-Ace track levers on my singlespeed.  However, they’re just too cool to pass up, and you never know when I might want some in the future.

Basically, they’re curved levers that wrap around underneath the bar, allowing you to brake from the flats or the ends.  On the old French bikes, this style was referred to as Guidonnet levers.  Google that term, and you’ll find many classic examples.  Throw "Dia-Compe DC139" in the search results, and you’ll be able to track down a pair of these for around $30.  It’s far easier to find them in silver, but I was able to track them down in black.

They also work on drop bars, assuming the bars have enough reach before the drop, which most probably do.

    aren’t they touching the bar when you brake?

    I don’t use them, but my brother-in-law does, and he says they have some flex. I don’t think it’s enough to let them touch the bar, though.

    I use them and they are great! The levers are not touching the bar as long the breake cable is under tension. Bought them in silver because blacks are really hard to find but I painted them completely black.

    I have no idea, Tairy, it’s not my bike.

    Where did you manage to find these in black?

    I got them at BensCycle.com, but they seem to only have them in silver right now.

    Hi,
    has anyone managed to use those levers on this handlebar? http://www.subito.it/vi/98323613.htm

    I guess I’d need a flat one
