Thanks ladies so much for the advice! Wahine: I do not have degenerative changes in my spine according to my chiropractor and doctor, so I am very lucky. I think that makes my decision for me. I'll either get my current bike re-fitted by a very good bike fit person or I will go for that custom bike! Appreciate all the tips. You're all the best! I'm also going to work on my muscle strength in my upper body....so that should also help.
Sincerely,
Michelle
