I run a 2.1 on the rear & it's light & fast.
Very loose in corners at high speeds in unpacked areas. Doesn't have much of a footprint. Might try a 2.25 in the future.Overall Review: Still undecided on this tire. Seems it would be fine on packed surfaces w/ minimal sand, rocks or pine straw. I run a 2.25 Nobby Nic on the front & this on the rear. It's definitely a fast combo, but trying to stay in control at speed, on loose terrain, is a challenge all in it's own. Gonna try a wider version to see if the problem persists before putting a Nic on the rear.
