DT Swiss E 1900 Spline 29' Boost 6 bolts front wheel

Get all the focus you need for your Enduro debut moment with this wheel

Your entire focus lies on the right line choice, the exact braking point and the spot-on steering movement. All the everyday stress fades away, you feel free and only hear the precise sound of the freehub system. The E 1900 Spline was developed precisely for these freewheeling moments. A proven aluminum rim, a Ratchet LN freehub system and hand-laced steel spokes provide the reliability required from an Enduro wheel. Start your EWS career.

Rim
Tubeless-capable, sleeved aluminum rims, featuring a specific 30mm internal width to hold the chosen line.

Hub
The E 1900 SPLINE 370 hub is now upgraded to the Ratchet LN freehub system for even higher reliability.

Ratchet LN
The reliability of the Ratchet System comes from the fact that each tooth engages simultaneously. In comparison, the pawl system has much smaller engagement surfaces.

Spokes
The 2.0 mm diameter DT champion spoke is made of steel to resist the high radial forces that occur on the wheel from the drive and brake torques.

Brake interface
The E 1900 SPLINE is available as 6-bolt option or as Centerlock.

Technologies

Tubeless technology
All DT Swiss wheelsets are tubeless compatible and the ASM versions come tubeless ready, equipped with tubeless tape and valves. Tubeless tires have a number of advantages over the conventional combination of tube and tire: without risking snakebites, the tire can be run with lower pressures providing better grip. The lower pressure also results in a more comfortable ride. Eliminating the tube means there is no friction between tube and tire and therefore less rolling resistance when the tire rolls over the ground and obstacles. If tubeless sealant is used, the tire can self-seal stings and small cuts. A big advantage for all those who like to ride long and far from the next bikeshop.

Bearing technology
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.

DT Pro Lock® technology
DT 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.

Ratchet LN Technology
Simultaneous engagement of the ratchets over a wide contact area distributes loads evenly for outstanding reliability. The modularity of the hub allows easy adjustment of the engagement angle as well as its freehub body. Ratchet LN allows DT Swiss hubs with pawl systems to be upgraded to Ratchet Systems. In order to make the conversion from pawl freehub system to the Ratchet LN system possible, the freehub system seal is placed on the freehub body and not on the hub shell like on the other Ratchet Systems.

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? The engagement angle is the maximum degree that the freehub body can rotate until the teeth of the freehub system engage and accelerate the hub. This angle is calculated by dividing 360º by the number of engagement points of the freehub system.
