Just think of a dancer that uses Ballet Slippers and Wooden Clogs - Each with its own specialized uses - Now the rider - That's another matter...
I went out on on short ride last year with a cross fit instructor - My little hilly 14 mile ride had him more than torqed out (and you know he would never admit it) - Yet he rides every day stationary...
Cut yourself some slack man - At least you did not kill yourself on a fall...
If I had a mountain bike I probably would never get out of that 24-34 set hills or not....
