The system
that makes Driven a unique product was developed by Ceramicspeed in
collaboration with the Department of Mechanical Engineering of the University
of Colorado. In the absence of the chain, the drive is via a super-light shaft
equipped at each end with a series of ceramic bearings. The shaft is mounted on
the front toothed wheel and, at the rear, on a system of thirteen gears
(leading to thirteen different speeds) arranged on a flat surface, which
replace the classic sprockets of traditional bikes. Tests carried out by the
company have shown a reduction in friction of 49% compared to the best chain
and derailleur system currently on the market and an overall efficiency
practically doubled. The only “defect” – if we can talk about a defect – is the
price. The cheapest chainless bicycle model currently available in the
Ceramicspeed catalogue is on sale at a price of just under $2000: saying
goodbye to the old chain is still a luxury for a few!
