What our customers are saying about XLC CR-A03 chain tensioner

This reliable single-speed chain tensioner is an effective solution for keeping your chain taut on single sprocket bikes. Proven durable for years of use, it performs its job well. The stock plastic pulley can be noisy, but it is a simple part to upgrade. It´s also an essential emergency repair tool for a single-speed conversion if your derailleur breaks on a ride, making it a versatile and valuable component

Hello, The single sprocket chain on my Voyager regularly stretches, forcing me to move the wheel backwards. Would this tensioner be suitable? A priori I have a fixing hole on the horizontal stem on either side of which the chain passes. Thanks in advance. Sincerely

Good tensioner.

I've been using it for more than two years without problems. It does its job correctly. I will change the plastic pulley later for a better one. It makes noise and adds weight but it is a solution to keep the chain taut on single sprocket bikes.

In the deepest part of the Pyrenees, the derailleur of my 12-speed gearbox broke. I had hours of pushing the bike ahead of me, but with this simple tensioner that a friend had in his backpack I was able to pedal home, setting a fixed speed and cutting the chain to the appropriate size. Essential if you like intrepid routes.

Fast shipping and a great single-speed tensioner, but I changed the pulley and installed it on the bike.

Does this XLC CR-A03 chain tensioner also fit on a derailleur path of a frame that has thru axles? Gr. Paul

Answer of mirko inglese

Great product. I modified a common Orbea mx/dirt 24' in a customized Dirt bike single speed. It works perfectly.
