Ek … sure it doesn't have the bite of a Minion, but it doesn't have the bulk either. I rattled down Fyrish earlier on them … the only skid happened when I turned 90 degrees at speed in Novar where they'd newly spread gravel on the path up to the estate office. Both wheels went together, but it was easily controlled.
I also have a pair of Larsens which are fabulous too. I've thought about Larsen F/Crossmark R, but have never got around to it.
2 DH racers I know have them on their (7 inch!) XC bikes and rave about them. I hear they are massive on the continent. I know Gordy wasn't so keen, but he tried the 2.25. I reckon the 2.1 has more bite that the bigger tyre. The same thing is apparently true of SB8s.
Try them … they don't look like they will work, but they do. Happy to give you a turn of mine. They're on light rims (5.1d) but the hubs are bolted.
