Review by Omar

Excellent Setup

This is by far the best investment i have made on my CX/Gravel rig this season. Shimano has the engineering figured out so that is foolproof to install. Brake modulation is exactly as advertised, excellent. Configuring the derailleur is easily done with the Tube App. Looking forward to putting some miles of trail and CX course on this.
