DT Swiss HX 1501 Spline 30 Boost Rear WheelDesigned for riders who are looking for the ultimate performance. The rim is combined with a hub shell that offers better resistance to drive and braking torques that are common on modern E-MTBs. This resistance is made possible by reinforced spokes, so that even greater accelerations can be generated than with the previous DT Swiss hybrid product range. Each component has been carefully designed, produced and tested to ensure a stress-free ride as well as maximum fun, regardless of the rider's level. Suitable for both mountain bikes and electronic mountain bikes (E-MTBs), this is a perfect choice for tackling the demands of modern mountain riding.Aluminium MTB Rear Wheel with Tubeless Ready TechnologyTubeless tyres offer several distinct advantages over the traditional tyre and tube combination. The tyre can be run at lower pressures without risking "snakebites", thus providing more grip. The lower pressure also provides a more comfortable ride. The absence of the tube means that there is no friction between the tube and the tyre, and therefore less rolling resistance when riding off-road and over obstacles. This model is tubeless ready, so you can enjoy tubeless advantages such as the ability to run lower tyre pressures for increased stability, comfort and fewer chances of flats or punctures.DT Swiss Pro Lock TechnologyDT Pro Lock spoke nipples prevent the spoke-nipple connection from loosening on its own. A patented two-component adhesive is injected into the nipple thread, which allows the construction of an extremely durable rear wheel. As soon as the nipples are screwed in, the adhesive is activated and then hardens completely. Repeated re-centring is easily possible, although the adhesive strength decreases slightly with each re-centring.Ratchet EXP OSThe use of a single cylindrical spring results in less system wear while allowing faster full interlocking. With a full mesh of 30 teeth, the power generated by the engine and rider is transmitted evenly over a wide contact area, resulting in superior reliability. A larger double thread distributes loads over a wider area, reducing peak loads. This increases the service life of the system and even enables the transmission of greater torque. The axle was tested in FEM analyses to determine the bending load when riding an E-MTB and to optimise the axle resistance.Features: Material: Aluminium Use: Mountain Bike (MTB); Electric Mountain Bike (E-MTB) Axle Size: Rear: 12x148mm Boost Spokes: 28 DT Hybrid spokes Nipples: DT Pro Lock, Squorx Pro Head Hubs: DT Swiss 240 Freehub Type: SRAM XD Freehub System: Ratchet EXP OS 30 Size: 29" ETRTO: 30-622 ASTM Category: 4 Brake Type: Disc brake, 6-bolt Valve Hole Diameter: 6.5mm Rim Width: 35mm Inner Profile Width: 30mm Rim Profile Height: 25mm Single or Pair: Single, rear wheel Weight Limit: 140kgTechnologies: Optimised for use on E-MTBs.
