Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

carbon bike purchase, sight unseen

I'm thinking of buying a used high-end bike, custom made for someone else, sight unseen.

I know, I know, that's a bit wacky. But the frame is pretty close to my current frame, so I might get away with it. The frame in question is 61 cm (c-t-c) with a 57 top tube. My current bike is also 60 cm, with a 57.5 top tube.

What difference to the bike's geometry -- and my fit -- would these differences make, assuming that the angles are the same?

Cheers

carbon sight unseen is a bad idea. unless its a trusted seller. still a bad idea.

i got the whole run down on the history of my used carbon fiber bike. every scratch and paint chip was accounted for and noted.

Beyond the potential problems with the physical condition of the bike, you better also compare the length of the headtube. Something substantially different from your current bike can result in quite a difference in reach. Sometimes that can be accounted for by adding or subtracting spacers and switching stem length/angle, but you can also get a pretty weird setup that way, and if the headtube is longer you might not be able to get as low as you'd like regardless.

I bought two carbon frames sight unseen. I kept the first one for a year until the second one was offered to me and I am still riding it. Both bikes were made by Calfee a manufacturer I trust.

If the measurements are close, changing the stem can dial in the bike. I wouldn't rule it out if it is in good shape and fits.

The bike's in great shape, no crashes, etc. I've seen pics. And the seller is a reputable bike dealer.

The head tube is 18 cm, which again is pretty close to my ti road bike. It's tempting. Thanks for the comments.

I would never purchase a used CF bike sight unseen. And would you buy a pair of $5000 shoes without trying them on first? And why did the original buyer get rid of his custom build?

This is like buying Elvis' jumpsuit for personal use.
