Lightweight HollowTech II 105 11-speed chainset Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low The chainring teeth have been developed to work in conjunction with HG-X 11-speed chains for increased contact to provide greater efficiency and improved power transfer HollowTech II allows the bottom bracket bearings to be spaced wider apart, enabling the use of larger bearings and an increased axle diameter Can be used with Shimano external or press-fit bottom brackets The system allows for easier installation, adjustment, and maintenance Lightweight anodised SG-X aluminium chainrings for smooth and precise shifting
Precision-engineered high performance Dura-Ace hydraulic disc brake STI's give you control, modulation and power with minimal effort in all riding conditions Dura-Ace R9100 STI are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, and a titanium clamp band / fixing bolt Hydraulic brake lever provides excellent stopping power with less effort especially from the hood position Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear Shift cables routed under the bar tape using Polymer coated inner wires make for a smooth shift action, providing faster, lighter shifting Vivid Index shifting with short stroke to the release levers gives a quick and accurate shift Gear shift cables can either be routed round the front or rear of the handlebar to suit all rider preferences Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes Small volume ergonomically designed smooth lever hoods for added comfort Finely tuneable reach adjusters for the levers enable custom fitment for all hands Free stroke adjustment for pad to rotor contact setting Kit contains left hand bled ST-R9120 STI, BR-R9170 flat mount brake calliper with pads, hoses and mineral oil (without rotors or adapters) Weight: 505 grams per set
Super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durabilityOuter plate design has been developed to reduce the chance of chain suckSil-Tec surface treatment technology (PTFE plating) on inner links that is smooth running and increases durabilityThe inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near silent running5.62 mm chain width, optimised for 11-speed Super Narrow HG-EV drivetrainsAverage weight 257 gramsFor more information on how to keep your bike running smoothly, click here to see PBK's expert advice on taking care of your chains and cassettes.
Top of the range, high performance Dura-Ace low profile hydraulic road disc brake for efficient braking in all conditions. Key Features: Front wheel use for flat mount forks with adapter to flip between 140 and 160 mm Oversized 22mm ceramic pistons optimized for heat insulation, lightweight and stiffness Opposed 2-piston design reduces leading effect and optimal pad wear increases braking control Increased pad to rotor clearance reduces the chance of rotor drag Direct flat mount and open design allows easy and quick wheel replacement Forged calliper design is lightweight and rigid One way internal fluid circuit makes bleeding easy Mineral oil brake fluid is non-corrosive and less hazardous than conventional hydraulic brake fluid Shim-less mounting bracket allows for quick installation and setting up Recommended for use with Ice Tech FREEZA Centre-Lock SM-RT900 rotors for optimum braking performance Comes complete with resin compound aluminium radiation fin pad further improves heat dissipation reducing brake surface temperature by 50 deg C Inline hose routing for low profile design
