Lightweight HollowTech 2 105 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 2 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
A perfect companion to the SHIMANO 105 R7000 groupset the R7000 cassette is available in a wide range of road and mixed surface ratios. It is compatible with HG-EV and HG-X11 chains. High performance HG-EV 11-speed 105 Road cassette Hyperglide EV sprockets have a computer designed tooth configuration with contoured shift gates resulting in a crisp smooth shift even under load Close ratio gearing allows a more efficient use of energy through finer cadence control Largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity Sprockets are cut away and drilled to further reduce weight without reducing rigidity Nickel-plated finish offers hard wearing resistance to corrosion Pearl-bright steel cassette lockring For Super Narrow 11-speed HG-X chains
Wide link design 105 double front derailleur for increased rigidity and improved shifting responseFor use with 105 ST-5700 or Ultegra ST-6700 shifters only for optimum shifting performanceWide inner link increased rigidity and takes front shifting performance to a new level especially under heavy loadFor 10-speed drivetrainsLight action spring reduces effort required to actuate shiftsMaximum capacity of 16 teeth with 50-56 tooth outerThe aluminium parts are coated to resist corrosion and maintain their great looks
