I figured you Surly only folks would want to know this too, posted it on the Fatbike forum just now....
Got the little beasts in this afternoon.
Had a few odds and ends to wrap up first, but got right down to business as soon as I could. Laced it up offset, turn out I could have gone symmetrical, which I will before riding it, just because.
I've had a huge number of folks wanting to know, will the 29x3 Knard/Rabbit Hole fit a Lefty.
More importantly, will it fit a conventional Lefty, as opposed to the custom offset jobbers required for Fatties.
Yes, they work. Just fine.
Clearance may be a tad close for some, but I think most will find it more than adequate, assuming a nice stiff built wheel.
Travel clearance will need to be on a case by case basis, but the wheel fits the chassis, so the rest is up to ya'll.
In this case, I used a moldy oldy 130 Max. A to C is 510, Krampus fork A to C is 485. I can squeeze about 90 mm out of it as it sits.
So on a Krampus frame, you'd be looking at less travel, a 490 A to C fork like a Speed 110 would likely net around 60 to 70 mm. Respectable, and close enough to keep handling neutral.
Or, toss a longer fork on your bigger bike, and go to town with 100+ using a 140/520 A to C.
