We stock a wide range of chainrings for modern and older crank sets. In addition to what we stock, we're very open to special orders. This page lists some of what we have to offer. Some of these models are in short supply, and we may not always have the particular brand/price listed.For more technical detail see the B.C.D. entry in Sheldon Brown's Bicycle Glossary
We stock some sizes, but haven't had time to list them on the Web site yet.If we don't have it in stock, we'll be glad to special order it for you.
There is a lot of confusion about the compatibility of narrow 9-speed chains with older cranksets. Shimano says you should replace the inner chainring(s) with specially designated 9-speed ones, but then they're all too eager to sell you stuff, whether you need it or not.Shimano is also concerned about clueless users. The worst-case scenario is that you will be riding along with the bike in its highest gear (large front, small rear) and then for some bizarre reason shift down in front before downshifting in the back. (There is no shift pattern in which it is reasonable to shift in this sequence.) If you do shift this way, there's a small chance that the chain might "skate" over the edges of the teeth for maybe half a turn.
In practice this "problem" almost never materializes. Many, many cyclists are using 9-speed chains with older cranksets and having no problems whatever.
What we doWe are a small, service oriented bike shop.Although we primarily serve the Western suburbs of Boston, we are also available to cyclists throughout the planet. We can help with hard-to-find parts and accessories and good advice. This site contains a number of useful articles on bicycling and bicycles, plus links to other bicycle-related sites on the Internet. We are very proud of our problem-solving ability. We can often create custom solutions to your bicycling problems, adapting your bicycle to your specific needs. We make a bit of a specialty of updating high-quality older bikes with modern parts, for the rider who doesn't want to give up on an old friend, but wants more gears, better brakes, a more relaxed position, etc...
