Shimano Deore M410 Disc Brake (M4100 Lever)The Deore M410 Disc Brake (M4100 Lever) from Shimano is for the avid mountain biker who wants a reliable hydraulic disc brake that delivers ultimate control and safety in all riding conditions.Shimano M4100 Brake LeverThis brake lever is engineered for fast-paced MTB riding, as it gives you exceptional stopping power and control on the toughest of rides. It features a rock-solid alloy construction, which makes it capable of handling all the sudden hits that come with weaving between the trails at speed. Shimano has also equipped this model with an adjustable lever reach, so you can set it up to perfectly match your hand size, personal preferences and the trail conditions. Shimano Deore M410 Disc Brake CaliperReady for intense mountain bike adventures, this brake caliper delivers smooth and efficient braking with a minimalist design. It features a one way internal fluid circuit, which makes bleeding easy, while great piston retraction increases pad to rotor clearance. Shimano has also ensured that this post most model is Ice Tech compatible, so it can be used with Ice Tech pads (sold separately) for greater heat dissipation, reducing brake surface temperature by 50 degrees Celsius. Ice Technologies for All Conditions RidingThe fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. Ice Technologies piston in order to achieve optimized lightweight, high rigidity and heat dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss. One Way Bleeding“One Way Bleeding” was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

SRAM found that in their systems DOT 5.1 takes almost three times longer to boil than DOT 4, thus allowing flawless, fade-free performance in even more extreme conditions.Expandable Bladder: SRAM's new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it's needed. The result is improved backpressure relief, which produces dependable braking power and consistency.PiggyBack Reservoir: The brake fluid reservoir on SRAM's latest lever design is optimised for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement.Timing Port Closure: A hydraulic brake's timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurises the system. SRAM's new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store."
