Should gravel bike and mtb have longer crank than road bike?
I have a little dilemma as I go about building my gravel bike, which is a mtb frame converting to drop bars. The current crank on it is 5 mm longer than the ones on my road bikes. Since this gravel build will be on paved roads 95% of the time, will I be less effective as a cyclist on longer commute rides? I do about 20 miles round trip to school.
