SPIRIT
You will never cross the city again in the same way with a karcass! A karcass bike is a pure emotion, this is what you see, this is what they will see. Well-designed to create an aerodynamic bike with a singular mobility, our frame is made of a specific aluminum alloy. In addition, it has a flat-design machined structure which is unique around the world. The geometry gives a perfect power transmission for the city.
MULTI-SPEED versus FIXED GEAR
All our frames are sold as a multispeed bike (11 speeds) in a standard way. But you can switch as you want to a track bike configuration, without changing your frame. Just change the bottom bracket
(see spare part Bottom bracket BSA or Bottom bracket BB30)
BOTTOM BRACKET
All our frames are set up with BSA bottom bracket shell in a standard way. However, you can switch as you want to a BB30 bottom bracket to put up a larger range of cranksets.
(see spare part Bottom bracket BSA or Bottom bracket BB30).
DROPOUTS
The stainless steel machined track dropout inserts allow a wider range of horizontal adjustment for the rear wheel in case of track bike configuration. Moreover, they can also be changed in order to keep your bike clean.
(see spare part Dropout)
THE FORK
To complete this set, we have selected the Columbus Air Tusk Carbon fork, designed for time trial and triathlon, which uses an aerodynamic bladed profile made from variable-section carbon fibers to reduce resistance. But also for her design who match perfectly with our frame.
