Dt-swiss GR 1600 Spline® DB 25 Gravel Front Wheel 27.5″/650B

Enjoy the fun of cycling off the road, with an endless desire to discover!
The GR 1600 Spline® DB 25 front wheel was developed for all those gravel adventures that can only be experienced far away from the asphalt and the ambitious race cycling community. Are you already planning your next bikepacking trip?

The robust 27.5″ system wheel is equipped with reliable components for countless kilometres of riding fun. The wide, yet lightweight, aluminium rim is connected to the high-quality DT Swiss 350 Spline® hub via sturdy straightpull spokes, for a stiff and resilient wheel. With its excellent bearings, the rotation centre promises high durability. The wheel stand out for reliable control and safe handling when manoeuvring over challenging gravel trails. Even when loaded down with luggage.

The reliable GR 1600 system wheel is ideal for use with contemporary large-volume gravel tyres. If there is enough space at the fork, then especially thick, off-road tyres can be mounted on the wide aluminium rim, to add more volume to the rims. Tyre widths far beyond the usual 35-40 mm can be mounted, with which you benefit from more traction, grip and comfort. Especially on bumpy gravel tracks and winding forest trails, the agile 27.5 inch wheel can really show off its strengths. 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.

Whether on a quick after-work ride, a weekend excursion or a weeks long bikepacking tour: The GR 1600 Spline® gives you the freedom to experience the world on two wheels again and again.

Technologies:

• 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.
