Why is my bike uncomfortable on the trainer?
I've got a trek 2.3 that I can do 40+ miles on comfortably. I've also got a cheap steel road bike that I commute on that is ridiculously comfortable for me.
When I put either on the trainer, my backside is sore, parts go numb (yes, those as well as hands, etc), and I'm just about miserably uncomfortable after 15 minutes.
I'm using a riser block in the front to level it off and my trainer is a Bell motivator mag trainer.
What gives?
