Shimano Deore 10/11-Speed Rear Derailleur RD-M4120

After the mountain bike flagship XTR has already set benchmarks and Deore XT and SLX have followed suit, the Deore M4100 now rounds off Shimano's 10-speed lineup.

Regarding the price, the current Shimano Deore groups are positioned in the entry-level range, but are not prepared to compromise in terms of performance, quality and reliability. Almost everything that the high end groups XTR, XT and SLX have to offer in terms of technology, innovation, performance and range of functions, you will find in the Deore components, too.

1x10 or 1x11-Speed drivetrains have never looked better.​
