Technologies

Tubeless
Tubeless ready DT Swiss rims have further advantages over conventional rims. The design of their cross section allows for the tyre to easily pop in place when inflated, and more often than not a standard floor pump is all that‘s needed. Also the elaborate profile of DT Swiss rims ensures a precise and safe fit of the tyre even when ridden hard.

Ratchet system
The patented freewheel system, which features high-precision star ratchets, guarantees top performance and reliability. The no-tool concept allows extremely simple and quick maintenance.

The engagement angle is the degree to which a hub spins freely before transferring the riders power to the wheel. The smaller the angle, the faster the leg power reaches the ground, so a smaller engagement angle is generally better. It is important to know though, that there are limits on the minimally possible angle, as the reliability of the freewheel system partially depends on the angle too. What makes the Ratchet System hubs truly unique, is the fact that all teeth of the two ratchets engage simultaneously every time. Pawl hubs in comparison engage only a couple pawls simultaneously. Furthermore, in the case of pawl hubs, the contact surface is rather small, whereas in the case of the Ratchet System, the whole front face engages, creating much smaller point loads. The result is the legendary reliability of the Ratchet System hubs and distinctive sound as the star ratchets rotate against each other!

Prolock
Pro Lock® is a process where a patented, dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Retruing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.

Engagement Angle
A hotly discussed topic in the market right now - engagement angle! What is the engagement angle, how does this angle affect riding performance and is the conventional wisdom "the more the better" really always better?
The engagement angle is the maximum degree that the freehub body can rotate until the teeth of the freewheel system engage and accelerate the hub. This angle is calculated by dividing 360º by the number of engagement points of the freewheel system.
DT Swiss still believe that a system with 36 points of engagement represents the best optimization within this three dimensional perspective in terms of reliability, weight and points of engagement.

PHR – Pro Head Reinforcement system
The PHR system increases the load-bearing surface of the nipples on the rim and reduces localized stresses. Peak loads are reduced allowing to built the rim even lighter. The washer's shape also acts as a ball joint and automatically aligns the specific DT Squorx Pro Head® ball head nipples with the spoke further, reducing the risk of spoke failure or rim cracking.

Spline
DT Swiss’s classic straight pull system, a great balance between stiffness, comfort, low weight and easy serviceability, ideal for everyday road or mixed terrain use and uses readily available standard straight-pull spokes.
