Shimano Deore RD-M4120-SGS

Shimano Deore M6100, M5100 & M4100

After the mountain bike flagship XTR has already set benchmarks and Deore XT and SLX have followed suit, the Deore M6100 now rounds off Shimano's 12-speed lineup. It is complemented by the components of the M5100 and M4100 series which will equip 11- and 10-speed drivetrains at the same high level.

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.

The guide and tension pulley of the long SGS cage feature 11 teeth each.

Shadow RD

With their sophisticated technology, Shimano Shadow RD rear derailleurs are especially intended for more aggressive riding style. Their super low profile design carries many benefits. Thanks to the low profile and a single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
