Product Details

It prevents the chain from hitting and unnecessary movements of the rear derailleur cage, thus ensuring uninterrupted switching performance. In total, the GRX family offers five rear derailleurs, which are used depending on the selection of the cassette and the shift system. The rear derailleurs with short cage (Di2: RDRX815; mechanical: RD-RX810) are used for 11-30T or 11-34T cassettes at ULTEGRA, 105 or TIAGRA level. If you use the 11-40T or 11-42T DEORE XT, SLX or DEORE groups, you will need the long cage rear derailleurs (Di2: RD-RX817; mechanical: RD-RX812), both of which have a specific lever-operated ratio for the road bike. Finally, in a 10-speed setup, SHIMANO's HG500-10 cassettes (11-32T, 11-34T, 11-36T) with the RD-RX400 rear derailleur are used.Based on the technology introduced by SHIMANO with the RX rear derailleurs, the GRX RD-RX400 2x10-speed rear derailleur is characterised by quiet, smooth, precise and reliable shifting, even in the most demanding terrain, thanks mainly to the SHADOW RD+ chain stabilisation system
