NOT TO BE USES AS TUBELESS

The Challenge Record Open Tubular Clincher Tyre is designed for those seeking an advantage in triathlons, time trials and on outdoor velodromes without the hassle of choosing a full tubular offering.

Featuring a high 300 thread count casing and a finely knurled tread pattern for superb traction, the Challenge Record Open Tubular delivers excellent control and race winning speed.

The Record Open Tubular tyre also features a lightweight Aramid bead for compatibility with ETRTO standard clincher bead rims and a high thread-count, plus a SuperPoly casing, which increases suppleness and reduces rolling resistance compared to regular Poly casings.

What's an open tubular?

An open tubular is constructed using the same casing and tread materials and process as a tubular, but instead of sewing the casing together (closed), the sides of the tubular casing are folded around aramid fibre cords to produce beads.

This ‘open’ design performs like a tubular, yet conveniently mounts like a standard clincher tyre.
