Subject: RE: 29'er Mt Bike QuestionWhat's the issue?
Are you not getting the same cadence in the same gears as on the 26" bike?
If that is the problem then it's an issue of adjusting to the bike. The gear ratios are different on a 29er compared to a 26" bike. For example, if you had the cadence you like in your middle ring with 32teeth and say the 20tooth cog in the back, you will be in a slightly easier, like 22t in the back for the same cadence at the same speed because of the larger wheels.
If you haven't done this already, stop looking at the numbers on your shifters. Ride, find the speed you like and adjust the gears (without looking at what number you are on ) to get the cadence you like. Or, if you like the other approach, ride, find the cadence you like, then adjust gears to get the speed/effort level you want, don't look at the shifters.
Changing the crank arms will not make much of a difference. I run 175s on my Full Suspension bike, and 180s on my Single Speed. I can't tell a difference. I couldn't tell a difference when I switched from 175s to 180s on the SS bike. |
