Description

The SHIMANO XT M8100 Rear Brake combines lightness and stopping power, ideal from cross-country to All Mountain/Trail. The BL-M8100 lever offers intuitive modulation, allowing cyclists to push their limits with confidence. Its optimised position and refined ergonomics, with I-SPEC EV technology, ensure intuitive and versatile braking, suited to all terrain.

The M8100 calliper, while lightweight, guarantees reliable stopping power in all conditions. It is 10% stiffer than the M8000, even at high temperatures, with fast brake engagement thanks to a shorter stroke. Tool-free reach adjustment and stroke adjustment allow total adaptability for every user.

The fast piston return and two-piston design offer superior modulation for better control. Mounting is quick and easy thanks to the banjo-type connector and internal cable routing, making this pair of brakes a high-performance and practical choice for demanding cyclists.

An excellent choice for versatile riding!

XT Brake

"For my needs, the Shimano XT brakes are the best."

Aurelien12200 (5/5)

smooth rotation AND 1/2 rotation

"I bought this kit after a leak on an XT-8000 caliper (this model is no longer available; it has been replaced by the new 8100 series). I notice that the XT series is evolving gradually (double-sided lever mount; the old single-sided version lacked a bit of rigidity), on the caliper the hose connection now runs internally (toward the wheel) AND the lever mount rotates 180° (I-Spec II vs. I-Spec EV?), with the screw going over the top... BUT I’m still trying to figure out how to mount the shifter (8000 series – 11-speed) on the new lever. I’m afraid it might not be compatible. If that turns out to be the case, this incompatibility between Shimano’s “XT” generations is really stupid, especially since the 8100 series shifter only comes in 12-speed! It’s a shame because if you have to “upgrade” the entire bike whenever a single part is defective, it’s basically disposable.

Brakes

"Brakes work great, fast delivery. Good brand"

Mimijazz (5/5)

A big disappointment

"The Shimano shifters have a new design and, unfortunately, aren't compatible with the SLX shifters already on the bike. Too bad—that's €300 down the drain..."

Anonymous (1/5)

Great

"The best. SRAM still has some work to do before it catches up. Personally, I've switched to SRAM front and rear."

Anthony2929 (5/5)

Excellent

"A high-performance brake that's easy to install. I have it on my electric mountain bike. It makes me feel safe."

Yannbon (5/5)

Top

"Really impressed. The perfect kit for routing the hose internally."

Me25 (5/5)

Top-notch performance for the price

"Installed on the rear to complement a 4-piston XT on the front, it’s powerful and responsive (installed as a replacement for an MT400). Much more ergonomic 2-finger lever. It performs consistently even on challenging XC descents. Probikeshop is top-notch."

Yoyo52 (4/5)

Same operation as the M8000

"There's no significant difference in performance compared to the older XT M8000 models. However, the cable routing to the rear caliper is now better integrated with the frame (running seamlessly along it), making it both more aesthetically pleasing and more functional." I recommend this product, even though, as with the older models, I would have liked a bit more bite."
