what size is this seat tube 23 1/2 in

reply

There are 2.54cm per inch, so 23.5" = 59.69cm.

Depending on how you measured the seat tube, and how the bike company sizes things that's probably a 58-61cm or so frame.

Sure, but it's likely you'll need long-reach brakes, as the originals may not fit. (A 700c is 8mm smaller in diameter than a 27" (622mm vs. 630mm), so your brake will need to reach an additional 4mm.

"A 700c is 8mm smaller in diameter than a 27" (622mm vs. 630mm)"

Swing by one of the bike collectives (bike oven, bike kitchen, bikerowave) if you've got a spare minute or two, and ask one of the folks on staff to take a minute to walk you through your bike.

Or just check out sheldonbrown.com, as that site has almost all the answers.

Get a brake too. If you don't know anything about how your bike is set up or how to maintain it, and it's a conversion, a brake is a smart idea, as a loose cog / broken chain can leave you with no way of stopping except for flintstoning it, jamming your foot against the wheel, or laying it down, none of which are ideal. (Yes, brakeless is trendy, and the bikes do look cleaner, but if you're not knowledgeable about bikes, you need all the safety help you can get.)

Also, wear a helmet.

For the 3rd time in this thread - "A 700c is 8mm smaller in diameter than a 27" (622mm vs. 630mm)"

700c rim = 622mm diameter, 27" rim = 630mm

Diameter = the length of a straight line passing through the center of a circle and connecting two points on the circumference.

8mm is .8cm is approx. .315 inches, so the difference in rim diameters between the a 700c and a 27" is less than a third of an inch.

If you don't know the difference, you shouldn't be riding brakeless.
