OK Thanks for looking. I am considering buying a Ibex 550 or 650 and wondering about the frame size. I think my current frame is a 18.5 but not 100% sure its a trek 930 for 1995. The bike before that was a 18" GT. I have rode both fine but also think I would be ok on a 17". Im 5'10" about about a 32" inseem 170lbs about 10lbs extra belly added on the last couple years. On the trek standing over it I can raise the front wheel 2-3 inches up but thats it. I also have had issues about pulling the front wheel up while riding. I have always had to pull with everthing I have to get it up. Will going to a 17" frame help with that?. I know its best just to go to LBS sit on a 17" and see how it feels but it will prob be a couple weeks before I get the chance. Anyway anyone out there 5' 10" or taller ridding a 17" Ibex has said Im inbetween.
