The design is use the same mould of FSA SLK cranksets with its integrated spider. This is carbon – or at least an aluminium core with a structural carbon outer finish.
The CNC’d rings offer shifting that’s in the middle for both speed and smoothness – but stiffness was disappointing. We actually ended up testing it several times to make sure of the figures. It is adequate, but at this price we’d expect more.
The quality and finish is all good, and the price and weight are also competitive, worth you to have it!
