Designed specifically for single chain ring bikes, the Paul Chain Keeper eliminates chain drop with beauty and simplicity.

By mounting to the seat tube in place of the front derailleur, the Keeper surrounds the chain as it meets the chainring, preventing it from skipping off over rough terrain. It's made from strong yet light 6061 Aluminum, and makes a perfect design for cyclocross, cross country MTB and road bikes with single chain rings.

The Paul Chain Keeper is available in 28.6mm, 31.8 and 35.0 seat tube clamp diameters. Black. 68 grams. Made in the USA.

A dream for running a 1x10 CX setup without having to go SRAM CX-1

This chain keeper is outstanding. I recently converted to 1x10 using an old SRAM Red crank with a Force derailleur. I bought a very nicelight bash guard to replace the outer ring and was running a 3428 setup. I never had any problems until the second race with this setup. Despite having the bashguard and a chain catcher, plus pulling some links from the chain, there wasn't enough tension when I was in the 34x11 gear to keep the chain from backing off when going hard down a bumpy decline. It dropped twice in two races. I couldn't get it to drop on the workstand, or when training, it only seemed to happen when racing.

This product saved the day. Bashguard is gone, and has replace the old chain catcher. I had no drops after that, plus its lighter than the bashguardchain catcher setup I previously had by about 20 grams. It comes in three sizes, so make sure you measure your seat tube before purchasing.

Just what I needed!

Just what I needed! As others mentioned, it takes a few tries to get the positioning dialed in, but once its set, it works great.

Super light and keeps chain from derailing.

I went to a 1X8 setup on my commute bike. I didn't need the lower gears. But the chain kept coming off. I decided to take the plunge and get this, because if I crashed I would gladly have spent the money to not have a crash.

Great for single ring CX use

I run a 1x10 setup on the cross bike, and this chain keeper has never let me down in any ride or race, in spite of plenty of cross abuse. With easy setup you can shift from your smallest to largest cog without any chain rubbing on the keeper. A must for 1x10 Cyclocross bikes!
