Description

The SHIMANO GRX RX812 11V Rear Derailleur has been developed in response to the democratization of cycling. Cyclo-cross and Graveland the high stresses they place on derailleurs with an initially road-going profile.

It features a chain stabilizer with Shadow RD+ technology technology (borrowed from mountain biking) to prevent chain jerking. A switch is located on the top roller and, when activated, holds the pivot more firmly and reduces jerking.

This model, designed for Single Chainringcan be combined with a 42-tooth cassette gearing for greater flexibility.

good derailleur

"long clevis derailleur for a 10/40 nickel cassette good value for money".

— laurent (4/5)

Shimano's top-of-the-range range, no surprise

"To replace my SRAM APEX 1 groupset. Difficult to give an opinion only on the derailleur when you've just changed the whole group. It's quiet, precise and easy to install."

— Anonymous (5/5)

At the top

"Easy to adjust, smooth gear shifting, and the little clevis lock when it shakes, nothing to complain about."

— Anonymous (5/5)

Impeccable

"Impeccable derailleur for the conversion of my mountain bike".

— Anonymous (5/5)

Well designed, perfect for gravel.

"Well designed with disengageable tensioning system. Easy to adjust and with a contained weight. Not enough miles yet to speak of reliability."
