技术

我们对于工程艺术深信不疑,并为了追求卓越的产品开发流程而努力。我们的理念是透过内部研发的技术来不断地突破极限。

The new DF technology is an anti-pedal kickback device simplified to the max. The DF technology releases the pedal kickback at the point where it occurs: in the freehub.

Ratchet EXP is the lightest freehub system from DT Swiss. The fusion of the ratchet and the threaded ring in the Ratchet EXP hub increases durability while decreasing weight.

What is the engagement angle, how does this angle affect riding performance and is the conventional wisdom "the more the better" really always better?
