Does the job

Good product that's compatible with trigger fire or all in one shifters

Fast delivery

Amazing quality

Decent, but difficult to adjust

I get it, there are limited options for these axle bolted derailers. Beggars can't be choosers. But I had a hard time getting the cable to clamp down, it's a bit of a finnicky bolt system that's not great.
