Here’s the interface between the tubeless tyre and the rim. The form we have studied for our rims with Ultra-Fit™ Tubeless technology means that the sides of the tyre mate perfectly with the shoulders of the rim when it is fitted. The result is exceptionally smooth: for whizzing speedily without tubes!
By eliminating every possible movement between the rim and tubeless tyres, all energy dispersion is also eliminated. The Ultra-Fit™ Tubeless wheels well exceed any other wheel fitted with traditional tyres in our tests.
The first installing of the tyre is also made with great ease: two special tracks on the rim groove keep the tyre perfectly in position.
