DT Swiss PR 1400 Dicut 21 Disc Tubeless Ready wheelset

PR 1400 Dicut 21 Disc - a high-end aluminium DT Swiss racing wheelset

If aluminum is your choice, you should take a very close look at the PR 1400 Dicut 21. Wide, asymmetric and lightweight rims make for an outstanding stiffness to weight ratio. The high-end, 240s-based hubs and the tubeless-compatible rims which feature sophisticated waterslide graphics, ensure an elegant appearance and make it easy for you to conquer yourself, your friends or your competitors on the next big ride in the mountains.

Technologies

Performance
#Leadtheride. Performance is the part of your energy that is brought to the road and that part is pretty big with DT Swiss Performance wheels. Just what you need when you are leading your buddies up epic mountain roads or when making the decisive move on the days last descent.

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!

Dicut
DT Swiss’s lightest, stiffest and most aerodynamic hub and spoke system, aimed squarely at competitive road and track riding where speed is the overwhelming priority, uses custom Nailhead spokes that can hold much higher tensions.
