The DT Swiss Hybrid MTB H 1900 Spline 29′ 35 mm Disc Center Lock Front Axle 15×110 mm – Front 12×148 mm BOOST is made of aluminium, now with Ratchet LN technology for extended eMTB rides. When motor assistance and human leg power are added together, the variety of terrain a bicycle can conquer is almost infinite. This is where the H 1900 Spline comes in, now enhanced with DT Swiss’ famous Ratchet technology. The Ratchet LN system distributes the combined forces of rider and motor over a larger surface area than previous ratchet cassette systems and increases the durability of the systems due to lower peak loads. The 370 hub allows full power transmission to the ground, with reinforced hybrid spokes and a strong aluminium rim offered in two inner widths.

Technologies:
– Spline: DT Swiss Spline wheels are built to meet the demands of modern cyclists, featuring the most advanced hub technology, smart spoke geometry and a lightweight freewheel system.
– Tubeless Ready: All DT Swiss wheels are compatible with tubeless tyres. The ASM versions are also ‘tubeless ready’, because they are already equipped with the tape and tubeless valves.
– Angle of engagement: The engagement angle is the maximum degree to which the cassette structure can rotate until the teeth of the freewheel system fully engage with each other and accelerate the hub. It is possible to calculate this angle by dividing the number of points of engagement of the freewheel system by 360º.
– Prolock: is a process by which a patented dual-compound liquid adhesive is injected into the nipple thread, promoting extremely durable wheel constructions. By screwing the head onto the spoke, the adhesive is activated and the adhesive starts to harden.
– Ratchet LN: allows you to convert DT Swiss hubs to the coveted Ratchet System. It only takes a few simple steps to incorporate the advantages of the Ratchet System, such as outstanding reliability and adaptability of the coupling angle, into existing DT Swiss ratchet system hubs.
