It was brilliant on Dartmoor. The guy I was with was on a Karate Monkey with 2.4 tyres, and he was having to pedal to keep up with me when I freewheeled on downhills
It climbs really well, I’ve got a 36 on the front and an 11-34 cassette. The only problem I’ve had is with a really slow, technical uphill when the wheel size made it oversteer a bit. The grip on loose climbs is phenomenal. I’ve made it up stuff that I’ve never done on other bikes.
No magic weight reduction in the wheels! The rims are surprisingly light due to the cutouts and I’ve got the 120 tpi tyres, so a bit lighter than the standard 27 tpi ones..
I was stunned by how fast it rolls.
In comparison my alfine karate monkey is about the same weight, with smaller tyres and it was simply no match when it came to ease of pedalling, the Krampus out-rolled me on every descent, both on and off-road.
There were also bits of moor I was really struggling on that tom on the Krampus just seemed to to roll over with minimal fuss.
If I could get one, I would.
