R4 320

Brand: Bontrager

The Bontrager R4 320 is a tube-type road tire built on a 320 TPI polycotton casing, prized for suppleness that approaches a tubular's ride quality. It is offered in a single size, 700x25C, at 230 g, with a slick tread, 60a rubber compound, soft bead, Hard-Case Lite protection and a maximum pressure of 110 psi. It remains a lightweight, everyday clincher rather than a race-day tubeless option.
