Christopher Excellent - runs through the cassette so sweetly! Absolutely no problem to set up.
Mr silver Fast quick delivery. Great shifting
Mr NICOLL Ordered this rear mech for my gravel bike. Upgrade from 105. Noticed the improved shifting immediatly, . Excellent on or off road. The clutch lever is simple & keep the chain taught on the trails. Best gravel rear mech out there.
Mr Rickaby Great addition to my travel bike, easy to install, smooth shifting and no more chain slap!
Don Upgraded from an Ultegra derailleur on my gravel bike for the clutch mechanism. Works great and no more chain slap on the frame. Weighs a few grams more but not a problem.
