Campagnolo EKAR 13 speed Cassette

Campagnolo EKAR 13 speed Cassette • 13-speed. • Lightweight, efficient design • Strong, durable construction • Closer high gear spacing • Wider low gear spacing • 9-tooth smallest sprocket on two options • New lighter N3W driver body. • The 1x system works best for gravel, with the 13-speed configuration enabling that to work across a full range of gearing ratios – and what underpins that is the use of a 9-tooth sprocket. • The precise 13-speed Ekar is available in three gearing variants, reflecting the different specialisms within the diverse gravel scene, and each providing the smoothest gearing progression and the optimum delivery of range. • On all three options, single-tooth steps across the six smaller sprockets provide the most consistent cadence progression with smooth, efficient changes. • Gradually increasing wider spacing features on the larger half of the sprockets. • This delivers a natural riding experience and helps you get the best from your performance on testing trails and tough terrain. • The three options' more widely spaced top end provide the most compact set for loaded endurance events, and the longest for full-on adventure riders. • The bespoke cassette configurations are each paired with suitable – yet easily changeable – single front rings to provide maximum range, smooth steps and ultimate efficiency – and unlike 2x systems there is simply no wastage. • Two of the three cassette options feature a 9-tooth cog. Extensive comparative tests have demonstrated that the 9-tooth is as efficient as any 10 or 11-tooth sprocket on any system, with no additional friction across its narrow-wide teeth, so you don't lose any of the wattage you produce. • Each cassette is built on two blocks, split 4- and 9-sprockets for the configurations featuring a 9-tooth, and 3-/10-sprockets for the range starting with a 10-tooth. • For enhanced mechanical resistance, heat-treated carbon steel is used for the core of both blocks, and benefit from a nickel-chrome-satin surface treatment which reduces wear and friction, delivering the optimum durability for gravel riding. It sits on a new freehub driver body – called N3W – that features on the lightweight carbon Campagnolo Shamal wheelset, with a wide range of compatible wheelsets to follow. N3W is highly versatile, featuring the same groove profiles as the classic Campagnolo body, but 4.4mm shorter and lighter. • With appropriate lockrings and adaptors, N3W is also compatible with all current and forthcoming Campagnolo 12-, 11- and 10-speed systems, with retro-fit kits including readily available. • As all current disc brake Campagnolo HH12 wheelsets are N3W-compatible you can easily update your wheels ready to run them with Ekar – switching wheelsets is easy and quick! • Combinations: • Endurance: 9-36T (9-10-11-12-13-14-16-18-20-23-27-31-36) • Gravel Race: 9-42T (9-10-11-12-13-14-16-18-21-25-30-36-42) • Gravel Adventure: 10-44T (10-11-12-13-14-15-17-19-22-26-32-39-44) • Weight - 340 gr (9-36T)/ 390 gr (9-42T)/415 gr (10-44T)
