DT Swiss XR 1700 Spline 25 Boost 6 fori 29 wheelset
Aluminium wheel with breathtaking acceleration developed to meet all cross-country requirements.
If for you cross-country means high speed after work and occasional endurance racing, then you should take a closer look at the XR 1700 SPLINE. Lightweight, welded aluminium cross-country rims, reliable RATCHET SL 36T hubs and Swiss precision finishing, from racing spokes to the characteristic build quality of DT Swiss wheels. A wheel set for everyday challenges, with yourself, with your friends or in competition.
Rim
Thanks to the welded joint, the 25 mm wide aluminium rim is not only light but also extremely robust.
Hub
The redesigned 350 hub is now equipped with a Ratchet SL 36 system.
Nipples
DT Pro Lock Squorx nipples contribute to longevity.
Bushing
The notch on the bushing simplifies disassembly.

Technologies
Tubeless
All DT Swiss wheels are compatible with tubeless technology and the ASM versions are tubeless-ready, equipped with tubeless tape and valves. Tubeless tyres have several advantages over the traditional combination of tube and clincher: the tyre can be inflated to a lower pressure level, without the risk of pinching (so-called "snakebite" punctures) and providing superior grip. The lower pressure offers greater comfort in the saddle and the absence of a chamber eliminates friction between the chamber and the tyre, resulting in less rolling resistance on terrain and obstacles. The use of a tubeless sealing fluid enables the tyre to self-seal punctures and small cuts. A great advantage for all those who like to ride for a long time and who, in the event of a problem, would find themselves several kilometres away from the nearest repair shop.
Bearings
DT Swiss hubs are designed to function optimally once fitted to the bike. To this end, the tightening torque generated by the wheel mounting system must be taken into account when manufacturing the hubs. Find out how to ensure the optimal rotational capacity of ball bearings and why DT Swiss does not produce hubs with adjustable bearing clearance. In order for a bearing to be able to rotate, a certain play, in the order of a micrometre, is required. Without this clearance, the bearing cannot rotate. Bearing clearance is both radial and axial. The axial clearance is the possible longitudinal displacement of one bearing ring relative to the other in the absence of load, while the radial clearance is measured vertically with respect to the central axis of the bearing.
Engagement angle
The engagement angle (or engagement angle) corresponds to the maximum amplitude of rotation that the freewheel body can make before the teeth of the system engage into each other imparting acceleration to the hub. This angle is calculated by dividing 360º by the number of engagement points of the freewheel system.
DT Pro Lock
In the DT Pro Lock process, a two-component adhesive liquid is injected into the thread of the nipple, enabling extremely reliable wheel assembly. By tightening the nipple on the spoke, the two-component adhesive starts to act and harden. Once fully hardened, it is still possible to centre the wheel several times, with only a slight decrease in the threadlocking effect.
Ratchet
Equipped with high-precision toothed sprockets, the patented freewheel system guarantees superior levels of performance and reliability. The teeth of the sprockets engage simultaneously in each other and the loads are distributed equally over a large contact surface. The plug-in construction of the Ratchet system hubs guarantees fast and tool-free maintenance. The no-tool concept allows switching to a different transmission standard in seconds.
PHR System - Pro Head Reinforcement
The PHR reinforcement system increases the load-bearing surface of the nipples on the rim and reduces localised stresses. Due to the limited load peaks, an even lighter rim can be constructed. In addition, the shape of the washer acts as a ball joint and automatically aligns the DT Squorx Pro Head® ball nipples with the spoke, reducing the risk of broken spokes or rim cracks.
