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.

Campagnolo Chorus Ultra Torque Carbon Chainset 11Speed Chainsets
  • £322.99
  • RRP £432.99
  • Saving you £25

The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain. A completely new design, the Chorus EPS crankset represents increased rigidity as well as fresh and cutting edge aesthetics. Gone are the days of having a dedicated bolt pattern for standard chainrings and another for compact rings and no longer will changing from traditional to compact, or vice versa, translate into the obligatory purchase of a completely new crankset. The new bolt pattern allows for all 3 chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankset. Changing between compact and standard is now as easy as changing 8 bolts and two chainrings. While the new 4-arm bolt pattern makes for a much more practical design that offers the cyclist a more versatile component, the Campy Tech Lab was dedicated primarily on increasing performance characteristics. The new design incorporates a 8 bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity. In addition to completely redesigning the spider, Campagnolo engineers dedicated a great deal of energy towards a completely new crankarm that is a great deal stiffer than previous versions. Add this new highly rigid crankarm to the new four-arm spider design and you have a complete crankset that not only excels at transferring power more than any previous version but one that is also more versatile with respect to gearing.

  • £279.99
  • RRP £352.99
  • Saving you £21

Specifically tailored for the demands of road cycling, this 12 speed chainset comes kitted out with carbon fibre crank arms for the best balance of stiffness, durability and low weight performance. Thanks to this model's carbon fibre build, it delivers a smooth and responsive pedal stroke without adding any unnecessary excess grams to your ride.

Technically advanced thanks to unidirectional construction technology in carbon fibre, it is directly moulded without any surface coating and has an Ultra-Torque steel axle like the Record chainset. The revised 12x cranks are more versatile thanks to the bolt PCD of 123mm, giving it an extremely solid structure, also ensuring a wider variety of uses. The smaller bolt circle on the Chorus chainset makes it compatible with 36/52, 34/50 and the brand new 32/48 ratio chainrings (options available to select from the menu). Technologies: - The Q Factor remains the same (145.5mm): The widths and biodynamics of the stroke are the same. - Unidirectional carbon fibre cranks, steel axle and aluminium chainrings: Good stiffness and optimum power transmission. - Symmetrical teeth on the internal chainring: Fluid, precise transmission, even with extreme cross-chaining. - Optimised design for any chainring combination: Maximum performance, whatever the course style. - Double Fixing: Assembly of the large chainring onto the crank is secured by a ring of 123mm bolts, while the inner chainring is attached to the outer by way of 96mm PCD bolts. - Surface treatment of the chainrings for longer life. - 12x Chorus Ultra-Torque chainset for use with the disc or rim brake groupset.

Campagnolo Centaur Ultra Torque 11 Speed Chainset Chainsets
  • £164.99

It's also very versatile, as if you want to change from a 50/34t to a 53/36t or vice-versa, there's no need to change the entire crankset as the spider is compatible with either chainring combination. Smooth Performance The Centaur's chainrings have a special anti-friction coating to encourage smooth chain operation. The chainrings also feature Campagnolo's "MPS™" technology, which enables quick and accurate shifts no matter how hard your pushing and in all weather conditions. Also, thanks to the use of the "Ultra Torque™" bottom bracket system, you'll enjoy consistent, rigid performance and optimised power transfer. Technologies: MPS™ (Micro Precision Shifting System): Optimised design of the up-shift and down-shift zones and of the profile of the teeth – enables fast and precise shifting in all types of conditions. 8 chain upshifting areas and 2 chain downshifting areas result in faster and more precise shifting, even under stress. Ultra Torque System™: Six years after its introduction, this system is still considered the best performing crankset spindle in terms of stiffness, low weight and efficiency of power transmission. Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals. Furthermore, despite the narrow side profile, Campagnolo has been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter.
