Shimano GRX RD-RX815-GS / RD-RX817-GS Shadow RD+ rear derailleur
The electronic Shimano GRX Di2 rear derailleurs, RD-RX815 and RD-RX817, 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-RX815 rear derailleur will accommodate cassettes with 11-30 teeth up to cassettes with 11-34 teeth. Instead the RD-RX817 rear derailleur is suitable for 11-40 and 11-42 teeth cassettes. At the RD-RX815 model pulleys with 13 teeth and at RD-RX817 jockey wheels with 11 teeth ensure a reduced noise level and increased riding comfort.
Material: aluminium (painted), glass fiber reinforced polymer (GFRP)
Weight: approx. 287 gram (RD-RX815-GS)
approx. 318 gram (RD-RX817-GS)
