Campagnolo EPS Record 11sp Ergopower Road Shifters - Black - Pair - Front & Rear}, Black
  • £293.99
  • RRP £349.99
  • Saving you £16

Campagnolo EPS Record 11sp Ergopower Road Shifters EPS Ergopower controls represent the direct "electronic" evolution of the well-proven mechanical Ergopower.Maintaining the special features, unaltered, the operating philosophy (one lever one action), Campangolo's trademark click feeling, Multishifting technology for the rear derailleur lever, the excellent ergonomics, the comfort of the brakes and the extreme braking efficiency.Features: The Mode Key: In addition to the 3 classic levers, the EPS Ergopower controls are equipped with what is known as a MODE key. By pressing on it briefly you can view the battery charge level, whereas by pressing on it longer you will enter adjustment mode without ever taking your hands off the controls. Comfort: The shape places the levers in a position that is easy to access at all times, without any effort at all, regardless of the steering position and whatever the size of your hands. By studying the positions of cyclists' hands, in fact, there were found to be 3 different riding positions depending on the route and riding style itself. These studies made it possible to create the special and exclusive shape of the EPS Ergopower controls, which unlike the mechanical controls, are equipped with a dedicated hood and the control body is made from a very new material that is more rigid and lighter. Effective Braking: The Ultra-Shift(TM) shape of the levers, as with the mechanical controls allows you to act on the brakes more powerfully. When you have a high grip on the handlebars, especially, it is possible to put the brakes on with more power and faster. Click Feeling: The levers simulate the classic Campagnolo Click Feeling thanks to the application of MultiDome technology. DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation. Multi-Shifting: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclist. Zero Settings: The procedures to reset the rear derailleur and derailleur to zero are essential for the system to function. Riding Settings: The client can adjust the reference position of the rear derailleur and/or derailleur using the adjustment procedure known as Riding Setting. One Lever - One Action: The EPS system CONTROL levers are positioned and act according to the same logic as Campagnolo mechanical gear levers. E2 Ergonomy: The design of the body of the control conforms perfectly to your hands. Water Proof: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes. WARNING - All connection, installation, removal and adjustment operations of the EPS drivetrain must only be carried out by a Campagnolo Service Center, a Campagnolo Pro Shopor a mechanic specializing in the installation of EPS systems. Any Tampering with or incorrect or incomplete installation of any part of the EPS system will automatically void the warranty. NOTE FOR SPECIALISED MECHANICS - Please remember that all assembly, disassembly, adjustment and maintenance procedures for the EPS drivetrain are described in the EPS technical manual, which is available in PDF format on our internet site www.campagnolo.com.

SRAM Red WiFLi 10sp Rear Derailleur - Black - Silver - Medium Cage}, Black - Silver
  • £291.00

SRAM Red WiFLi 10sp Rear DerailleurThe SRAM RED Rear Derailleur has been designed to deliver the performance advantage you‘ve come to expect from SRAM. With WiFLi, the rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette.The new range of gears is wider than the standard triple chainring system and saves well over 250 grams.We‘ve paid rapt attention to the finer details, like adding a hollow titanium anchor bolt and even refining tooth geometry of the jockey wheel. The result is that the chain runs through the new RED Rear Derailleur smoother and quieter than ever before.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 we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize 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™ = Wider - Faster - LighterSRAM's WiFLi™ Technology is based on the compact 2 x 10 - two front chainrings and 10 gears in the rear - design inherent in SRAM Apex and Rival, which delivers a wider range of gears than your standard triple, faster shifts through two chainrings and 10 gears, and with significant weight savings. It's the newest technology from the company that continues to innovate the cycling experience.Features:Wider – a wider range of gears for every climb and any descentFaster - two chainrings shift (and set-up) much faster and more easily than threeLighter – as much as 274g (9.8%) less than the most popular road tripleMuch improved Q-factor - improved heel clearanceEasier set up - two is easier than threeCompatible with SRAM Red, SRAM Force, SRAM Rival and SRAM ApexExact Actuation shifting provides fast, accurate shifts32T clearance thanks to the mid cage design: widest gear range availableNew silent shifting with optimized AeroGlide lower pulley, ceramic bearingsNew spring-fixed barrel adjusterNew chain pulley cage adds precise chain managementTitanium pinch bolt keeps a low profile while minimizing weightSpeeds: 10sMaterial: Carbon Inner Links, Carbon Cages, Aero Designed Titanium HardwareWeight: 167gCompatibility: 32T max cassettesCage Sizes: Mid cageBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
