New Wilier Zero SLR disc brake bike skims the UCI 6.8kg weight limit

Wilier has used its integration expertise to develop a stiff, low weight machine

Wilier says that the new Zero SLR weights just 6.8kg with 28mm clincher tyres, while the spec raced by Total Direct Energie, with tubular tyres, comes in at 6.5kg. That’s pretty impressive for a disc brake bike and just about on the UCI weight limit for racing.

Wilier has achieved that weight while also increasing the frame stiffness over its older Zero.7 and Zero.6, with a stiffness to weight increase of 24%. The claimed frame weight for a painted (matt black) size medium frame is 780g, paired with a 345g fork. Wilier has made use of a new high modulus carbon fibre with a liquid crystal polymer incorporated into the resin and a multidirectional fibre mesh, which it says also improves the damping qualities of the frame.
