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.
Any offering from Zipp is certain to come with high expectations, and this version of the Zipp 303 S wheelset doesn’t disappoint. With this edition, the wheel building pioneers are touting not only the speed and low weight of their wheels, but also the durability and ability to fit wide tyres, making them suitable for on and off-road exploring. 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. Boasting a broader, hookless rim, the Zipp 303 S wheelset is optimised for a 28mm tyre on the road but will happily take up to 50mm tyres for gravel adventures. Stopping Power It has become almost the norm for wheels to come in disc-brake-only versions, and that’s exactly what you get here. Being equipped with disc brakes means that when you squeeze the brakes — regardless of the conditions — you can be confident you’ll get consistent stopping power. Lifelong Quality Filled with the highest-quality steel bearings, the hubs will run smooth and should stand the test of time.

Zipp 858 NSW Carbon Tubeless Rear WheelZipp's ultimate aero weapon is now tubeless ready. That means you get the many aero advantages of the 858 NSW Tubeless rim-brake rear wheel with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The rear wheels' 19mm internal width is optimised for running wider tyres at reduced air pressure. The 858 NSW's undulating 77/82mm-deep rim shape, the brand's proprietary Sawtooth profile, takes design cues from nature for Zipp's highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil nodes, that reduce both aerodynamic drag and side force. Simply put, the 858 NSW Tubeless is ideal for those focused on triathlon, time trials, or aggressive road riding.SawtoothSawTooth is the name given to Zipp NSW's patented variable depth 53/58mm rims. Developed utilising the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth utilising the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature's most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before. This patented new rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that works together with Zipp's new HexFin ABLC dimples for improved airflow. The result is Zipp's highest performing rear wheel ever realized with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind.ShowstopperZipp's industry-leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking.Axial ClutchWith Cognition's Axial Clutch technology, Zipp has reduced drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedalling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don't require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism, Zipp uses magnets, rather than steel springs, to move and engage Zipp's lightweight Metal Injection Moulded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn't a more secure freehub mechanism on the market.ImpressThis rear-wheel employs Zipp's ImPress graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do - help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability.Features: Rim Material: Carbon with UD Fibre finish with Impress technology Use: Road Axle Type: QR 135mm (quick release) Internal Rim Width: 18mm Rim Depth: 82mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC HexFin Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Hub: Cognition Axle Material: Aluminium Bearings: Cartridge - Stainless Steel Driver Mechanism: Axial Clutch Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheelTechnologies: New Zipp graphics and cosmetic identity that screams speed, applied using Zipp's ImPress direct-print technology. 19mm internal width and tubeless compatibility for optimisation of wider tyres with lower tyre pressure.
