E-bike compliant Graphene compound rolls fast, and when used on an e-bike, extends battery life. Reflective sidewall stripe increases your visibility for oncoming motorists. The Solid Shielding puncture protection layer makes punctures a thing of a past. As with all Vittoria Tech Series tires, the mix of performance and durability add up to a great value!
