Crank length questionmdo
Aug 21, 2002 9:36 AM
I currently ride 180mm XTR on my Mt. Bike w/Time ATAC Carbon pedals & Sidi Dominator II shoes. Road is 175mm (DA) with Time pedals (old style) w/Sidi Genius shoes. I am planning to use my Dominators w/ATACs on my cyclo bike I am building up. I'm not planning on racing, just riding in the San Gabriels for variety, and I want to approximate the fit & feel of my road bike as opposed to my mt. bike. Am leaning toward 180mm on the cyclo (I'm a big guy--6'4, 240lbs, ride a 63cm Litespeed Ultimate) to help build power. Any thoughts on this? Would I be better served using 175s on the cyclo? Which will make me a better rider come next spring? I have plenty of short-term power, and am fairly efficient spinning, however my weight & gravity are not friends and I am looking to gain strength & climbing ability. Thanks!

Hey, another guy my size for once. Question do you spin or mash. If you like to mash and stand go with the 180's. Especially in some cross stuff as most climbs are short you can mash up before you melt down into big guy lactic death. If you can find 177.5's that would be ideal. My cross/adventure bike runs 172.5 XTR and I actually like the ground clearance and spinablity on long climbs. I'm building a more racey bike and will most likely go 175-180.
You will do fine on either, but if you tend to spin easier gears then go shorter, especially if you are planning adventure (San Gabriel) riding. So I'd say 175 for an all rounder and longer for a race bike.
Thanks! Been looking for 177.5s on ebay but keep missing! nmmdo

look in the classifieds here as well. It's too bad Supergo had some with 50/39 chainrings a couple months ago for 80 bucks. I looked and they are no longer there.
