The superlative Cross Country and Marathon competition tyre. Centre lug height and arrangement are designed for lower rolling resistance. Shoulder lugs have a serrated surface - 'Off-Camber-Grip' - for better cornering. 'Wide-Gap' profile design ensures better grip and promotes easy self-cleaning. A steeper carcass angle makes the tyre more flexible and supple reducing rolling resistance even further. Speedgrip compound, a mixture of Qulaifier and Offroad-Racing Compound, keeps rolling resistance low yet guarantees grip and stability.

The Racing Ralph's supple, light Evolution carcass with low, borad triple-compound tread is still outstandingly fast and responsive. Also, unlike many superlights, it really is the size it says it is, which adds big float and comfort.
The tread hooks up consistently in far worse conditions than you'd expect it to. It's smooth into corners with an easily controlled slide if base grip is exceeded, and it's predictable over roots and rocks. The fast-cleaning tread means you can even leave it on the rear all through winter if you don't mind getting tail happy occasionally.
MBUK rating: 7/10 - "Super-fast, super light and with startling grip"
