Quadrofenia is our designer's favourite sprocket and was designed to be light but strong.
It proved its class during long tests on street and park.
The best available aluminium alloy 7075 T6 from our european factories made it even more schock-resist.
As all Mantra's sprockets, Quadrofenias are special CNC machined and then hand finished in our hidden laboratory in order
to add 100% of custom work.
