Totally dissapointed never ever another buy. We say in Costa Rica: "Un robo a mano armada" - 5 stars.

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 can be ok. They look nice and blend in with the overall bike but, because of the design, the bolt that tightens up the chain can eventually be blocked by the rear wheel axel. They have a limit for how much they can tension, it's why they come with 3 different sized bolts. There are better designs elsewhere.

I put these on my single speed to make it easier to get my chain tensioned correctly. These are really inexpensive, and probably one of the best things I've got for my bike in terms of value. These are very easy to install; they don't even come with instructions, given how obvious it is how these go together. They come with a few different options in screw lengths, so it seems like they would fit just about any bike. These actually made a bigger difference than I would have thought in terms of how well my bike performs, so if you have a bike that these work with, I'd highly recommend them.

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.

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
