Where should I start? These new S-Works Turbo 2BR T2/T5 tires, compared to the similar highly rated Vittoria Corsa N.EXT's, they roll faster, offer much better road feel, but much better puncture protection, and lighter weight, also better looks w/ tan wall. Wet cornering grip is on par too. I've ridden a set of these Turbo 2BR T2/T5 for more than 2000 miles now, suffered a few cuts to the tread of the tires, but so far not a single puncture. They're surprisingly easy to install and seat on rims, unlike the infamous GP5k S TR's. They may not be the fastest rolling tires on the market, but they are definitely the best all around tires for training and general everyday riding!
