Challenge has announced a new road tyre, the Criterium RS, said to offer \u201cthe perfect mix of speed, grip and durability\u201d.<\/p>\n

Announced to coincide with Eurobike 2022<\/a>, the handmade road bike tyre<\/a> has a 350 TPI casing and a new Smart Prime Compound.<\/p>\n

Challenge claims these features help make the Criterium RS comfortable but also \u201cone of the lowest rolling-resistance tyres in the market\u201d.<\/p>\n

The tyre is compatible with hookless rims and comes in either 25mm or 27mm widths. It has an \u20ac84.90 \/ $94.99 retail price and is available with white or black side walls.<\/p>\n

Jose Mazza of Challenge said tubular versions will be available in the future.<\/p>\n

The 350 TPI Corespun Cotton casing of the Criterium RS tyre is said to create a supple tyre with optimised weight and comfort.<\/p>\n

Challenge says the tyre\u2019s low rolling resistance is due to its Smart Prime Compound, which is new for 2022.<\/p>\n

The compound isn\u2019t only good for rolling resistance, according to the brand. It is said to increase grip in dry and wet conditions, as well as improving puncture resistance.<\/p>\n

Challenge says the compound\u2019s mix of natural rubber, chemicals and an un-specified proprietary formula means it is 50 per cent more puncture resistant than other compounds on the market.<\/p>\n

There is also Challenge\u2019s PPS Ganzo puncture protection system between the Criterium RS\u2019s tread and casing. This is said to improve puncture resistance while ensuring the tyre remains supple.<\/p>\n

If the casing and compound haven\u2019t, the tread on the Criterium RS makes Challenge\u2019s intentions for the new tyre clear.<\/p>\n

With a slick line in the middle and grip on the exterior edges, the tyre is designed for speed but also to provide grip in wet weather.<\/p>\n

This isn\u2019t too surprising given Challenge is known for its gravel tyres<\/a> and cyclocross tyres, which Tom Pidcock used on his cyclocross world championship bike<\/a>.<\/p>\n

Hookless compatible<\/h2>\n

Challenge says the Criterium RS tyre can be run tubeless<\/a>, is compatible with hookless rims and is compliant with existing ETRTO and ISO standards.<\/p>\n

The tyre has a new Zylon bead. Challenge says this means the tyre has improved load capacity and will not stretch.<\/p>\n

There is also a chafer bead protection strip. This is said to enhance longevity by reducing the effects of chafing if the tyre is fitted to hooked rims.<\/p>\n

The chafer bead is black and Challenge says the contrast in colour (we\u2019re guessing it means if you have the white version of the tyre) helps you see whether the tyre is seated properly on a rim.<\/p>\n
