60-11 for ganna.
can someone with tt knowlege tell me why ganna's running gp4000 clinchers for the giro tt? does this mean they're faster than gp5000s / tubs, or are these some other tyre?
@umop3pisdn @gbj_tester ?
Gp5ks are dogshit
GP4k clinchers have always tested well aerodynamically, they might have found that outweighs any Crr penalty.
