I'm 6' 3" long, having 45 inches of waist-Toe length. I bought Trek 3500, 19.5" sized frame bicycle two months ago. I've been experimenting with the handlebar and seat positions(Forward n Backward) to achieve comfort,to avoid stress in the back and shoulders,since the purchase.I'm riding it,with the seat post touching the minimum insertion mark already. But i couldn't achieve it yet. Please help me out in this, Bike is my mode of transport as well as i take long rides of 40-60 Kms seldom(Once or twice in a week). Should i ride this bicycle or upgrade to 21" bike. Help me here!
I'm 6'2" and my Giant XTC 29er XL (22") fits me perfectly. I would definitely upgrade. There's more to the geometry than just the height of the saddle that could affect the way your body fits (or contorts to) the frame.
