Smooth Round and Natural - The ethos behind Shimano 105 components. The 105 groupset makes pro-level technology more accessible to part time racers and fitness enthusiasts. From the shifters down to the rear derailleur this groupset borrows from its big brother Dura-Ace. The shifters feature the new internal routing for the cable outers and the complete weight has come down to 2481g (Manufacturer claimed). Key Features: Shifters: Shift cables are routed under the bar tape: re-development and positioning of the internal mechanism provides a faster lighter and smoother shift. Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes. Brake lever pivots have been positioned to increase power and improve ergonomics when
riding on the hoods. Tunable reach adjusters enable custom fitments for all hands. Comes complete with silicon greased cables to further reduce shift friction and increase service life. 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 the CN-5701 chains (included) for increased contact to provide greater efficiency and improved power transfer. Lightweight anodised SG-X aluminium chainrings for smooth and precise shifting. Front Mech: Wide link design 105 double front derailleur for increased rigidity and improved shifting response For use with 105 ST-5700 or Ultegra ST-6700 shifters only for optimum shifting performance Wide inner
link increased rigidityand takes front shifting performance to a new level especially under heavy load For 10-speed drivetrains Light action spring reduces effort required to actuate shifts Maximum capacity of 16 teeth with 50-56 tooth outer The aluminium parts arecoated to resist corrosion and maintain their great looks Rear Mech: 10-speed 105 wide link rear derailleur short cage - SS Advanced Wide Link design increases rigidity and shifting performance Super stiff for fast and accurate changes across the cassette Large 11 tooth pulleys increase service life and reduce noise Super light shift action Compatible with 8 9 and 10-speed drivetrains Maximum low sprocket 30T Maximum front difference 16T total capacity 34T Average weight 221 grams Brakes: The racers choice 105 brake callipers
come in a compact and lightweight design for high performance Compact Super SLR Dual-Pivot design provides superior brake performance and light action Must be used in conjunction with ST-5700 ST-6700 or ST-7900 STIs for correct leverage ratio Enhanced brake arch proportions give a quicker linear response and increased power Low profile outer cable stop position improves cable routing for reduced friction Cartridge brake shoes for easy replacement Convex washers on the brake shoes offer toe-in brake adjustment and easy alignment Lightweight aluminium construction with an anodised finish to preserve the good looks 49 mm drop Chain: Super Narrow Hyperglide (HG) series 10-speed compatible directional chain recommended for 105 drivetrains Chain uses a directional design with specifically shaped
inner and outer plates to optimise shifting over the chainset and cassette Outer plate design has been developed to reduce the chance of chain suck The inner plate has been developed for better contact with gears providing smoother shifting under high load giving efficient pedalling increased rigidity and near silent running Durability is assured through a chromising treatment on link pins and the heat treatment of rollers pins and plates For use with double chainset only 5.88 mm chain width optimised for 10-speed Super Narrow HG drivetrains Corrosion-resistant grey finish on inner and outer plates 116 links 280 grams Cassette: High performance 10-speed 105 Road cassette Hyperglide 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 10-speed HG chains Groupset includes: Brake set BB cups Cassette Chain with joining pin Chainset STI Shifters Front and Rear derailleurs and cables. Chain has a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette. Weight: 2481g (Manufacturer claimed). Cassette ratio: 12/25. Chainring ratio 53/39. BB cup thread:
British. Comes with cables and outers. Please take care to choose the correct crank arm length when selecting your groupset.
