...

When only the very best will do. This directional chain uses specific designs for the inner & outer plates to give the smoothest shift & best power transfer available. Hollow pins & a chrome treatment ensure this chain is both lightweight & long lasting. Key

Features: Chain uses a directional design, inner & outer plates are shaped so as to optimise shifting & chain performance. The outer plate has been designed to reduce the chance of chain suck. The inner plate has been developed to provide better contact with the gears to make the chain quieter & stiffer under load. Hollow link pins & perforated inner link plates for greater weight savings. This chain is 10 speed compatible
- 5.88mm chain width & optimised for Shimano HG systems. A chrome treatment for link pins & heat treated rollers, pins & plates ensure long lasting performance. A zinc-alloy finish helps prevent corrosion & keep your chain looking smart. Weight: 252g (Manufacturer claimed). This chain is optimised for use with Dura-Ace, but will work with all Shimano 10 speed drivetrains. Please note this chain is directional & care should be taken when fitting to ensure it is on correctly.

Performance without compromise. Super lightweight 10-speed cassette with a rigid alloy carrier for excellent shifting even under the most demanding gear changes. Key

Features: 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 & increase rigidity. 4 largest sprockets are made from titanium to reduce weight without sacrificing strength. Sprockets are extensively cut away & drilled to further reduce weight without reducing rigidity. Nickel-plated finish offers hard wearing resistance to corrosion. Alloy cassette lock ring. For Super Narrow 10-speed HG chains. Weight: 163g (11-23T
- Manufacturer claimed). NOTE: CS-7900 11-27 & 11-28 cassettes require the use of RD-7900 or RD-6700 (rear derailleur).
