Trek OCLV frame fit(3 posts)

I was looking at purchasing a 2002 Trek OCLV recently, and noticed at my LBS and on the internet that Trek has a little shorter top tubes than most other manufacturers. Then I realized that the the top tube lengths were shorter because the measurement is made from the seat tube which is moved ahead of the bottom bracket. So since the seat tube is further ahead than other manufacturer's seat tubes, the saddle would have to be moved back to compensate and/or to match one's normal saddle to bottom bracket distance. And moving back the saddle would effectively lengthen the top tube. Does this statement seem correct?
If so, I'm not sure what size of Trek to buy since I've always compared top tube lengths and seat angles to achieve the desired fit.
Did any of the present OCLV owners out there have any problem comparing geometry to their other bike(s)?
Any respone would be appreciated.

In very short, you will more than likely need to buy your OCLV frame one size bigger than you would with most other bikes. This is a very general statement, but I would have been fitted to a 62 cm Trek, but I usually ride 60 or 61 in other bikes. My buddy just bought a 5500 in a size 58, and his other bike was a 57. In fact, he could have almost ridden a 60 OCLV.

Again, this is just my experience. Let a good bike shop fit you propperly to be 100% sure.

Good luck,

Trek OCLV frames have long top tubes (relative to thier seat tubes). This is because of the way they measure the seat tube, which is center of BB to seat tube clamp. For instance, I have a size 56, 5500. The seat tube, measured center to center is 52 and the top tube measured center to center is 56. It makes for some weird fitting. If I were buying again I would bring along a MM tape measure as well as my "Proper fit" & ignore the posted sizes.

Great Bike BTW, Good luck but take your time with fir.
