While there may be a linear relationship between increased tire size and increased fun this relationship only holds true when wider tires are paired with the correct width rims. Having a 2.8' or high-volume tire mated to a narrow rim makes for a squirmy poor handling experience and when you’re on the hunt for additional fun these characteristics are undesirable. Lucky for you the new age of traction stability and speed has arrived—and its name is the Traverse 38 SL Fattie 27.5. Along with light overall weight stiffness and durability another top priority for the Traverse SL was ease of use. First off we got rid of the creaky straight-pull spokes and corrosion-prone alloy nipples. Next up we landed on 28 J-bend spokes for front and rear wheels that are all the same length—making it easy to find replacements if needed. And finally we engineered a new hub design with a wider profile and higher flange to aid in overall stiffness. While our 38-millimeter Traverse SL is already wider than most offerings the benefits of three-inch tires become more apparent with a proper rim interface. In search for the proper width our engineers tested various iterations from 30 to 45 millimetres to determine where the sweet spot lies. What they ended up with is a 38-millimeter internal rim width that turns the Traverse 38 SL Fatties into descending machines . A wide internal rim width endows riders with a variety of advantages that are exemplified even more with plus-sized tires. The extra width allows for more tire volume translating into more supple ride qualities and better support for the tire meaning that you'll experience less 'burping' when riding tubeless and a drastic increase in traction. After determining the proper rim width for the plus-sized application we began designing the rim using the same low-weight high-strength technologies used in the Traverse SL and the Control SL. With this we started with our Zero Bead Hook design that effectively eliminates the biggest weak spot found in traditional rims and topped it off by using high-modulus carbon fibre to keep the weight down. And to further this theme the wheels also include the Roval tubeless plug system which sheds an additional 50 grams-per-wheel compared to a rim strip Each Traverse 38 SL Fattie is hand-built to our own alloy hubs with DT Swiss Competition Race spokes. Inside our hubs you'll find sealed cartridge bearings all-around and a quick-engaging 54t DT Swiss star ratchet system in the rear that allows you to power over rocks and roots without delay. And while machines do a decent job of building wheels we choose professionally trained humans to build ours as they catch various flaws that a machine would otherwise miss.

Key Features: Designed to add serious all-conditions aerodynamic advantage in a durable Hybrid-certified package; the HEC 1400's are a superb upgrade for those looking to squeeze every ounce of performance from a high-end E-road bike, The carbon HEC rims were designed from scratch in conjunction with former F1 head of engineering JP Ballard and his team at the GST wind tunnel in Immenstaad, Germany, Using a bespoke fluid dynamic analysis system that for the first time allowed the designers to model and quantify the effect of crosswinds on a wheel's handling a rim profile was developed that gives an optimal balance between aerodynamics and handling, This is why the HEC rim is precisely 47 mm deep and 27 mm wide, any wider and you'd see an unacceptable increase in drag, any deeper and you'd compromise handling in rough conditions, we call this concept Aero+ and the result is a blindingly fast yet truly all conditions E-Road wheel, Reinforced Hybrid optimised SPLINE hub-shells, a strengthened 24-tooth ratchet and steel freehub bodies ensure long term durability even under prolonged hi-torque use, Thicker spokes greatly extend fatigue life and transfer the added torque from the hub more efficiently, 19 mm internal rim profile is optimised for 25-28 c tyres, For those looking to use the latest tyre tech the HEC 1400's come tubeless ready but can also be used with standard clinchers, Available in either standard 100/142 x 12 or 110/148 x 12 'Road BOOST' to fit the latest E-road designs, the Non-Boost versions can be adapted for Q/R using end caps (not included), Maximum recommended system weight: 130 KG, When bought as a pair they will include both Shimano and SRAM XDR steel freehubs, 6-bolt rotor adaptors, tubeless rim tape and valves, Weight: Front 711 grams Rear: 838 grams.
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.
