SRAM Red 11 Speed Road Rear Derailleur - Black - Medium Cage}, Black
  • £295.00

SRAM Red 11 Speed Road Rear DerailleurSRAM Red 11 Speed Rear Derailleur has been designed to deliver the performance advantage you have come to expect from SRAM. The derailleur is equipped with SRAM's Exact Actuation technology, which ensures precise and efficient shifting.SRAM have paid special attention to the finer details, like adding a hollow titanium anchor bolt and the use of their AeroGlide pulleys. The result is that the chain runs through the rear derailleur smoother and quieter than ever before.Features: Material: Carbon Cages, Carbon inner links, aero designed Titanium hardware Exact Actuation shifting provides fast, and accurate shifts More clearance with 28t cassettes thanks to a longer B-knuckle Medium cage (WiFLi version) compatible up to 32T cassette New silent shifting with optimised Aeroglide Pulleys with ceramic bearings New spring-fixed barrel adjuster New chain pulley cage adds precise chain management Titanium pinch bolt keeps a low profile while minimising weight Speed: 11-Speed Recommended Group: SRAM Red 11-Speed Weight: 145gTechnologies: AeroGlide Pulleys: New tooth pulley design with a sound damping effect for a super efficient and silent ride experience. Bottom and top pulleys benefit from this feature Exact Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement). Exact Actuation helps to simplify and stabilise the uneasy act of balancing rear derailleur hanger design, tight cog spacing, and exact cable tension. The result: the easiest index shifting system to set up—and it stays that way WiFLi (medium cage only): SRAM's WiFLi technology accommodates a wider range of gears than a standard short-cage road derailleur. Compared to a triple chainring setup, it provides faster shifts and significant weight savingsBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Shimano Ultegra R8100 12 Speed Chainset - Black - 50.34t}, Black
  • £299.99

Shimano Ultegra R8100 12 Speed ChainsetThe Ultegra R8100 12 Speed Chainset from Shimano offers efficient power transfer, smooth gear shifting performance and top-quality race-ready reliability. Ideal for competitive road racing, this chainset offers the optimal balance of stiffness and strength at a low weight. Plus, it features Hollowtech II crank arms, a Hollowglide outer chainring and is compatible with most modern bottom bracket standards from Shimano.Shimano's Ultegra FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. Spanning 160 to 175 mm in length, Ultegra cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms. An integral part of Shimano's new 12-Speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-Speed shifting, the Ultegra crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements. Hollowglide ChainringHollow technology on the outer chainring. The Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance. Hollowtech II Forged Crank ArmsA lightweight crankset not only reduces the bike's weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. Optimised Balance of Stiffness, Strength and WeightThe concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider's power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.
