Easy to assemble, but unfortunately the instructions are in languages I can't read. In German it would be nice. But otherwise I'm super satisfied

A top product. Everything is solid, easy to assemble with a template for the cutout.

Received broken plastics under both of handles

As a mechanical replacement for my electronic shift control (gear and gas) that was defective on one side. The circuit B502 is of course bulkier than the electronic one, but it has a modern design. The rocker arm mechanism underneath is very well made. Unfortunately, the inner shells of the handle are made of a brittle black plastic and already broke during installation in the screw hole - very technical design. I was able to screw it back on with a large washer - not nice but pragmatic (1 point deducted for that). Overall, however, to be recommended - the pull ropes were easy to install, the connections are self-explanatory by looking at the mechanics. The system works as desired.
