In this post, we look at the fruits of a very happy collaboration with Kappstein GmbH & Co.
Kappstein is a German manufacturer of precision components for bicycles. With their latest development, the Doppio system, they’ve achieved the not inconsiderable feat of fitting a 2-speed gearbox into a bottom bracket. The first gear (which is direct) gives way to a second “overdrive” gear, whereby a planetary gear unit with six micro cogs alters the pedaling ratio.
The guys at Kappstein asked us to build a stylish urban bike for them as a means to present this new product to the press, and this is the result:
The Doppio system has a widely spaced gearing ratio, offering a low first gear for strong acceleration out of intersections, and a high second gear capable of reaching dizzying speeds. So we set to work accordingly, and designed a sporty bike which would be up to the challenge.
Our new Nua CF carbon fork seemed like the perfect choice to go with our Nua Ti-CORE titanium frame, which continues to demonstrate its extreme versatility with each new set-up we use it for.
Super-strong Shimano hydraulic disc brakes were indispensable for stopping a rocket like this.
The Crank Brothers Cobalt wheels are robust, but with a sporty look which complements the rest of the bike.
Thomson make superb quality stems and seatposts which have become standard for the best custom builds.
A saddle and grips by Ergon complete this sporty yet eminently elegant and functional machine.
The entire transmission system is picked out in fiery red, from the minimalist shifter on the handlebar, to the Doppio itself (which we painted for the occasion), the Gates carbon belt drive, and even the gear cable.
To sum up: a bike which is lightweight, sporty, and extremely fun, yet maintains the elegance and functionality which characterise all our set-ups. A perfect mix of heart and head, passion and rationality.
