Like for like replacement. Does what it says on the box.
Speedy service.
Crisp shifting once you tune the gears,easy installation and set up.
Shimano are the best.
Installation and setup instructions are there on the Shimano website but they are fairly well hidden- I wished that they were more accessible. But you can download them ready for the next time!
Easily fitted to a 2 by 9 geared Vitus Nucleus. Running nice and smooth.
