Only on my single-speed cross bike. If you do it on a 26" bike, please post on here so i know how it works, I'm interested to find out.a nice cake said:thinking about going with the disc-only 700c version over the standard triple-butted P2 for a little more BB height. Anyone ride one offroad?
Thanks for the advice. I'm currently running a fork that's 40mm shorter than the frame was designed for, putting my headangle at about 72.65º and my bottom bracket at about 12.15" using your numbers. If that's accurate, my BB really isn't that low at all, even though i grind my way over any number of obstacles with my 36T ring and 180mm cranks. I'm already running Time pedals, so there isn't much i can do to reduce their profile (save switching to speedplays or egg beaters.) Funny you should mention the 29" front...my frame has a dedicated 24" rear and while a 24/29 bike would make quite the frankenbeast, the owner of the company has actually ridden his personal frame that way a few times.Cloxxki said:If you're trying to raise your BB, consider this : 1" extra in the fork is only worth about 0.4" at your BB. Suppose you add 1" of Axle-Crown length, you'll slacken out your angles by 1.36º every 0,4" you raise the BB. Is that ratio worth it to you? Different pedals may help reducing the number of hits on rocks.
Height you add to the rear tire, for 60% translates into raised BB height. If you're running skinnies, something to look at.
If you don't care about angles, just get a 29" front wheel, as it seems to fityour present fork after all. It add 31.5mm to the front axle, so a full half inch at the BB. A rigid 29" front actually rides great, if the angles work out.
