Race after race, Zero wheels have become synonymous with excellence, quality, performance, reliability… and now tubeless too!The updated feature of the Racing Zero 2WF, as the name suggests, is the introduction of 2 Way Fit technology, so that they can be used with or without tubeless tyres. MoMag technology utilizes magnets in the wheel construction to guide the spoke nipples into place. This allows for an undrilled rim bed that is completely airtight without the need for tubeless tape.Ceramic USB BearingsThe aluminium rims have an inner rim width of 17mm (perfectly suited to 25mm tyres), a differentiated front and rear depth profile, 27mm on the front and 30mm on the rear. Ceramic Ultra Smooth Bearings (USB) in a carbon hub on the front and an aluminium hub on the rear offer an incredibly low friction coefficient.Updated Dark Reflective DecalsThe graphics have been updated too, with dark reflective decals for maximum safety when riding in low light conditions whilst maintaining a stealthy look in daylight hours. The Fulcrum Racing Zero C17 2-Way Fit Road Wheelset excels uphill and in mixed conditions, thanks to the renowned reactivity of the Racing Zero family.Features: Rim Material: Aluminium (6082, T6 Pre-Aged), triple milling, square milling Use: Road Axle Compatibility: Front: QR; Rear: QR Rim Profile Height: Low Rim Height: Front: 27mm; Rear: 30mm Rim Width: 22.5mm Tubeless Compatible: Yes Inner Rim Width (Channel): ETRTO 17C Braking System: Caliper rim brake Braking Surface: Aluminium braking surface, turned Tyre Type: 2-Way Fit (for clincher and tubeless) Tyre Size: 700c Spoke Count: Front: 16 (8 left - 8 right); Rear: 21, Two-to-one (7 left - 14 right) Spokes Material: Aluminium Spokes Profile: Aero, straight pull Nipples: Aluminium Front Hub: Carbon, Aluminium oversize flange Rear Hub: Aluminium, Aluminium oversize flange Bearings: USB ceramic bearings.

All this at the brand’s lowest price point ever means this is a product offering value for money, as well as high performance. This listing is for a complete wheelset, you can also buy the front and rear wheel separately. Lighter, Stronger, Faster The Zipp 303 S wheelset is intended to be versatile, equally suited to training and racing in a range of conditions. Whether you’re on the silky-smooth tarmac of Majorca, the bone-shaking pavé of Flanders, or the dusty plains of Kansas, these wheels cover them all. Boasting a 45mm-deep rim, coupled with a respectable total weight of 1530 grams, these wheels offer a great balance between aerodynamics and weight, ensuring you have the speed on the flats and the low weight needed for when the road tilts up. As a wheel intended for racing, this product is expectedly stiff, and you’d be hard pressed to notice any lateral flex under those big, decisive accelerations. Additionally, even the most weight conscious can rest assured they won’t be held back on the climbs and that they’re responsive enough for sprint finishes on the road — whether that finish line is a sanctioned road race or the café, it doesn’t matter! Bigger, Wider, Faster Known as pioneers in the wheel-building space, Zipp are on trend in terms of offering wider tyre options. With wider tyres you can run lower air pressures, which can increase comfort and grip in the corners; importantly, this amounts to more speed, particularly across rough terrain.

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.
