Product:Mavic Cosmic Carbone 40 C
Price as reviewed:£0.00
There’s nothing quite like throwing yourself down a mountain to test a carbon clincher wheelset – and Mavic’s confidence in the 40 C’s stopping power certainly isn’t misplaced.
A combination of an early start and the previous night’s rain on the first steep descents swiftly confirmed this, albeit to the soundtrack of piercing braking squeals.
The inevitable gruelling ascent demonstrated stiffness and left me questioning the wheelset weight, although my lack of form was probably the greater penalty.
The pasting I received on the climbs left little energy to investigate further and the lack of gusting winds meant stability went unchecked - so watch this space for further testing back in blustery Britain. UK RRP coming soon.
