No such thing as a free lunch, BUT, as a guy that rides tubies everyday, Conti Sprinter Gatorskins are great tires. Same extra threads in the casing as the clincher gatorskin, about $56 more than the sprinter. What you give up is a wee bit of suppleness found on a cotton tubie like the Vittoria. Still a better ride than any clincher(helmet-ON, flak vest-ON), but you give up a little 'comfort' for the man made casing of Conti vs cotton of Vittoria and others.
The only thing that costs you with tubies is the gluing on part which is no big deal and doesn't take days like some have said.
What you get is a great ride, safety, better cornering...and some 'bling' compared to the other nancys who still ride clinchers......(joking, take it easy!!)
