The high-quality wide strapping is specially designed for all-mountain/enduro practice. With excellent weight/rigidity ratio and low profile and wide profile for excellent traction and lateral rigidity. Perfect for 27.5+ mount with tyres in sections ranging from 2.25 to 2.8... Superb finish and tested and approved by Cécile Ravanel (World Championship EWS 2018). It offers a low and wide profile for lateral rigidity and better resistance to twisting. Discipline: Trail / All-Mountain / Enduro / E-Bike Diameter: 29 inches // Number of Spokes: 32 // Brake: Disc // Valve: Presta // Tyre Type: Tubeless Ready // Weight: 618 g - Material: Aluminium Dynamic with MGR Extrusion (Micro Gain Refining) - Shootpeen Finish, Laser Logos - Height: 19 mm / Internal Width: 30.5 mm / External Width: 35 mm in - ERD: 598 mm // ETRTO : 622 x 30.5 Spank rims have all Spank Industries know-how. 100% designed and manufactured in 2 factories of the brand with 5 unique patents and a house aluminium alloy. Engineered in dynamic aluminium, a home-made aluminium alloy with added silicon and magnesium offering mechanical properties comparable to carbon while displaying greater resistance over time, affordable price and being more responsible to the environment, MGR exclusive extrusion and forging which decreases the aluminium grain, improves the rigidity of the whole while reducing the weight. This rim has the OohBah profile at the same time. Thinner and Wider. Combining a concave outer wall with a convex inner tube, this profile offers better traction with more vivid accelerations, freer braking, more precise trajectory and improved overall comfort. The wave shape also reinforces the vertical rim walls for optimum reliability. BeadNip double hook technology improves the deep fit of the tyre rod in the rim, while the BeadBite concept (with CNC-machined 6 grooves) ensures an exceptional hold of the tyre while ensuring a perfect seal of the rim in Tubeless mount. So you can ride at low pressure without worrying about rattling or puncturing! Patented Vibrocore foam anti-vibration and resonance phenomenon, also improving structural rigidity of the rim. A must have! !
