Veloflex Criterium / Carbon Tubular Tire
See the official Veloflex web site for the full range of tires.
The Criterium has a 320 TPI casing compared to a 350 TPI casing for the Sprinter, so in theory it should ride a little more stiffly but be be slightly more puncture resistant. Not that a 320 TPI casing is non-supple.
The Criterium has a gum-colored sidewall, but the Carbon is the same tire with a black sidewall, so take your pick.
Good choice for the rear wheel
The Sprinter is my default tire of choice for the rear wheel, offering substantial extra tire life over the Record, provided one avoids punctures. The Criterium could also fill that role with somewhat longer service life.
I weighed brand new Criterium tires on my lab scale at the following weights:
Recommended pressure is around 115 PSI for my ~175 pound riding weight.
