'no more noodles'

Time for some proper northern engineering.

Rockstop's complex geometric design has brought some science and engineering to the trails for the tubeless-ready wheel. It's made of tough high density polyurethane, and is focussed solely on preventing punctures and rim damage. It actually looks as though it should do what it's supposed to.

Designed and manufactured in the English Lake District, Rockstop is the result of a year's collaboration between the guys at Grizedale Mountain Bike Centre, who drove the project, and Urofoam Ltd - specialists in polyurethane engineering, from their factory at the mouth of the Duddon Valley.
