Designed around a go anywhere theme, the Karma is can take on the toughest of trails and inspire confidence in the rider. 

They handle most conditions really well, we found them excellent both on trail-centre hard pack and on slippery rooty single track with predictable levels of grip.  The secret is the low profile square tread pattern linked to a very sticky tread compound.  We tested the 1.95 tubeless version and found it shed mud really well to maintain its grip with no punctures at all.  If you like a little more comfort opt for the 2.1 but in wintry conditions a smaller tyre will generally cope better with mud. 

All in all an excellent all round tyre.  Price €38 from all good bike shops.
