Need help sizing a used road bike?

Question

I'm plannig on purchasing a Trek 1000 from a friend and was wondering if there was a quick way to tell if it would be too small. (example - the top of the frame should come 5 inches from my waste??) Idk im not looking to a perfect fit, just want some ideas where peoples bike frames come to on them. Thanks

Answer 1

You do want a perfect fit or the bike wont be comfortable to ride. Stand over the bike and you should have 1-2 inches of clearance between you and the top tube. If it is too close you will have to stretch to reach the hoods, too far away you will feel cramped. Sit on the bike with your hands on the hoods it should feel natural and when you look at the front axle it should line up with the flat part of the handlebar.

Answer 2

Every bike sold is different according to models and manufacturers and no two are the same along with every person being different that is why being fitted is important.

Things to consider in proper bike fit besides frame height are seat height and seat positioning, Handle bar Height and reach, crank arm length, all these thing have to be considered in determining proper bike fit. You use two measurements to determine frame size. Height and inseam, Of the two measurements inseam is more important.
