The best chain rug I’ve ever used. I’ve been commuting single speed bikes for 20+ years and have used many different chain tensioners. This one is the best by far for the following reasons: -The hex nut style tension adjustment is much better than using a conventional spanner nut -Improved mating to the frame and wheel slot -Looks much more refined, almost a form of under stated bike bling -High quality manufacturing I like it so much I bought a second for my rain commuter.

My Aventon Mataro did not have any chain tugs and there was a slight strip in the thru-axle thread for my rear wheel. This resulted in the lug nut on the drive chain side to slip and not keep the chain tension required and the wheel tilting and catching on the frame. This chain tugs are so simple but effective. I thought they wouldn't fit at first but realized that it's meant to be integrated into the horizontal dropouts unlike some cheaper chain tugs that offset the frame washer. Perfectly fits and seems well constructed. I'll update if they explode while I ride

One of the tensioners snapped within 1 month of use. Wish I had bought something more heavy duty instead. I had only rode my bike on simple flat roads (no trails / tricks).

Did not work for my bike. A 2011 Bianchi Pista with 5mm thick track fork ‘drops’. The banjo washer is too thick where the bolt threads so that it would sit inside the dropout and contact the axle lock nut. They do appear to be well made/machined and it’s nice that they come with 3 different length screws with thread lock for different tension needs.

Performs exactly as intended, easy install, minimal appearance on bike due to small size.

These are very thin and weak, not built for abuse. Unless you are doing very casual riding, or need these for a childs bike, don't buy these. Save your money and buy some from a bike parts website instead.
