I’ve done four 70.3’s on Corsa Speed G2 with baby powdered latex tubes with zero flats.
I feel I’m taking an unnecessary risk when GP5k’s are just so fast and good (heck, I train on GP5k’s with a long of gravel tossed in!), so I’m debating switching for StG …
the nomenclature of the various tire models can be confusing. The really fast Vittoria is the corsa speed g2.0. The tire in the test is the Corsa G 2.0, which is has heavier tread, I believe. There is also a Corsa Control. Use the comparison tool on the website for confirmation.
Completely anecdotal but I wrecked a Corsa speed tire earlier this year when I locked up my rear wheel in heavy braking. It was only locked up for a couple of seconds but that was enough to burn a hole through it and it blew out.
Really fast tire but very fragile. “worth it” is in the eye of the beholder.
