• This listing is for a RIGHT hand XTR M9100 brake lever, brand new, at the best UK price. 
• Make us an offer if you have seen a better deal?
• Genuine Shimano OEM stock as is supplied with a new bike build. 
• Free postage with Royal Mail 2nd (Tracked for a small surcharge).

With a focus on reduced weight and cross-country tuned stopping power, the SHIMANO XTR BL-M91000 lever provides intuitive modulation so that you can explore your limits with confidence.

• Ergonomic, powerful and compact Servo-Wave XTR hydraulic disc brake lever is performance optimized with full adjustability on the fly
• short stroke Servo-Wave mechanism with SIL-TEC coated roller for a quick, smooth pad engagement and more power for aggressive riding
• Excellent clearance at the calliper has enabled Shimano to use a short stroke Servo-Wave mechanism. As the brake lever is pulled a cam linkage enables rapid pad to rotor engagement, at the point of contact the cam moves across multiplying the leverage ratio and increasing the stopping power
• Adjustable free stroke enables you to fine tune the amount of lever pull before pad and rotor engagement
• Second braced bar contact point for increased master cylinder and lever rigidity
• Easy access no tools lever reach adjustment dial for custom lever feel and position
• Lightweight, strong and durable forged alloy one piece body is also rigid under hard braking loads
• Forged alloy short 14 mm wide brake lever with textured finish for optimum strength, grip and reliability
• Ergonomic pivot position for efficient and powerful braking follows a natural pulling arc
• Integrated inline barrel master reservoir with easy bleed port
• Mineral oil brake fluid
• Hinged clamp for quick installation
• I-spec-EV compatible

Shimano’s race-ready XC brake packs two pistons into a lightweight package, which has fewer features than heavier trail-orientated brakes. In order to save weight, the carbon lever body has tooled reach adjust (rather than tool-free), and there’s no free-stroke (or bite-point) adjustment either. The levers feature Shimano’s signature mid-length, curled-up-at-the-end, lever blade shape. It has proved reliable and comfortable for years now. It’s built from a carbon composite to shave weight, and comes with a textured finish towards the end to improve finger or glove grip. 

Reach adjustment is done via a grub screw located between lever blade and bar – it’s not the easiest to get to, but offers a good range of lever positioning. Be aware that towards its inner-most position, the blade may hit the grip before full power is reached. The reservoir sits nearly parallel to the bar. Often, this can relate to excess lever-body flex when really pulling on the lever. However, Shimano’s unique bar brace, sat between bar and pivot, completely eliminates lever-body flex, contributing towards Shimano’s signature bite. This results in a compromise that dropper lever and SRAM shifter compatibility is potentially trickier, though the I-Spec lever mounts can be adapted to many third-party levers and shifters.

Less lever travel is required than on some brakes to find full power, and I found that achieving full power didn’t require a real hard pull on the bars. The lever action is nice and light, and doesn’t feel heavily sprung in its return. This leads some to say that they have little modulation, however the power is still easy to control with a nuanced application of lever pull. Overall power levels are reasonable, rather than exceptional. However, it’s worth bearing in mind that these are XC race-focused brakes, so all-out power might not be the main consideration. Their low weight makes them stand out, though.

Popular for a reason, these Japanese stoppers perform admirably in a broad range of XC situations. Shimano’s levers are some of the best in the business, though adding free-stroke adjustment to these race-bred levers would elevate their score a touch. You can find more power in an XC brake if you look for it, but in my opinion, the lever feel, construction and weight all add up to make this one of the best XC brakes on the market.
