CO CORSA RSA G+

£49.99 www.vittoria.com

Vittoria say the Corsa G+ is made significantly faster, grippier and more puncture resistant by its inclusion of graphene technology. There’s no questioning the grip and they feel especially gummy in the dry, giving really confident cornering when we raced them last summer. They’re wonderfully supple, too, and seem quick. At 35.2 watts, the lab test result looks relatively poor but owing to availability the test tyre was a 23. A 25 would have certainly been close to the Specialized and Continental. The Vittorias are the heaviest (238g) of this group – for a pair that’s 64g of rotating (therefore, more crucial) weight gain over the Michelins. Back-to-back, that’s enough to be tangible on a steep climb if you’re tuned in enough. There’s an even faster Corsa Speed G+ model but it’s fast wearing and punctureprone, so it’s literally race-day only. This Corsa G+ is much more usable.
