Explore new paths with maximum speed!
The GRC 1400 Spline® DB 42 rear wheel will help you climb into the top class of speedy gravel biking. Just right for the Gravel speed-junkie in you!

The aerodynamic shape of the half-height carbon rims doesn’t just have a favourable effect on air resistance. While off road, the speedy high-end system wheel masters the challenges of unpaved forest and meadow trails with outstanding stiffness and first-class grip qualities for controllable speed: Whether you're racing or on your weekly gravel tour with your colleagues. In the midst of swirling clouds of dust on the gravel road the "gnashing of teeth" will take on a whole new meaning.

DT Swiss's benchmark Gravel carbon wheels are packed with a range of cutting-edge technologies,
starting with the proven smooth-running 240 Spline® hub. This has proven to be particularly reliable with its excellent bearing and keeps the tubeless ready carbon rim securely in place on the reinforced straightpull aero spokes. The weight-reduced Ratchet SL freewheel system, with its high-precision toothed pulleys, ensures fantastic propulsion. The 10° engagement angle ensures that your pedal stroke is converted directly into acceleration through direct engagement. Thanks to its tubeless compatibility, you can also enjoy the many advantages of modern tubeless systems. Lower weight, less rolling resistance, better puncture protection and higher comfort will turn each of your adventures into a real pleasure.

With the GRC 1400 Spline® System wheel, you'll have plenty of fun on the bike and enjoy every one of your adventures. It's time for new off-road adventures...


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, it is mandatory to use a compatible sealant. However, it is also possible to use a conventional combination of tyre and inner tube.

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.

Thanks to 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.

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.
