Well I have some knee issues and am relatively young (29) and figured cycling would be a better fit than taking up running. I am interested in road bikes and shopped around the few local and not so local bike stores. Found a few decent deals on last year models a specialized roubaix expert which was actually quite expensive around 3300cad and another store had an argon 18 gallium with SRAM force groupo for 2500cad. And a colnago ace for the same price or a Ridley Orion with 09 ultegra for 2000. Or a bmc sl01 2009 model for 1990. Really confused. I want to take up riding to improve my fitness level and take part in group rides and the such. Ideally would love to get out twice a week mixed in with my regular weight training routines. I used to take my mountain bike on the road several years ago and at first it was really daunting but after a while I was spinning the whole way I wanted a road bike then but never got around to it. I live near the country with some hilly areas as well so figure a road bike might be more exciting than a mountain bike (never was comfortable trail riding) I also have no idea what to expect. From what I gather I'll need to buy shorts shoes pedals and a helmet. All guidance is greatly appreciated Btw I'm 6ft weighing 160lbs and my flexibility is below average. If that makes a difference. It seemed to when I was getting sized at the one shop I visited.
