High performance 10-speed Road cassetteHyperglide sprockets have a computer designed tooth configuration with contoured shift gates resulting in a crisp smooth shift even under loadClose ratio gearing allows a more efficient use of energy through finer cadence controlThree largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigiditySprockets are cut away and drilled to further reduce weight without reducing rigidityNickel-plated finish offers hard wearing resistance to corrosionChrome-plated steel cassette lockringFor Super Narrow 10-speed HG chainsWeight: 235 g for 11 - 23T
Lightweight 10-speed cassette with rigid alloy sprocket carrier for reduced weight and better shifting performance even under the most demanding gear changesHyperglide sprockets have been designed to reduce weight with improve teeth shaping providing accurate shifting and reduced wearWide gear range to meet the demands of all types of riderWeight 208 grams (11-23 teeth)
Super Narrow Hyperglide (HG) series 10-speed compatible directional chain recommended for Tiagra 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 For use with double chainset only 5.88 mm chain width optimised for 10-speed Super Narrow HG drivetrains Corrosion-resistant grey finish on outer plates 116 links 277 grams (114 links)
