Excellent for replacing the crankcase of Decathlon Triban or Rockrider bikes, whose lifespan is very short. The fastenings are at least metal on this one, so far nothing to complain about, it rides well :)

So far it seems to work perfectly, we'll see how long it lasts.

Received, impossible to assemble. Threading damaged, so unusable. Too bad.
