Sprint to victory.
Whether you're competing against the clock or taking hard chicanes on the crit course, Veloflex's Sprinter Tubular Tire is there to help you hold your line like a train rides rails.
Veloflex's Sprinter is modeled after its predecessor the Servizio Corse. With continual development and refinement, the Sprinter tire hasn't only inherited this legacy, but it's creating its own. Italians know cycling, and to this end, Veloflex's tubulars are hand-sewn in Italy. The casing is Compressed Pes/Co corespun. This is layered on a Calicot puncture-resistant belt. "Calicot" is the French translation of the English word "calico." Basically, this refers to a style of weaving that's popular in India, whereby a layer of warp threads are woven one-under and one-over with a layer of weft. This gives the weave both strength and durability. The Calicot layer relies upon the tightness of the weave in order to achieve puncture-resistance.
To ensure both flexibility and an effective stiffness-to-weight ratio, the Sprinter's 350TPI, corespun casing comes into play. Essentially, this means that the casing fibers are made by twisting staple cotton fibers around a central filament core, creating one yarn from multiple fibers. As a result, the material is between 40 and 50% stronger than typically spun materials, while retaining a similar, if not lower, overall weight. Additionally, the 350TPI cotton casing provides the ideal stiffness-to-weight ratio. By this, we mean that the tire's weight hovers around 225 grams, while still retaining a perfect level of flexibility for cornering. And for reference, most top-tier race tubulars top-out at around 320TPI.
Veloflex uses as many naturally sourced materials as possible, and the Sprinter is no exception. The high-density casing was coated in natural rubber, creating a supple and responsive tire that absorbs energy and rebounds from irregularities in the road surface — again minimizing resistance. It features a slight pebble pattern to help you stick to the tarmac while you rail corners.
The Veloflex Sprinter Tubular Tire is available in a 700 x 22mm size and it weighs in around 225g. The tread is Black and the sidewall is Gum colored. This gives you a bit of a classic look in a thoroughly modern tire. Please note that this tire is sold individually, and that it does not include adhesive.
