Prime BlackEdition 38 Carbon Wheelset An all-round beast of a wheelset, the BlackEdition 38 Carbon Wheelset is designed for those looking to ride whichever terrain they want to tackle, without giving away any handling or stability. With a greater strength to weight ratio due to the R010 CNC machined 6061 hubset and DT Swiss straight pull spokes, this T700 UD carbon fibre wheelset is stiffer and in turn more reactive. The 38mm deep, 27.5mm wide rim creates a more linear contour with the tyre, which increases aerodynamics and decreases rolling resistance, essential for saving vital seconds. But, that's not all, Prime has upgraded it to a higher grade of carbon, saving 40g per rim, making the new BlackEdition the lightest and stiffest rim yet. Complete with a collection of spares in the box, the BlackEdition 38 Carbon Wheelset will confidently take on any road or Cyclo-X terrain. Shave The SecondsIf you're looking for an upgrade to shave the seconds away, the Prime BlackEdition 38 Carbon Wheelset is the wheelset you need to tame any terrain. Since the release of our BlackEdition rims in 2018 we've been working hard behind the scenes with the Vitus Pro Cycling in search of the marginal gains that could push them onto the podium in some of the UK's biggest races. We've experimented with numerous types of resin and tested countless new lay ups before we settled on our new and improved BlackEdition rim. But, that's not all, we've upgraded to a higher grade of carbon, making the new BlackEdition our lightest and stiffest rim yet.

Sector CT30 Carbon Cyclocross WheelsetDesigned in partnership with wheel industry expert, Paul Lew, this CX wheelset features a unidirectional carbon fibre rim construction that gives it phenomenal strength without sacrificing any weight. Sector has also equipped this wheelset with a 30mm deep tubular rim profile that provides the ultimate blend for weight, mud-shedding ability, stiffness and aerodynamics. Sector has custom designed the carbon CT30 laminate and impact performance within their existing tooling to meet the specific requirements for use as a Cyclo-Cross disc brake rim. This will ensure your wheels will withstand multiple seasons of brutal Cyclo-Cross races.Cyclo-Cross puts a demanding amount of torque on the rear hub, often in very muddy and wet conditions. Into the CT30 we have laced a rear hub with a four-pawl ratchet and oversized pawls to ensure engagement never fails. Both front and rear hubs are fitted with high quality double sealed bearings to keep the worst of the mud out. The lightweight 7075-T6 Aluminium alloy hub shells feature angled flanges to ensure that they follow the path of the spoke, reducing the stress on the spoke and increasing its lifespan.Features: Rim Material: T-700 Unidirectional Carbon Fibre Wheel Size: 700c Use: Cyclocross Spokes / Type: Pillar 1416 DB / J-Bend Nipples: Pillar Pro Alloy Hub Rotor Fitment: Centrelock Freehub: 4 Pawl, Shimano HG) Hole Count: 24h Rim Width: (Internal) 24mm | (External) N/A Rim Depth: 30mm Tubeless: No Single or Pair: Pair End Caps: (Front) 100x12mm / (Rear) 142x12mm Extras: QR End Caps Weight: 1400gBuy Sector Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
Sector R26 Road WheelsetThis road bike wheelset features a robust aluminium construction, which makes it ideal at withstanding all the abuse that's associated with unpredictable riding conditions. Designed to transform the feel of your bike, this wheelset includes a CNC hub, Pillar Wing Spokes and mid-depth aerodynamic rims, which stand up to the brutality of all riding conditions, while increasing the feel and performance of your bike. It Starts in the MiddleThe responsive feel of this Kinesis wheelset begins at the hub. The R26 features our lightweight CNC hub that maximises stiffness and torque transfer, with angled flanges that follow the path of the spoke, ensuring stress is kept minimal at this critical junction. Inside, we've used Revo Cream bearings for miles and miles of smooth-spinning performance. Wing PowerThe R26 road bike wheelset is built with the Pillar Wing Spoke. Unlike regular flat bladed spokes, the Wing Spoke features an ovalized profile inspired by the nose cone of a missile. This addresses several issues that are present with flat bladed spokes. Firstly, flat-bladed spokes are optimized for a fully laminar airflow coming directly from the front. In the real world, airflow is turbulent and from many directions. The Pillar Wing profile is aerodynamic through different yaw angles. The second advantage of the Wing spoke lies in the bigger cross-section. The thin nature of flat bladed spokes means that sideways deflection is high. Furthermore, they fail to adequately deal with braking forces generated from the hub, such as the case with disc brake bikes. Thanks to the Pillar Wing Spoke the R26 road wheelset is stiff when sprinting and cornering, and extremely responsive under braking and acceleration.The Rim is All RoundThose that have been unfortunate enough to ride a deep section aluminium rim know all too well that they are heavy, stiff, and jarring. Any aerodynamic advantage that such a rim offers is offset by the lack of vibration damping, which ironically fatigues you faster and slows you down.By contrast, the R26 wheelset features a tubeless-ready rim that is 26mm deep, occupying the sweet spot between aerodynamics, ride quality and weight. The large 19.5mm internal width works great with everything from 23mm to 36mm tyres, but especially well with tyres in the 28 to 32mm range, which is quickly becoming the de facto choice for anyone not riding on the track.Features: Rim Material: 6061-T10 Aluminium Use: Road Spokes: Pillar Wing Aero / Straight Pull Hub Rotor Fitment: Centrelock Freehub: 11 Speed, 3 Pawl, Shimano HG.

