GR 1600 SPLINE® db 25 Gravel Rear Wheel 28"/700C (12x142mm) Ratchet SL SRAM XDR™

Be ready for UNPAVED ADVENTURES!
With the launch of their gravel-dedicated system wheels, the wheel specialists of the traditional manufacturer DT Swiss discover a new territory that used to be reserved for mountain bikers in the past but today fascinates adventurous road cyclists.

With the GR 1600 SPLINE® 25 rear wheel, you are geared up for your next bikepacking tour and all gravel adventures or experiences you can make far away from paved roads.
The robust aluminium rim impresses with a low weight, high stiffness and outstanding durability. An inner rim width of 24mm additionally provides a large tyre volume, which takes comfort on demanding gravel roads to a new level.
Optimised for use with powerful disc brakes, the high-quality welded rim rotates around the reliable DT350 rear hub, which ensures efficient running and outstanding power transfer with its excellent bearings and the proven weight-reduced 36T ratchet freewheel system.

Aerodynamic DT Swiss aero comp® straight pull and DT Swiss new aero® straight pull bladed spokes give the entire wheel system a perfect balance of comfort and stiffness. Every DT Swiss wheel is handmade. The concept of manual production is not only a guarantee for a stable and durable wheel. Know-how and, above all, experience are required to produce a high-quality wheelset.

For maximum off-road performance, the DT Swiss GR 1600 SPLINE® 25 wheel also offers excellent tubeless compatibility. When used without tubes, you’ll benefit from less weight, improved puncture resistance, reduced rolling resistance and increased comfort, since you can ride with lower air pressure on unpaved roads.
So, are you ready to explore the world? The GR 1600 SPLINE® db 25 rear wheel from DT Swiss is!

Technologies:

RATCHET SL:
With the Ratchet SL freewheel system from DT Swiss, the designation ”SL” (Super Light) means that the ratchets are lighter than those of the classic DT Ratchet System, thanks to additional machining. Depending on the equipment, the ratchets of the Ratchet System hubs have an engagement angle between 6.7° and 20°. The system stands out for high reliability thanks to the simultaneous meshing of the teeth, which leads to significantly lower point loads. The no-tool concept allows easy maintenance and tool-free conversion to common axle and freehub body standards.

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.
