Kelly E.wrote a review of Vittoria Corsa Speed G Plus Tire - Tubeless on September 18, 2017
Familiarity: I've used it once or twice and have initial impressions
The tires are definitely fast, but the quality/ construction is horrible. The casing is made of rice paper which offers zero puncture resistance. I've managed to get 300 miles out of mine, but had to patch both tires after every ride. For me it's just not worth the hassle. Maybe these tires would be fine for race day only, but for that application I would choose tubulars first.
Anyhow, I cannot recommend these tires.
