Lightweight Rim Prime has experimented with numerous types of resin and tested countless new lay ups before it settled on its new and improved Primavera 50 rim. But, that’s not all, the brand has upgraded to a higher grade of carbon, saving precious grams, and improving on the impact strength/weight ratio making the new Primavera 50 their best rim yet. Wider = Improved Performance The Prime Primavera 50 Carbon Wheelset features a 50mm deep aero rim profile to provide strong aerodynamic properties by reducing the amount of turbulence when the air meets the spokes. The Primavera 50 combines this with a wider rim profile to create a more linear contour between the tyre and rim interface, reducing rolling resistance and creating a greater contact patch for greater stability in corners. Greater Strength To Weight Ratio Built-up using an SR1, CNC machined 6061 alloy hub body and DT Swiss spokes, the Prime Primavera 50 Carbon Wheelset creates a stiffer wheel with a greater strength to weight ratio and more reactivity. Featuring an incorporated notch, the newly developed shape of the end caps simplifies disassembly significantly and therefore makes maintenance even easier. Its Star Ratchet hub also provides superior reliability, due to each of the ratchets engaging simultaneously every time. Prime has also ensured that tool free freehub conversion is possible.

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.

The new Shamal Ultra C17 represents the same fantastic performance that has made it THE go-to aluminium race wheel for the better part of two decades while adding even more versatility and performance. The new, wider profile means the C17 standard is perfect for use with the increasingly popular 25/28mm tyre sizes. USB Bearings are ceramic which vastly reduces the weight and greatly improves the smoothness of the bearings. The ceramic ball bearings inside also mean that maintenance will be far less common and it has a much higher resistance to corrosion than standard bearings. The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left-hand side. The new C17 also allows for a more sure-footed grip in addition to increased comfort while increasing rigidity and thus reactivity at the same time thanks to its wider stance and optimized material usage. Features: Toroidal Milling reduces the peripheral weight of the rim for great reactivity Dynamic Balance where every point of the rim is counterbalanced by an equal weight on the opposite side Ultra-Fit for easy tyre mounting and improved performance for clincher tyres MOMAG: the external rim profile is free of holes, so the structural integrity of the wheel is increased and there is no need for rim tape Differentiated rim height, 27mm front & 30mm rear for optimized structural integrity and performance Carbon hub with USB bearings, aluminium axle Aerodynamic aluminium spokes with exclusive Mega-G3 spoke pattern Weight: 1449g Tech Specs: Spokes Spoke Count: 16 Front and 21 (G3) Rear RDB - Rim Dynamic Balance Aerodynamic Double-Butted Aluminium spokes Ultraliner / DRSC Geometry Self-Locking Aluminium nipples Rims Profile Height: Differentiated (24/27mm at the front - 27/30mm at the rear Material: Aluminium Rim Section: (Height/width): differentiated/22mm Tyre fitment - Clincher with inner tubes Hubs Carbon and aluminium hub USB bearings Width: 100mm (Front) / 130mm (Rear) Oversize flange Cup-and-cone bearing system Freehub: CA 9/10/11/12x, SH 11x or 9/10x with spacers In The Box: New, re-designed quick-release skewers User Manual Warranty Booklet Campagnolo Wheel Identification Card

Building on what it learned with its Gen 2 Version, Stages has developed its technology even further for this latest model. Built on to a Shimano Dura-Ace R9100 crankset, it measures the power output of each of the rider's legs and the crankset is individually calibrated to ensure its accuracy. Stages produce power meters that both avid amateurs and professionals at the top of their game can trust. Reliable Readings In All Conditions To ensure consistency of measurement, Stages introduced a world-first feature to its power meters. This feature is called “Active temperature Compensation” and it is built in as standard to account for sudden temperature changes, which if not accounted for, would result in false and inaccurate data. Stable Connection Stages have made additional improvements to the Bluetooth and ANT+ transmitters and the accelerometer. This ensures a stable and powerful connection with your cycle computer is maintained and a faster sampling rate for more up-to-date feedback on your performance.
