When motor assistance and leg power meet, the range of terrain a bike can conquer grows almost exponentially. The H 1900 SPLINE is designed for this, now upgraded with the famous DT Swiss Ratchet technology. The Ratchet LN system distributes the combined forces from the rider and the motor over a larger area than the previous pawl freehub systems, increasing the systems' durability thanks to lower load peaks. The 370 hub enables full power transmission to the ground with reinforced hybrid spokes laced to a resistant aluminum rim, available in two inner widths.Features: - RIM: An aluminum, hooked, tubeless ready rim available in 30 or 35 mm of inner width and in 29´´ or 27.5´´.- FREEHUB BODY: The cassette interface of the freehub body is optimized with a specific hardened steel for the higher loads that occur on eMTBs.Specifications: - HUB TYPE: 370 with Ratchet LN 18- RIM: Aluminum, Hooked / Crotchet tubeless TC- INNER WIDTH: 30 mm, 35 mm- SPOKES: DT hybrid 1Technology: - Tubeless- Engagement Angle- Ratchet Ln- Bearing- Prolock
