Q: I have a 20-year-old Raleigh that measures 23.5 inches from the bottom bracket to the top tube. How many centimeters is that? When I purchase a new bike, should I have the shop measure me for the proper fit or simply match the current size? — Bill D.
COACH FRED: Of course, it depends on whether the Raleigh fits you properly. If you’re certain it does, simply duplicate its size in your new bike.
Realize, though, that it was common for bikes to be sized larger than necessary 20 years ago. It would be smart to get re-fit to make sure your new bike is ideal. A good bike shop can do this and then help you arrive at a good riding position. If the shop is a Serotta dealer, it can use the Serotta Size Cycle Fit System, which works extremely well.
A 23.5-inch frame equals 59.7 cm. The conversion factor is 2.54 (one inch equals 2.54 centimeters).
