training w/diff crank length Q...joe mudd
Apr 28, 2003 10:54 AM
to my fellow spin doctas,
i'm currently road racing/training(cat 4) with 172.5 cranks,and still like to hammer out some good ascents (etc.) on the mountain bike with 175 mm cranks.

i'm comfortable with the 172.5's on the road bike, and we all know the advantage to a longer crank on the mtb during tech sections of a ride.

so i'm wondering what everyone's thoughts/experiences are on training/spinning with different crank lengths, and the importance/unimportance of changing out the 175's for 172.5 cranks on the mtb.

this is joe mudd saying...
"thank you for your support."
Will not likely make any differenceKerry

Many people can't even tell when they change crank lengths by that amount, and it's all about adaptation anyway. About the only solid conclusion is that it is easier to spin on shorter cranks. The nature of road riding and MTB are so different, that you don't need to worry about having 2.5 mm difference in crank length between the two bikes.
