just thinking, like: fatbikes are 26 inch wheels plus massive tyres so a normal to biggish tyre on 29er wheel should fit fine, should it ?
Rear hub is what, not 135 I assume
BB shell ?
What else is abnormal ? (front 135 ?)

niche amalgamation question - 29ers on fat frame ?

If its a 135mm rear the dishing will be different.
some fatbikes have 170mm rear hubs which would run a 29er rear with no probs.
I've run a rear 29er wheel in my fat bike fork.

170 rear ?
I'd expected 150 or 143.7683 (or whatever that new one is)

135 or 170 depending on which frame you choose. The new On One is 170 apparently.

Cheers. OK, are the 135s so weirdly dished that it'd be a new wheel anyway (if so, I appear to be out, unless std hubs can be spaced to 170 somehow)
what's the BB like - can't possibly be standard and takes "normal" cranksets, can it ?
(Oh I know it'll all be on google, but this is nearly useful to others too)

Typically 100mm BB, choice of Square, ISIS or buy new external BB cranks.
Wheels would prob need rebiult with new spokes i imagine.Depends what frame its for...

There's no hard and fast standards for fatbikes but most have 100mm BB's, 135mm front spacing and either 135mm offset rear or 170mm none offset rear spacing.
I'd imagine that it'd be quite difficult to build a 135mm with enough offset on a standard 29er rim.
If you look at the spoke holes you can see how offset the rim is on a 135mm rear end.

Look up Mikesee's custom moots thread on MTBR. He did the 29/fat convertabike a while ago, in style too.

The offset is only 6mm I think. There is one offset 29er rim by velocity, I think a UK fat biker has done it-Jonny someone?
I looked into it myself ap it does seem to make sense to double up...
