I will have a Nextie Carbon 29 rim, 50mm internal wide , so big std tyre or with the 3.0 Maxxis Chronicle for sale imminently. I was running it on a Hope Fatsno in my Jones with Truss fork but that will no longer be with me shortly.
I can let the built wheel go, it has a Gunsmoke Fatsno and DT comps’s, or the rim.
I ran it with both a normal 29 rear and a Gunsmoke Hope Pro4 attached to a Nextie carbon 50mm internal 650b rim with a wtb trailblazer fitted..Also imminently for sale.
To the question, the Spaceframe rides really nicely with a 29+ front tyre in it on a nice wide rim. rolls nicely and a different feel to the Nate. Much nicer as an overall ride than a std front, more cush, no noticeable rolling penalty and more grip.
I also have a Fat front, Custom Phil Wood high flange SLR 135mm front hub built on a Marge Lite running a 3.8 Nate so can directly compare the feel. I used them differently depending on where I was going to ride. Fat front also going to be for sale.
