Featuring 220 TPI casing and weighing just 175 grams, the most impressive thing about the R4 Road Tyre was the grippy, confident, adhesive performance.

Test ridden by Matt P, who began with a great a deal of doubt over how it would match up to the Michelin Pro Tyre and the best selling Continental GP4000 S, the R4 Road Tyre was a pleasant suprise.

The 220 TPI casing provides a great deal of suppleness, on a wet day the R4 tyre inspired confidence and rolled well on the flat. Whether the Bontrager 'Aero Wing' aerodynamics were the cause - allowing a smooth airflow over the tyre / rim interface - or not, the tyre rolled well.

The only concern was puncture on the second ride, but this may well have been more due to the roads being ridden than any defieciency of the tyre, the tyre is fitted with integrated sub tread puncture protection.

Upon riding the R4 Road Tyre delivered a fast rolling, confident, supple and grippy ride.
