The DF technology was developed by DT Swiss to specifically decouple the rear triangle of a mountain bike from the drivetrain. The aim is to reduce unwanted pedal kickback and give the suspension more freedom of movement. The result: a more sensitive response from the rear triangle, more traction and a noticeably smoother overall performance on demanding trails.

Technically, the system is still based on the tried-and-tested 90T pulleys with a fast pressure angle of four degrees, as known from the DEG ratchets. What is new, however, is the option to set the degree of freedom individually. Mountain bikers can choose between three options; 0, 10 or 20 degrees, and thus adapt the setup specifically to the terrain, riding style or bike geometry. The wheels are delivered with a zero-degree setting as standard, making it easy and low-maintenance to change them.

Reserve emphasizes that the integration of the DF hubs has no disadvantages: Neither weight nor price increase compared to previous wheels with DT Swiss 350-DEG hubs. At the same time, the manufacturer promises a significant increase in performance, especially on technically demanding routes. As usual, buyers also benefit from the lifetime warranty on Reserve rims.

The carbon models Reserve 30 HD and 30 SL are priced at 1799 euros each, while the downhill model 30 DH Carbon is priced at 1899 euros. The aluminum versions 30 HD and 30 SL are available for 699 euros each. The new aftermarket wheels with DT Swiss DF hubs should be available from the end of January.
