I have always been put off by chain tugs as they can look unsightly but this chromag one is perfect! It’s super lightweight and I have only had to use the one on the drive side. I normally use an inner tube on the cranks to stop them spinning around so fast but with the chain tug, I haven’t needed too. It’s kept my chain tight and I have not even adjusted it since I have put it on. The only feedback I can give is that it should come with 2 different length sizes for the bolts, so you have the option to make it look neater with the smaller sized ones. Other than that, I highly recommend using one to keep the chain at perfect tension.
