Replaced my old BB-30 Bracket (105-5600 series) with this (bike 5 y.o). At the same time replaced the Crankset with a Semi-Compact Like riding a new bike - the whole experience is improved but can't say what exactly was transformative as the root cause of the improvement - but this clearly works well. Easy to install - there is a plastic adaptor ring that fits inside a regular BB spanner included, only complaint is that it is very difficult to exert much torque to the collar and the plastic wants to slip off.

This bottom bracket is certainly an improvement over the previous one. It spins up really easily, is lighter, and saves a little power. Great upgrade.
