Chainsets Info

Bolt on a new chainset - the chainrings, and the crank arms which turn them - to improve your drivetrain performance. Chainsets and cranks are increasingly specialised and, depending on which one you choose, can save weight, improve power transfer through increased stiffness, or just be plain stronger. For mountain bikes, there are the ever-popular Shimano models, alongside Raceface and FSA, so you can choose the right model for your type of riding. For roadies, there's have double chainsets - compact versions for sportive riders, and standard for racers - and triple chainsets for those wanting a wider variety of gears. There are special chainsets for single-speed bikes as well.

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

Truvativ Descendant 6K Eagle Boost DUB Chainset Chainsets
  • £104.99
  • RRP £109.00
  • Saving you £4

All set for hitting your local trails, this MTB chainset features two robust aluminium crank arms that have been put through SRAM's forging process for maximum strength and durability as you navigate around the mountain. Benefitting from an X-SYNC 2 Eagle chainring, it uses its aggressive 32 tooth design to deliver superior chain retention for a smooth, more efficient pedal feel. With a focus on long wear-life, the X-SYNC 2 Eagle design reduces friction and the accumulation of mud, grit and grime for dependable acceleration on the toughest of terrains. Coming complete with many of the brand's performance-enhancing technologies such as DUB and Eagle, as well as Boost spacing, this is a great choice of upgrade for powering your way from trail to trail. Boost Spaced MTB Chainset with DUB Technology The Descendant 6K crankset delivers consistent performance every time out. Featuring SRAM's X-SYNC 2 tooth profile chainring, the Descendant crankset is engineered for complete chain control. Each tooth's thickness is precisely toleranced and controlled to work seamlessly with the SRAM chain's inner and outer links. SRAM DUB technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability. - Optimised 6000 series forged aluminium arms. - SRAM DUB technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible. Technologies: Boost: Boost is the standard wheel and drivetrain specification that opens the opportunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, wider range of chainring options, as well as more clearance for bigger tires and wider, stiffer wheels. Eagle: Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains. X-SYNC 2: SRAM X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC 2 Eagle design reduces friction and the accumulation of mud, grit and grime. DUB: The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.  Manufacturer's Part Numbers: CW8532003 Black 32T 170mm CW8532002 Black 32T 175mm
