DT Swiss H 1900 Spline® 25 Hybrid SHIMANO MICRO SPLINE Disc BOOST 29" E-MTB Rear Wheel

"Get your flow!" – with the H 1900 Spline® 25 hybrid rear wheel from DT Swiss, made for your e-mountain bike!

DT Swiss is using the hashtag #missionhybrid to share their mission to meet all the requirements that e-MTB riders place on their components. High torques and a significantly higher system weight put much more strain on your wheels on demanding up- or downhill tracks than traditional, non-assist mountain bikes. Thanks to many years of experience in wheel building and modern test and analysis methods, DT Swiss has developed special hybrid components that are much more durable and robust than traditional MTB components – without suffering from overweight.

The rear H 1900 Spline® 25 system wheel is the perfect entry into the world of hybrid wheels by DT Swiss. It even feels at home on rougher terrain and is always up for new adventures thanks to a reliable Swiss precision hub, strong spokes and a robust, lightweight rim.
An inner rim width of 25 mm makes for lots of tyre volume, which helps you find the best grip – whether on loose gravel or on a rooty traverse, up- or downhill!

Tip:
Mountain bikers riding without electrical assistance can also benefit from the additional stability and durability these wheels offer, especially if they place high demands on the material.

Technologies:

• HYBRID HUB:
All DT Swiss HYBRID hubs have oversized housings with increased wall thickness, are equipped with heavy duty axles and have extra reinforced spoke mounts as well as oversized bearings and steel freewheel bodies. In addition, the rear hub models with ratchet freewheel system (350, 240) are equipped with reinforced 24-tooth ratchets made of hardened steel. Thanks to these optimisations, a system weight of up to 150 kg is permitted, despite only a slight increase in weight compared to a standard DT MTB hub. The result is a hub that can handle very high torques, offers direct propulsion and, combined with the other HYBRID components, produces extremely robust wheels.

• HYBRID-SPOKES:
The DT Swiss HYBRID system requires spokes that not only withstand the higher weight and torque of a modern E-MTB, but also fit perfectly with the oversized spoke mounts of the in-house HYBRID hubs. The specially-designed spokes feature reinforced and oversized straight-pull spoke heads which, together with the DT Pro Lock Squorx nipples, ensure that the combined power of rider and motor is also converted into propulsion.

• HYBRID RIM:
Lots of uphill and downhill rides on rough terrain with an E-MTB means that the rims have a very hard life. DT Swiss HYBRID rims have proven rim profiles with load-optimised cross-sections and are approved for a system weight of up to 150 kg. For maximum stability, the strength and material thickness have been increased wherever it makes sense. DT Swiss hybrid rims are reinforced to withstand up to 20% higher spoke pull out forces compared to DT Enduro rims.

• 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.
