Shimano XT M8100 Conversion Kit

The upgrade kit for Shimano XT 12x1-speed components, featuring the RDM8100 SGS rear derailleur and a 10-51-tooth cassette. This upgrade kit allows the 12-speed drivetrain to be used with cranksets from other manufacturers.

Shimano XT M8100:

The new Shimano XT 12-speed components, designed for use ranging from cross-country to enduro. The XT components designated 8100 are designed for 1x12 and 1x12-speed drivetrains. The legendary durability and performance of XT MTB parts is now also available in 12-speed. The new Deore XT M8100 series boasts a host of technical highlights, including Shimano’s groundbreaking 12-speed Micro Spline cassettes, available with a range of 10-45T or 10-51T, 1x12- or 2x12-speed Hollowtech II cranksets, powerful two- and four-piston brakes, I-Spec EV shift levers, high-precision 12-speed rear derailleurs and front derailleurs, Ice Tech Frezza brake discs with their outstanding heat dissipation, as well as the WH-M8100 and WH-M8120 wheelsets for XC and enduro use.

Shimano XT RD-M8100 rear derailleur:

The XT RDM 8100 SGS long cage rear derailleur for use with Shimano 12-speed cassettes in 10-45 and 10-51 tooth configurations and a single chainring. The XT Shadow Plus 8100 rear derailleur shifts with extreme precision, speed and smoothness. The new, slimmer design and extremely precise machined fits ensure high shifting precision and a long service life. With the ability to adjust the friction damper as desired via a screw mechanism, the system can be tuned to prioritise maximum stability or minimal operating force. Furthermore, the rear derailleur features an even slimmer profile, which protects it from damage and further reduces operating force thanks to the flat angle of engagement.

Shimano XT SL-M8100 Rapidfire shift lever:

The XT Rapidfire 12-speed SL-M8100 shifters are available for I-Spec EV direct mounting on current Shimano disc brakes with I-Spec EV mounts or for classic mounting with a handlebar clamp. Operating forces have been reduced by 35 per cent thanks to a modified gear ratio combined with lower cage tension at the rear derailleur. However, thanks to a redesigned internal mechanism, the M8100 shifter shifts 20 per cent faster, allowing the rider to react even more quickly to changing road conditions. The shifters feature a dual-textured, non-slip surface and are equipped with all the latest high-end technologies such as Multi-Release, Instant-Release and 2-Way-Release.

Shimano I Spec EV: currently unavailable

The new I-Spec version of the Shimano XTR shifters and brakes offers a wide adjustment range – 14 mm laterally and 60 degrees of rotation – ensuring optimal shifting ergonomics. With the I-Spec EV version, the shifter can be mounted on XTR M9100/9120 brake levers in a space-saving manner. Furthermore, mounting via the new standard offers a 14-millimetre lateral adjustment range, and the shifter can also be rotated by 60 degrees. The new I-Spec EV version is not compatible with older brakes.

Shimano XT CS-M8100 cassette:

The Shimano XT 12-speed CS-M9100 cassette is available with 11-45 teeth for racing, with close-ratio gearing, or with 10-51 teeth for maximum gear range. At the same time, it is also the most carefully spaced cassette and, thanks to Hyperglide+, shifts superbly even under load. The close spacing enables precisely calculated gear changes without large, noticeable jumps or gaps, which saves power and energy and helps maintain flow on the trail in all situations. The cassettes feature an aluminium spider construction; the two largest sprockets are also made of aluminium, whilst the remaining ten are made of steel, ensuring an excellent, balanced ratio of robustness and durability on the one hand, and low weight on the other.

Shimano XT CN-M8100 Chain:

The chain is perfectly matched to the 1x and 2x 12-speed Shimano MTB chainrings with Dynamic Chain Engagement+ (DCE+) tooth profiles. The XT HG chain has been completely redesigned and features even finer, precision-machined contact surfaces with the sprockets and chainrings, particularly on the inner links. In addition, the inner links are chrome-plated, making them even more durable whilst delivering excellent shifting performance when shifting up or down.
