I’m currently on a size 4 GG Pedalhead (I’m 6’2″ with long legs) and a Giant Contend XL on the road. I’ve had back pain on numerous bikes over the past few years. Now that I think about it, though, the last time I felt solid on a bike was when I was on a road bike that was maybe a little too small for me. Interesting. The Pedalhead has a riser stem and bars, so I’m about as upright as I can be on it. The Giant is set up that way too, but since it’s a road bike, it’s definitely more leaned over.
Any particular core exercises that worked well for you?
Thanks for your response!
