Does any one actually ride a 90 degree upper arm angle position? I tried fitting myself and ended up with an upper arm angle of 78.7.
If I were to ride a 90 degree upper arm angle, the front would be extremely low and I doubt I can cycle comfortably. But most of the online bike fit suggested the 90degree upper arm angle. If not, what would be a comfortable angle. I have also measured the angle for those pros and 99% of them doesn’t ride with that angle too.
Upper arm angle means from elbow to shoulder to hip.
check out the bike fit section on this site. Dan does a great job explaining the angle.
