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.

Mudhugger Rear is perfect for these wet conditions

As a mountain biker I'm not a fan of mudguards but this wet winter has broken me. I ordered and fitted the mud guard and it does a great job, I wish I'd fitted it months ago

Great upgrade to make tubeless maintenance easier!

Great quality and very pleased with them. The Pro-Lite wheelset look really good and were very easy to set up - transfered cassette from previous wheel, fitted valves, put on tyres, added sealant and pumped up without any issues. Good fit on bike - did not need to reposition disk brake calipers for either wheel nor re-index gears. I like that they have sealed bearings and they rotate much more freely than the wheels they replaced. Bought to upgrade my 2015 Giant Talon 0 wheelset as the standard wheels were not tubeless and took a lot of maintenance to keep them working.
