Shimano BR-R7170 105 Flat Mount Brake Caliper - Without Ro Disc Brake Callipers
  • £69.99

Ideal for pairing up with the Shimano 105 Di2 brake lever (available separately), this brake caliper offers 10% wider pad clearance than the mechanical 105 option, meaning less brake rub and less noise. It also brings a simpler, maintenance-friendly brake fluid bleeding process. Disc Brakes Optimised for Road Riding With proven hydraulic braking technology, the Shimano 105 caliper features the Shimano Flat Mount System and its low-profile design that is ideal for road bikes. More compact and lighter than ever, the R7170 brakes offer wide pad clearance for easy wheel removal and quiet performance as well as one-way bleeding for easy, clean maintenance. Ice Technologies The 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 the Ice Technologies piston to realise the cooling technology for consistent performance. 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. This model's Ice Technologies piston achieves optimised lightweight, high rigidity and heat dissipation. One Way Bleeding One Way Bleeding was developed for quick and easy prevention of air in the hydraulic system. Shimano has 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. Shimano 105 Di2 brings electronic wireless shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, Shimano 105 Di2 represents a transformation of the road cycling experience.   Technologies: - 10% wider pad clearance decreases the chance of disc brake rotor rub. - Maintenance-friendly bleeding process.   Manufacturer's Part Numbers: BRR7170F Black Front  BRR7170R Black Rear

SRAM Level TLM Disc Brake Disc Brake Callipers
  • £69.99
  • RRP £168.00
  • Saving you £58

The stunning sram level tlm model puts proven SRAM braking performance at your fingertips thanks to its sleek, lightweight design that's specially optimised for XC and light trail use. Additionally, it delivers power and modulation via its robust alloy lever blade, DirectLink actuation, DOT 5.1 fluid and a two-piston monoblock caliper. Furthermore, this superb design provides you with superior heat management for consistent, fade-free braking, ride after ride. Technologies: Bleeding Edge: Bleeding Edge technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimize air contamination and fluid loss. DirectLink: SRAM’s DirectLink lever design produces a solid, positive feel the second you squeeze the lever to engage the brake It offers a no-nonsense solution to give you precise control. DOT 5.1: Heat is an enemy of any brake system, so advancements in heat management mean advancements in your ride. We found that in our 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 back-pressure relief, which produces dependable braking power and consistency. Heat Shield: The stainless steel heat shields breaks the thermal connection between the pad and caliper body, reducing caliper fluid temperature by about 20C even in the most extreme testing conditions. MatchMaker and MMX Compatible: Save weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM triggers, and various RockShox controls, all with one tidy, light, clamp-a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker X integrates the RockShox®XLoc and is compatible with XX and X0 brakes. Standard Matchmaker is also available and works with any split-clamp design and RockShox PushLoc. PiggyBack Reservoir: The brake fluid reservoir on SRAM’s latest lever design is optimized 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 - so you can switch your levers on the handlebar and run them moto without hassle. 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 pressurizes 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.
