The new Trigger is the fastest of the three with a progressive central file tread similar to what we've seen in Clement's LAS but with aggressive side knobs for reassuring grip in corners. Moving up a notch on the grippiness scale is the intermediate Tracer with a tightly packed array of low profile, rectangular knobs similar to Specialized's Renegade mountain bike tread. Finally, there's the aggressive Terra pattern with taller and more openly spaced knobs for low-traction conditions like loose gravel, snow, and mud.
All three tires are built with 260tpi polycotton casings, glued-on rather than vulcanized treads, and single-compound 62a rubber, giving a balanced mix of suppleness, grip, and tread life. In keeping with the UCI's recent technical rule changes, stated casing width is 33mm and according to Wells, actual casing dimensions will err on the smaller size to guarantee they're legal. Tucked inside each tire is a latex inner tube while a nylon breaker beneath the tread aims to ward off punctures. Claimed weight is around 400g for all three designs.
When Specialized's new offerings are taken in combination with other bigger manufacturers getting into the 'cross tubular game like Schwalbe (and maybe even Continental), things are looking good for racers seeking high-end options that are easier to source and a little less care-intensive.
Don't get too excited just yet, though, as Specialized says its tires won’t be readily available until next season. There's also no word yet on if we'll see these tread designs in clincher form.
