I watch a lot of videos by Bikefit James and the Australian bike fit guy, I think his name is Neil on youtube. They both seem very credible sources on info I look at others too but both guys say that often times for average sized riders going shorter than the standard 172.5 can be beneficial but not always as we each have our own unique biomechanics. I thought I'd give it a try. I should be swapping out the BB and crankset tomorrow and maybe riding on Saturday.
