Fast and responsive indexed shifting is the result. The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimisation to achieve super-highly efficient shifting. Hollowtech II: Providing the best balance of stiffness, strength, weight and rotating performance, The concept of Hollowtech II technology is focused on producing a superior crankset which will maximise a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. Hollowtech technology is an ultra-lightweight hollow crankarm created by Shimano with the company’s own proprietary forging technology that also maintains rigidity.

  • Saving you £37

Strong and lightweight to cope with the demands of rigorous riding, this Eagle DUB chainset is designed to be durable and stiff, with every part of the crankset working together to ensure efficient and effective performance with every rotation. Utilising the aggressively toothed X-Sync 2 chainring, the aluminium-built spider keeps a superb hold on your chain and provides a smooth feel as you propel yourself to greatness. The 7000 series aluminium crank arms allow for explosive power transfer as you rise uphill and sprint along the straight, with the wider BOOST design chainline allowing you to make the most of your larger frame and tyres to push your off-road rides to the very limit. Technologies X-Sync 2: X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grime. DUB Technology: The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler, by better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.

Praxis Works Alba 1x10-11 Speed Direct Mount Chainset Chainsets
  • £69.99
  • RRP £149.99
  • Saving you £53

Deep in the hills of Santa Cruz, cyclists are met by a nasty, four-mile, 1800 ft. climb named Alba Road. This respected ascent was the inspiration for the Praxis Works Alba road chainset. With its shapely forged-alloy arms, M24 alloy spindle, LevaTime II X-Spider and chainring, the Alba is ready for anything. LevaTime X-Spider and Chainring This 1x10/11 speed chainset features a LevaTime II (LT2) X-Spider and chainring that's the product of years of relentless testing and tweaking. This all new LT2 X-Spider is even stiffer than the original generation X-Spider. With a new forging design to support the new LT2 5mm plate big rings, this direct mount model keeps things flex-free when it’s time to put the power down. One Shot Forging At Praxis Works, the primary reason it forges its chainring is that it allows them to create dramatically shaped teeth and ramping surfaces. The brand's “One Shot” forging process allows it to make these shapes, and at the same time, create a harder and tougher ring than the competition’s machined rings. Imagine for a second, you have a big hammer and you are hitting a cold block of metal trying to shape it. Now, imagine the hammer is the size of a car and when you swing that hammer you’ve got hundreds to thousands of tons of pressure behind it. It’s a very intense and difficult process that requires a great deal of tooling know-how. This manufacturing process happens to be the brand's specialty. M24 Bottom Bracket This chainset comes complete with a press fit M24/GxP bottom bracket for installing a M24/GxP spindle crank into a BB86 Road or BB90/BB92 MTN Frame. Praxis M24 bottom brackets have a 24mm Drive and a 22mm NonDrive Bearing. These are specifically made for use with Praxis M24 spindle cranks or SRAM GxP spindle cranks. A drive-side wave washer is used for preload of the bearings. This specific press fit M24 bottom bracket is made to be installed in a BB86 Road or BB90/92 MTN frame. Born and based in the cycling mecca of Santa Cruz, California, Praxis creates and manufactures some of the best bicycle parts on the globe.   Please note: Image is for demonstration purposes only, actual chainset contains an M24 bottom bracket.   Manufacturer's Part Numbers: 89222983 Black 40T 165mm 89222979 Black 40T 170mm  89222980 Black 40T 172.5mm  89222981 Black 40T 175mm
