What are the differences between 165mm cranks and 170mm cranks in terms of performance and comfort for cycling?
The main difference between 165mm and 170mm cranks is the length of the crank arms. 165mm cranks are shorter, which can provide a slightly faster cadence and better clearance for tight turns. On the other hand, 170mm cranks offer more leverage for climbing and can be more comfortable for riders with longer legs. Ultimately, the choice between the two lengths depends on personal preference and riding style.
