The SL4DB wheels are lighter and better performing than the previous version thanks to the RS hubs upgrade. This wheelset has been designed with speed at its heart, but is versatile enough to tackle any kind of course.The 45mm deep rim features an asymmetric design, combined with a 26 mm wide cross section that guarantees lightness and stability. The 24 spokes count provides high stiffness at a very low weight. The wider rim generation provides better support to the tyre and reduces the rolling resistance, and increases wheel strength. These wheels are tubeless ready straight out of the box, but are also suitable for clincher tyres. The RS hubs considerably improve the wheel's smoothness and guarantee better pedal force transmission. The special RS hubs have been completely reengineered from the previous SL generation. At only 307g for the pair, they offer an 80g saving compared to the SL version. They are also 20% smaller than the previous generation with flanges designed to reduce drag on both the front and rear hub. The hubs are also machined with a rifling design which improves aerodynamics and amplifies the downforce effect of airflow against the hub, giving more stability at higher speeds. **Technical Specification:*** Material: High Modulus Carbon, UD and 3K combined structure with differentiated thickness* Rim Height: 45mm* Rim Width: 19mm (Internal) / 26mm (External)* Spokes: Black, 24 front and rear* Nipples: Internal Alloy, 15mm length, Self Locking ABS* Hub: AL7075 Hub body with 20T ratchet, 17mm front axle and 15mm rear axle* Bearings: Steel* Disc Brake Type: Shimano Centre Lock* Thru Axle Compatibility: 12x100mm (front) / 12x142mm (rear)* Freehub: Available with Campagnolo, Campagnolo N3W, Shimano or Sram XD-R compatible versions* Type Compatibility: Suitable for Tubeless or Clincher tyres.
