FREQUENTLY ASKED QUESTIONS
Is the belt likely to derail ? Does it work in the mud ? What if a pebble gets stuck ?
Our prototypes have been equipped with Carbon Drive belts since 2010 and we have never had a particular problem with a chain. On the contrary, the service life is superior, it is lighter and requires no maintenance. In addition, the yield is better in difficult conditions (rain, mud, dust).

Is it heavier than a conventional transmission ?
No, we did a comparison here. It is necessary to take into account all the elements that replace the transmission to compare the masses.
How long is the gearbox guaranteed ? What is the life of the gearbox ?
We guarantee the gearbox 5 years. But that does not mean that it will not last longer, the gearbox will accompany you without problem during these 5 years and surely more!
By way of comparison, a derailleur transmission, when you drive regularly, requires changing chain + chain + cassette every 6 months/1 year. Not to mention the risk that a branch or a stone will tear out your derailleur.
About maintenance ?
The maintenance is simple: a drain after break-in (a few months) then 1 or 2 times a year depending on your use. The replacement of the control cables is done without removing the box.
And the after sales service ?
The parts or subassemblies to be replaced are available. The assembly and disassembly are simple and can be done by you or your retailer.