Sector GCi Carbon Gravel WheelsetWhether you're racing across the mud or simply exploring the countryside gravel roads, this wheelset is engineered for fast and smooth-rolling performance. It features a hard-wearing unidirectional carbon fibre rim construction, which allows you to benefit from its amazing strength without adding any unnecessary grams to your gravel bike. Engineered to excel in high impact environments, this model is equipped with revolutionary TeXtreme Innegra that's integrated into the layup of the rims. This special fibre delivers 75% high impact resistance when compared to standard carbon rims of the same profile. This means you can enjoy high energy rides with superior vibration damping and none of the harsh stiffness associated with carbon.So what is Innegra?Innegra is a fibre derived from polypropylene that exhibits some highly beneficial properties, including high strength-to-weight ratio, resistance to damage, vibration damping and energy dissipation. The TexTreme fabric used in the layup of GCi rim is a Spread Tow fabric built from a hybrid of Innegra and T700 carbon fibres. The Spread Tow layout is significant because it also contributes some positive attributes - the fibres are straighter (reduced crimp therefore higher strength) and it facilitates the use of less resin (lower weight).In the GCi rim the Spread Tow fabric is used on the outer layer of the rim, giving it the unique checkerboard pattern.Sounds good, but what does that mean for a rim? Significantly more compliance...Under a lab test the GCi rim was 50% more vertically compliant than a unidirectional T700 carbon rim of the same profile. This test involves loading the rim with a 100kg weight, in which the GCi rim exhibited a deflection of 15.74mm compared to 10.55mm on the standard T700 rim.It is widely acknowledged that vertical compliance is important for damage reduction (less likely to crack), a reduction of fatigue and to improve traction. Such an improvement in vertical compliance also brings a radically improved ride quality to the GCi wheelset.The Innegra equipped rims do not have the associated harsh stiffness of regular carbon wheels. Significantly more impact resistance...In the lab the GCi rim was able to handle impacts of almost double the standard required for MTB wheels by the UCI. The GCi rim withstood an impact of 140J compared the UCI stipulated requirement of an 80J impact, making it 75% stronger than the UCI requirements. In real world terms, the GCi rim can handle the equivalent of dropping a 15kg weight from a height of up to 1.08 metres onto the bare rim, thus making it 18% stronger than a recognised leading competitor who has published their data. Much less weight...Despite offering strength and compliance advantages, the use of Innegra also allows the construction of an extremely lightweight rim. The Innegra equipped GCi rim weighs just 440g, and Sector's complete wheelset weighs just 1690g.Features: Rim Material: T-700 Unidirectional Carbon Fibre; Outer layer: TeXtreme Plain Weave Spread Tow Carbon Fibre and Innegra S Hybrid Wheel Size: 700c Use: Gravel Spokes / Type: Pillar 1422 Bladed / Straight Pull Nipples: Pillar Black Brass DSN Hub Rotor Fitment: Centrelock Freehub: 6 Pawl (Shimano or SRAM XD options available to select) Hole Count: 24h ERD: 566mm Rim Width: (Internal) 24mm | (External) 31mm Rim Depth: 38mm Tubeless: Yes Single or Pair: Pair End Caps: (Front) 100x12mm / (Rear) 142x12mm Extras: Tubeless Sealant, valves, tape and 15mm end caps Weight: 1690gBuy Sector Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
