The 9170 shifters feature an ideal ergonomic shape that is comfortable in the hand and similar in size to mechanical braking versions of the shifter. The shift paddles now also feature a more defined "click" for confidence in shifting and to prevent mis-shifts. E-Tube compatibility means that the shift paddles can be customised to suit the rider. The 9170 shifters now include Synchro-shift technology that automatically moves the rear derailleur when the front ring is changed or moves the front derailleur with the rear shifts to optimise chainline and drivetrain efficiency. The 9170 brake calipers have been tuned to perform optimally in road racing conditions. They feature the Shimano Flat Mount system for a sleek and aerodynamic profile and Ice Tech pads for improved heat dissipation. This kit comes pre-bled and ready to use with shifter, hose, caliper and pads.
Built with an aerospace shell design and materials, Troy Lee were able to get the D4 Composite helmet to 1050 grams without sacrificing any strength. MIPS (multi-directional impact protection system) is used to add an additional layer of safety in the event of a fall. For comfort, the D4 Comp routes cooling air through a front air intake system that flows through the polymer centre and power grid side mesh keeping your head cooler during the ride. X-static and XT2 anti-microbial/anti-odor padding keep the inside of the helmet a much nicer place to be.

Wahoo Speedplay Nano Road PedalsWith a Carbon Fibre composite body and a titanium spindle, the Nano clipless pedals are the top model in Wahoo’s Speedplay range. Tipping the scales at only 168 grams each, these super-light clipless pedals are an ideal addition to any race-ready road machine.Adjustable FloatThese pedals feature an adjustable free float that can be fine-tuned to ensure you get the correct float movement, which reduces the cycling strain on your knees. Other pedals only allow a pre-set amount of float or no float at all, but the Zero pedals can be adjusted to your personal preference. This helps to ensure you will be comfortable even at the end of the longest days in the saddle, helps to avoid injury and significantly optimises your power output.Dual-Sided Cleat EngagementAnother invaluable feature is the dual-sided entry, which means you can just step down on the pedal and go. No more fumbling or looking down to get into the right position, as the cleat’s design and pedal’s shape ensure that you’ll engage quickly and safely without having to stop and think. Maximum Comfort & PerformanceUnlike traditional cleats, each of the essential foot positioning adjustments can be changed without affecting each other. Three-Way Adjustment ensures you can set up the cleat’s front/rear and side-to-side positions individually and then choose how much float you want. These unique adjustment settings significantly increase comfort and efficiency while dramatically reducing knee strain and fatigue. Cleat Covers Designed for Safer WalkingThese Zero pedals come with Speedplay's rubberised cleats, which make those off the bike periods less dangerous if your bike's mechanical problem forces an extended walk on the tarmac, or if you feel the need for a coffee stop.Features: Body Material: Carbon Fibre Composite Spindle Material: TitaniumSpindle Size: Standard 9/16” thread Bearings: Triple Sealed Cartridge & Needle Cleat Type: The Zero cleat fits any shoe with a three-hole or four-hole mount Cleats Included: Standard tension walkable cleats included Q-Factor: 53mm (alternative spindles available separately) Double-sided entry The Zero cleat positions your foot closer to the top of the spindle for improved power transfer The thin pedal profile of the Zero pedal lets you power through corners where your rivals coast Built-in grease port for easy bearing lubrication Manufacturer's Part Number: WFPRN1S53 Weight: 168g (each)Technologies: Large, Stable Pedalling Platform: The Zero Pedal System provides the same solid connection as conventional single-sided pedals, but with Speedplay's unique, inverted design the cleat provides the platform once the cleat in engaged Quality Without Compromise: Zero pedals use precision cartridge and needle bearings - three of them instead of two found in most other pedals - which allows the Zero to be thinner for a lower stack height, better cornering clearance, and reduced aerodynamic drag. Like all Speedplay Pedal Systems, the locking edges of Zero pedals and cleats are metal-on-metal for durability and safety, unlike competitors who use engagement edges made of plastic True Locking Mechanism: The Zero's locking mechanism does not rely on spring tension for security, so entering and exiting Zero pedals is easy, but unintended release is virtually impossibleBuy Wahoo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
