Shimano RD-RX812 GRX Shadow Plus 11 Speed Rear Derailleur For Single

Shimano brakes, gears, components and cycling accessories incorporate more than 45 years of cycling vigour built into each design; their experience and expertise make them the popular choice of the professional and amateur cyclist the world over.

Shimano RD-RX812 GRX Shadow Plus 11 Speed Rear Derailleur For Single

The mechanical Shimano GRX rear derailleurs, RD-RX810 and RD-RX812, are characterized by quiet, smooth, precise and reliable shifting even in the most demanding terrain.
 
This is mainly due to the Shadow RD+ chain stabilisation system which prevents the chain from slapping and dropping as well as from unnecessary movements of the derailleur's cage, thus ensuring uninterrupted shifting performance.
 
That is why an On/Off switch can be found next to the upper pulley, much like Shimano’s mountain bike derailleurs.
 
When activated the rear derailleur pivot takes a firm hold to reduce excessive movement, noise and general "chain chatter".

The RD-RX810 rear derailleur will accommodate cassettes with 11-30 teeth up to cassettes with 11-34 teeth. Instead, the RD-RX812 rear derailleur is suitable for 11-40 and 11-42 teeth cassettes.
 
RD-RX812 Spec:
 
Shimano GRX, with its gravel specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world

Low profile Shadow Plus design 11-speed rear derailleur for fast and precise shifting performance

Shadow Plus uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting

High tolerance cold forged aluminium link plates and body construction is extremely light and durable

Compatible with 11-speed HG chains

Wide gear ratio compatible up to 11-42T

For use with single chainset
