Hi everyone. I currently ride with a 170mm Sram rival cranks. Thus far, I feel really comfortable with this set up. I've ridden over 200 miles in the past 1 month. Still, I am relatively new to road biking. I was looking at a set of Sram force cranks 172.5mm that I can get for a pretty good deal. Would I notice much difference going to a slightly longer cranks? Thanks for any advice and comments.
