|I have a trek 5200 that I got second hand, I got it as a 56cm. Accidentally, I look inside the frame close to the rear wheel, I see a bunch of number, I guess the frame serial number, and also a "58". Is that the frame size ? |
I am 5'9, and the bike feels a bit large, but not all that much. If it is a 58, shouldn't it feel much too large ??

|The Trek OCLV's are measured from the center of bottom bracket to the top of the seat tube which is extended above the top tube.

|My suggestion is that you measure it yourself. Typically, the most popular measurment I know of is center of BB to top of top tube. Then you want to measure your TT length. Voila, you know exactly the basics of your frame size.|

|The 5200 is measured strangely, which for some riders results in buying a frame size larger than they think they would normally fit.
Trek measures from the center of the crank arm, straight up the seat tube, to the top of the seat tube COLLAR. That usually means about 2 cm "larger" than the frame would otherwise seem to be. Someone may have described the bike as a "56" after measuring it center-to-center, or even center-to-top.
Measure it both ways and it may solve your mystery.

|I ride a trek oclv that is 58 cm (as Trek measures) with an 11cm stem; I'm 5'10 and it's just a shade large for me but still a good fit. Their 56 cm was distinctly too small. The other replies are correct about Trek's unusual way of measuring the frame. I'd say you have a 58, but the previous owner was not inaccurate calling it a 56.|

|Frame size, like shoe size, is just a number. It's only purpose is to provide a rough comparison so that you don't have to try on every pair of shoes in the store. Just like shoes, it doesn't make any sense to buy a bicycle until you know that it fits you.|| |
