★★★★★
As 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.
Tarik

★★★★★
Reliability 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.
