Had a new one on the rear for about 500 miles which came on the bike when I bought it a few weeks back. (I've now changed to something chunkier for off-road.) They so look skinny, but bike handled great on it and felt very sure-footed. Off road on hard packed (but a bit loose) 4x4 tracks I was amazed how much grip there was for a tyre that looks like a road tyre. Wouldn't want to see any mud with them on though. If I was 90% road-riding, or knew my off-road would be very sedate and predictable, I'd fit them without hesitation.
