The primary advantages of the Whisper Tech include:
Drastic Noise Reduction: The hub operates significantly quieter than standard hubs, reducing engagement noise (energy) by about 90%.
Ultra-Low Freewheeling Resistance: It offers over 65% reduction of drag.
Innovative Energy Absorption: Unlike traditional pawl-and-ratchet systems that release impact energy as noise, the Whisper Tech system uses pawls designed to absorb engagement energy.
Enhanced Reliability: The hub achieves long-term durability by structurally managing pawl impact rather than relying solely on grease damping, which often increases drag.

★★★★★TarikAs a bike courier, I don’t want to ride
anything else anymore. I’d say I’m usually a bit negligent with maintenance. However,
be it snow, mud, sand, salt—it’s still a smooth ride! In addition, it’s one of
the most beautiful chainrings on the market! I bought a new one a year ago, but
the old one still hasn’t worn out.Germany
★★★★★Sina TemmenReliability I can always count on – Thank you, Kappstein!
For over five years, I’ve been riding on the track with chainrings and sprockets from Kappstein – and in all that time, there hasn’t been a single moment where I doubted my equipment. Especially on the track, where precision and reliability are crucial, that’s invaluable to me.
