Updated, refined, and ready to dominate smooth ribbons of singletrack, Shimano's XT BR-M8100 Disc Brakes hit the trail once again with their light weight, sleek aesthetics, and unbeatable stopping power. While a lot of the composition of the brake stays true to its predecessor, the 8000-series brake, like its two-piston design, integrated master cylinder, and clean black aesthetic, it features a redesigned brake lever based on the XTR 9100 series that's optimized for refined ergonomics, allowing you to test the limits with confidence and control. And along with this improved bracing angle, its new mounting design pairs up with I-Spec EV to save you space in the cockpit, so you've got plenty of room for dropper posts, remote lockouts, and accessories. The new XT 8100 brake lever packs in 10% more stiffness than the 8000-series, even under high temperature, this translates to quicker brake engagement, while the new mounting position makes for shorter free stroke.

What this translates to is a drastic increase in efficiency and control over the bike, without limiting brake engagement. Additionally, the lever stays the same over all of the 8100-series brakes, so you can maintain identical cockpit comfort from your rowdy enduro whip to your cross-country race machine. Servo Wave technology comes into play here in order to adjust piston travel relative to lever travel. As you squeeze on the brakes, the gap to the rotor quickly closes, then slows to permit predictable modulation. This allows the pads to sit further from the rotors at rest for less chance of drag. The calipers house a 22mm ceramic piston for inspiring stopping power, and Shimano uses a banjo fitting for the hose attachment at the caliper. The calipers also employ Shimano's Radiator Pads that have integrated fins in order to dissipate heat and to reduce fade on long, hot descents. The Shi...

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
