More info

Outstanding quality, handmade, high tread count tyre, for road use.

PPS:

The Puncture Protection System is a special fabric placed between a tire's tread and casing to increase resistance to punctures.
Some tires designed for use on rough roads, cobbles and gravel receive a second layer of PPS between the casing and the inner tube we call PPS2.

Rolling Resistance 2 - HTU

The benefit of being super supple is that the latex tube (used in all Challenge high-end tubulars) helps our soft and supple Handmade tubulars and clinchers to potimally deform over road and trail imperfections - greatly reducing rolling resistance. The latest published tests by Josh Poertner (ex-Zipp and current Silca tech guru) show that you save up to 3 watts per wheel just by changing from a butyl to latex inner tube. The latex tube compliments our soft casings and treads so that when the tire impacts road and trail imperfections, instead of bouncing, sending shock waves up into the rider and forcing an extra burst of energy to overcome the extra rolling resistance, the tire absorbs the bump and rolls over it smoothly, almost as if it wasn't there.
