Primo Sentinel 24/25/26 x 1 puncture-resistant tires
The Primo Sentinel combines a narrow, high-pressure profile with built-in flat protection. Under the grooved tread sits a 3 mm LDP insert on top of a dual-layer nylon casing. The tire runs at 125 psi and is offered for 540, 559 and 590 mm rims. The black rubber is described as non-marking and latex free. The tread is directional, so each tire has a set rotation.
