DT Swiss H1900 Spline 30 6 Bolt Boost eMTB 27.5 Wheel

A reliable aluminum wheelset now with Ratchet LN Technology for extended eMTB tours.

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.

Technologies

Tubeless -All DT Swiss wheelsets are tubeless compatible and the ASM versions come tubeless ready, equipped with tubeless tape and valves.

Engagement Angle -A hotly discussed topic in the market right now - engagement angle! What is the engagement angle, how does this angle affect riding performance and is the conventional wisdom "the more the better" really always better?

Ratchet LN

Bearing -DT Swiss hubs are designed to function optimally once installed in a bicycle. To achieve this, the clamping force created by the wheel mounting system must be taken into account when constructing a hub. Learn how to ensure the optimal rotating property of the ball bearings and discover why DT Swiss does not offer hubs with adjustable bearing clearance.

ProLock -Pro Lock is a process where a dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Re-truing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.

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.

Ratchet LN -First wheel equipped with the Ratchet LN system, for force distribution over a larger area, increasing durability.

Brake Interface -The brake interface is available in center lock or IS (6 bolt).

Spokes -DT Hybrid 1 spokes are reinforced and increase the lateral and torsional stiffness of the wheel.
