DT Swiss M 1900 SPLINE® 30 MTB Rear Wheel 29“ BOOST (12x148mm) SHIMANO MICRO SPLINE

The all-rounder among the DT Swiss system wheels – top technology from the Swiss wheel specialists in an affordable overall package!

The M 1900 SPLINE® rear wheel with 30 mm inner width was specially developed for the requirements of modern all-mountain bikes. The high-quality, CNC-machined 370 SPLINE ® hub with the Ratchet LN freehub system incorporates the entire hub know-how of DT Swiss.

Forces from and to the hub are transmitted via particularly robust straight-pull spokes. The rims, which are as light as they are stable, impress with excellent support of the modern MTB tyre flanks and problem-free tubeless compatibility.


Technologies:

• RATCHET LN:
The Ratchet LN freehub system is the entry into the world of high-quality ratchet systems from DT Swiss and raises the items from the lower price segment to a new level. In the reliable 370 hub, the Ratchet LN freehub replaces the classic 3-pawl freehub system. It uses the same internal parts as the ratchet system. The difference between the two systems is that the freehub system is sealed via a sealing ring on the freehub body. This means that older ratchet systems with Ratchet LN can also be converted to a DT Swiss Ratchet system.

• TUBELESS:
All DT Swiss wheels are tubeless ready. The profiles of the DT Swiss rims are specially designed for tubeless use. The rim profile makes it easier to fit the right tyre and ensures a perfect fit. The tubeless system of the rim consists of DT Swiss tubeless ready tape for sealing and a DT Swiss tubeless valve in a length that complies with the rim. When using tubeless ready tyres, a compatible sealant must be used. However, it is also possible to use a conventional combination of tyre and inner tube.

• BEARINGS:
Having learned from years of experience, DT Swiss only uses durable cartridge bearings without bearing play adjustment. DT Swiss hubs are designed to have the optimum axial and radial bearing play when they are properly installed. The correct preload of the bearings to compensate for the clamping force of the wheel mounting system is the basis for a play-free hub with minimum friction.

• PRO LOCK®:
DT Pro Lock® prevents the spoke-nipple connection from loosening. In the Pro Lock® process, a special dual component adhesive is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and then hardens completely within a few hours. Re-truing the wheel is possible, yet it will cause a slight decrease in the adhesive power each time.
