Bontrager R4 320 Handmade Clincher Road Tyre
For a road tyre that ticks the boxes for road and criterium racing, the Bontrager R4 320 Handmade Clincher Tyre is ideal, with durability from the 60a compound, paired with sports-performance lightweight construction materials.
The tightly knitted 320 TPI allows higher tyre pressures to be achieved resulting in a lower rolling resistance with faster speeds obtained while feeling confident from a high level of grip. Punctures are reduced with the addition of the Hard-Case Lite tread integrated within the tyre mould, without adding any extra bulk.
Additional reinforcements are featured with flexible polyamide synthetic fibres to offer incredible strength and durability, while the strong sidewall structure adds protection right up to the tyre bead.
