Brakes/Levers/Pads

- (IS): 6-bolt/44mmBCD International Standard, (CL) 35mm CenterLock spline-mount - All rotors include hardware: either 6-bolt or CenterLock lockring+washer (lockrings for thru-axle applications available separately) - RT99 Centerlock rotor optimized for pure gravity. Takes the innovative 3-layer clad rotor to the next level by adding radiator fins. Braking and performance benefits include 20% less brake fade, 20% increase in stopping power and 20% longer pad life - RT98 CenterLock rotors are for XTR applications and utilize a bonded steel-over-aluminum "Ice Tech" design with an aluminum spider/carrier for decreased weight and improved heat dissipation (replacing RT97/96 versions) - RT76 6-bolt rotors can be used with all Shimano disc brake systems: XTR,Saint,XT,SLX,LX,Deore,etc. (note: the newer RT76 rotor uses a lightweight 2-piece design with a 5-arm aluminum carrier and a stainless steel rotor) - CenterLock lockring/washer applications: (QR) for quick-release hubs, (TA) for thru-axle, and (F or R) for front or rear when applicable

• 107mm arch for better clearance with mud guard • Updated rubber boots secure attachment to lead pipe • Strong braking power with excellent braking control • Cartridge shoe holder • Color options: Black, Silver

Shimano's disc rotors provide a sturdy and reliable braking surface to slow you down. The design is optimized to clear mud and dirt from the system for all-conditions braking. Continuously cooling itself, this rotor helps keep brake power consistent and improves pad life.

Shimano's BR-R451 Road Brake Calipers feature a sleek, minimalist design while providing excellent stopping power when you need it. - Compatible with STI and brake levers that are Super SLR enabled (Dura Ace Di2 7970, Dura Ace 7900, Ultegra Di2 6770, Ultegra 6700, 105 5700, Tiagra 4600) - Light action and accurate brake power - Adjustable toe-in brake shoes - Use of these calipers with standard SLR enabled STI and brake levers results in a "mushy" brake response - Brake Lever Actuation: Short Pull Super SLR - Brake Mount Type: Mid Reach Caliper (47mm - 57mm) - Brake Position: Front - Defined Color: Black - Pad Type: Cartridge

Shimano's Deore XT Ice-Tech rotors utilize the industry standard 6-bolt mounting system for secure mounting. These rotors use an aluminum core with steel outer plates to better control the temperature of the braking surface. This means quieter braking and, more importantly, less fade on long downhills and improved pad life. The various sizes give you total freedom of choice over the delicate balance of power versus weight.

The Shimano GRX BL-RX812 in-line brake lever delivers greater rider control for mixed-terrain riding thanks to Shimano's category-leading hydraulic disc brakes. The hydraulic disc sub brake lever offers reliable and accessible braking in more positions and allows for quick access while riding upright on the tops of the handlebar. - Quickly brake when riding upright - More confident and accessible braking from multiple positions - Less fatigue on long tours

With a focus on reduced weight and cross-country tuned stopping power, Shimano SLX M7100 brakes provide intuitive modulation so that you can explore your limits with confidence. The BL-M7100 levers feature an optimized lever axle position, an additional handlebar contact point for greater stiffness, and refined ergonomics for rider comfort. At the caliper end, the BR-M7100 2-piston caliper provides lightweight braking performance and is combined with quicker piston retraction. - 10% stiffer than previous generation M7000 even under high-temp conditions - Quicker brake engagement with shorter free stroke - Tool-free lever reach adjustment - I-SPEC EV Clamp Band enables optional integrated shifter setup

Shimano Deore hydraulic disc brakes are a solid setup, offering reliable power and rigid brake design for all riding styles, from XC to trail. The BL-MT500 brake levers deliver high-powered Servo Wave performance for rapid initial pad contact, along with I-spec II compatibility. These are paired with powerful 4-piston MT520 calipers that help boost rider confidence and enjoyment. - Highly responsive braking power for greater control and modulation - Sleek and durable master cylinder design - 4-piston calipers provide a wider pad contact area - Heat insulated pads and pistons

The Deore XT M8100 hydraulic disc brake is designed to provide high performance braking for a variety of MTB riding styles. Includes the brake lever and disc brake caliper. - BL-M8100 features a stiffer brake lever design that provides added support for aggressive riding - Servo Wave Action technology means quicker brake engagement with shorter free stroke - The BR-M8100 2-piston brake caliper is optimized for cross country riding styles - Includes finned metal pads and hose - Brake Caliper Type: Post Mount - Hydraulic Hose Length: 1000mm (Front) / 1700mm (Rear) - Hydraulic Fluid Type: Mineral Oil - Rotor Included: No - Pad Compound: Metallic
