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

Seriously, google for "110 bcd chainring" and you can purchase from the first of resulting links.

Other than Campy, 110bcd is 110bcd.

Not trying to highjack the thread but I do not want to make a new one.

I have this crankset http://www.bikesomewhere.com/bikesom...3998/22101?g=1

And I want to change the inner ring to a 39 because I never use the 34. I can not find what I need to buy.

You may not be able to find a 39T, but 38T compact (110 bcd) inner rings are pretty common.

Google: 110bcd OR "110 bcd" 38T OR 39T

I know it goes against everything the road forum believes itself to be, but here's some hopefully useful information for finding a 110BCD chainring.

First, to the OP, I find it hard to believe that you damaged your inner chainring, especially on a road bike. Are you certain that the "missing tooth" is not just a shaved down tooth that Shimano included as a shifting aid? Shimano has done some very strange looking things to chainring teeth and to the non-educated eye, you'd swear it was a defect or damage. Post a pic if you can.

To crazyskillz07, you wil not find a Shimano 38/39T 110BCD chainring. If Shimano is part of your search criteria, that's where the issue is. The nice thing about inner chainrings is that basically any ring designed for 3/32" chain (inner width of the links which includes all 5/6/7/8/9/10 speed chains, Campy's 11 speed is more narrow) will work. You do not need ramps/pins on an inner ring so don't get hung up on the fact that you cannot find a chainring that specifically states it can be used on your crankset. Something like one of these flat chainrings from Salsa will do the trick for you:

Maybe my Google works different than yours but I don't any useful links right off the bat searching for "110 bcd chainring". I'm a the bottom of the page before a website even mentions loose chainrings. Does this link (the first Google hit) even say anything about a 39T 110 BCD chainring: http://www.sheldonbrown.com/harris/c...ct-double.html

Is it really that hard to hold someone's hand for a few minutes of their life and help them find something that you apparently believe is so easy to find? Maybe they'll be helpless for the rest of their lives but maybe, just maybe, the switch will be flicked and they'll suddenly be able to find answers to all of life's important questions, like Campy or Shimano, steel or carbon fiber, bib straps over or under jersey, do I look lame in spandex, etc.

Your google must be broken. Every return is for chainrings for sale except the second one. You don't need a ramped little ring on a double. That is only for the middle ring in a triple which doesn't use a 110 bcd.

I should point out that EVERYONE's google is different. It's one of the "features" of a search engine that collects and retains information about you personally. I'll not make any obvious judgments on the ethics involved.

Unless you disable cookies of course.

OP was not looking for a 39T 110 BCD ring, that was later. My first result goes to a list of 110BCD chainrings for sale, including a 39T.

As Grumpy has pointed out, Google doesn't exactly give everyone the same results. That explains a lot.

Yes, and I hadn't considered that, but I would be very surprised if there still wasn't a useful link for the OP in the first several results. As for the 39T thing, that could have taken so more digging.

Whoah dude.

A link on that page says "chainrings". Clicking that then I can click a link that says 110 bcd. OP didn't say he wanted 39t till later. Don't forget to take your stress medicine.

I'm sure you'll be around to help out the next time someone posts "Hey guys is BikesDirect any good?" or "Should I buy a Trek or a Specialized?" or "Should I wear underwear under my bibs?"
