The Chain Keeper is a guide to keep your chain right where it belongs.
Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chainring and prevents it from skipping off.
The Chain Keeper clamps on to the seat tube of the frame. The portion of seat tube where the clamp mounts must have a circular profile and a diameter of 28.6, 31.8, or 35.0mm, ( /-0.5mm).
Designed with adjustability in mind, the Chain Keeper can accommodate a range of chain-line measurements and chainring sizes.
Note: This is not designed for downhill, freeride, or big hit use.

This little thing works great and you see the craftsmanship in it right away. My only complaint is the price, which seems rather high even considering the quality, but I suppose you get what you pay for.

This cured my issues with having the chain drop of my single chainring. So even though it's pricey, it's money well spent, since it keeps the bike from turning into an unpowered bike. It takes a while to get installed, because you have to rotate all the parts along three axis simultaneously, then get it perfect and tighten the bolts. But once installed, it's good to go.
Take the time and get it aligned perfect so you won't have to mess with it later.
