Continental GP4000S2 Road Tyre 700c 25mm - Unboxed


The legendary GP4000S tyre has been updated to include a broader range of sizes which now also benefit from the latest cutting edge rubber compounding available in the bicycle tyre industry - BLACKCHILI.


Featuring lower rolling resistance, higher mileage and maximum wet weather grip, riders who already use the GP4000S will continue in the knowledge that they are riding the best all-round performance road bike tyres that money can buy.  These tyres are so good we sell all of our clinchers with them!
