This frameset includes frame, forks, seat clamp, gear hanger and cable guides. Full carbon and UCI accredited, the Vitesse EVO Carbon Rim Brake Frameset delivers top-end performance and is equally as comfortable at the sharp end of the peloton as it is covering 200km sportives, and long days in the saddle. High Modulus Full Carbon Frame The Vitesse EVO Carbon Rim Brake Frameset features a lightweight T700 HM-UD carbon construction with tubesets that are optimised for the perfect balance of power transfer without a detraction in comfort. The oversized downtube features a squared profile to maximise stiffness and power transfer, the 386EVO bottom bracket and oversized chainstays improve lateral stiffness to ensure every ounce of energy is transferred from the rider to the rear wheel. Slender seatstays, a profiled top tube and a 27.2mm seatpost (seatpost sold separately) provide greater rider comfort with reduced fatigue. Agile and Dependable Full Carbon Fork A tapered headtube increases front-end stiffness and the matching T700 HM-UD full carbon fork with tapered steerer adds increased stiffness with impeccable handling and steering precision. Internal cable routing further improves aerodynamics and offers clean, uncluttered lines for improved aesthetics. Compatible Headsets and Bottom Brackets (BB): Prime headset here.

Campagnolo Record 12 Speed Hydraulic Disc BrakeDelivering increased power, greater ergonomics and an easier-to-maintain set-up, this 12 speed hydraulic disc brake is engineered for complete control in all road cycling situations. Benefitting from many of Campagnolo's finest technologies including Vari-Cushion, One lever-One Action, AMS Adjustment and an Ultra-Shift System, this model also offers a wide range of features and personalisation, so riders can fine-tune their braking and shifting performance to match their riding style or the terrain conditions.12 Speed Ergopower Record Disc Brake ControllerThe mechanical controller for the Ergopower Record 2x12 Speed Disc Brake offers an ergonomic, comfortable and safe support and grip thanks to Vari-Cushion technology, essential for those who stay on the saddle for several hours. Campagnolo has also equipped this model with its renowned One Lever-One Action technology, which assigns each lever a single function to prevent shifting errors. Another highlight is its Ultra-Shift mechanism, which enables upshifting up to three sprockets at a time and downshifting a full five. This function allows you to maintain cadence even in case of sudden changes of incline or rhythm, with speed and ease.Delivering more customisation, this lever adapts to different hand sizes with three levels of Reach Adjustment that enables riders to move the brake lever closer to the low grip. This makes it a great choice for any hand size, including smaller hands. In Addition, its AMS Adjustment allows braking modulation the moment of shift engagement through the use of specific levers. The carbon fibre brake levers feature a unidirectional disposition of the fibre to ensure they match seamlessly with the other components of the Record groupset (available separately).Campagnolo CaliperThe flat-mount Campagnolo brake caliper ensures powerful, modular braking in any situation owing to pistons measuring 22mm in diameter. The pad return is now optimised to ensure that there is no friction when the brake lever is released. A special metal plate positioned between the pad and the caliper piston cushions the vibrations during braking.The Campagnolo brake caliper is designed to be mounted together with the disc chosen by the rider (available separately) and to always guarantee the highest level of performance. Careful attention was given to making maintenance and assembly operations easy: the pads have wear indicators and replacing them is facilitated by the absence of physical return springs. Additionally, work was done on the insertion of the disc in the caliper to make changing the wheel easier and faster.Features: Brake Lever Material: Carbon Fibre Use: Road Speed: 12 speed Controller Technologies: One lever-One action, Ultra-Shift System, Ergopower Control Caliper Technologies: Standard Flat Mount, 22mm pistons in phenolic resin, Piston-caliper connector, Interchangeable spare parts, Wear indicator Comfort: Vari-Cushion hood Adjustment: 3 levels of reach adjustment Ultra-Shift System: Up to 5 sprockets in downshifting, up to 3 in upshifting Single or Pair: Single Weight: 463gTechnologies: Controller Technologies Comfortable Body: The controls enable a solid, safe grip when pedalling out of the saddle or gripping high on the handlebar. Rapid Shifting: Immediate shifting engagement enables activating the front derailleur with minimum effort and in any hand position on the handlebar. Multiple Action: An unplanned ascent, a sudden jerk: it takes barely a moment to find the right ratio owing to the multiple action of the controls. Ergonomic: The shape of the body and the possibility to adjust the reach enable all cyclists to use these controls, regardless of the size of their hands or fingers. Customisable: 3 levels of reach adjustment. Upshifting Lever Integration: More space under the control body when gripping the Ergopower control. Disc Caliper: Flat mount disc only, to be compatible with the latest frame technology. Maximum Smoothness Cables: Updated cable set maintains exceptional smoothness far beyond those of the competition, maximum performance longevity. Superior Alignment: Braking lever pivot aligned with slant of ergo power, more efficient power transfer requiring less energy from rider's hand. Upgraded Brake Lever: The result of meticulous studies (double curve brake lever, updated form outward curve). Vari-Cushion Hood: Different thicknesses allowing for greater grip, comfort and water dispersion. Enlarged Shifting Paddles: For instant reaction access.

OVERVIEW “AC-2” = Dual Angular Contact. This describes the use of both angular contact bearings&and&angled bearing cups/hub bores used in the hub design. The AC-2 hub features revolutionary bearing installation and function never seen before in a bicycle hub. It has been designed from the ground up for ease of maintenance and optimal bearing performance. The AC-2 Cassette Hub also offers changeable pawl/spring configurations for varying points of driver engagement to suit a rider’s personal preference. HERE ARE A FEW KEY POINTS OF THE AC-2 BMX DISC BRAKE CASSETTE HUB: -The AC-2 hubs use 20mm Angular Contact bearings with a wave spring pre-load. Bearings are pressed into tapered cups that mate with the angled bores machined into the hub shell. This design feature allows bearing/cup to be easily installed and removed from hub shell&without&any special tools. No more presses or hammers needed! Another attribute of the tapered bearing cup/angled hub shell bore design is how the bearings seat in the hub. The bearings/cups on each side of the hub shell are in&perfect&alignment with each other! This ensures superior bearing performance and less chance of premature wear. -Hub shell and driver literally “float” on the axle. The only force on the bearings is supplied by the wave spring(which delivers the appropriate bearing pre-load needed for angular contact bearings). Tightening of axle bolts has absolutely no affect on the bearings! -The bearings, wave spring, and shim(s) are secured on the axle by one retaining ring. The only tool used to assemble/disassemble the AC-2 hub is a pair of snap ring pliers! -The AC-2 hub cassette driver is also unique. It allows for changeable P.O.E.(points of engagement). The hub driver comes standard with 6 pawls and springs. This option offers 96 P.O.E. -Maximum engagement. The other choice is to use just 3 pawls and springs. P.O.E. is reduced to 48 and minimal drag is achieved. This is a rider preference choice and both have a unique sound! -The proprietary Profile Racing 10 spline aluminum cassette body allows you to use Profile's standard steel, Elite, or aluminum cogs ranging from 12t to 18t. -ISO Standard 6 bolt disc brake mount.
