Anyone thinking of building up a Mid Fat bike this year. I have a carbon 29er with rigid forks just laying around. I’m looking to get my hands on some WTB Asym i35 650b rims. The 27.5 WTB Trailblazer 2.8 are looking real good.. Schwalbe has Nobby Nic’s and Rocket Rons coming out in 27.5 with 2 different tire sizes of 2.8 and 3.0. Looking real nice.September 29, 2015 at 12:15 pm #807123
That sounds like an awesome option for winter riding. I have a fat bike, but I am already looking into these for my riding buddy. I am pretty sure he’ll be all over this.September 29, 2015 at 1:24 pm #807126
Matt informed me that the nics will not be available for some time yet. If anyone knows of a 27.5 in 2.8 to 3 as per above please let me know.September 30, 2015 at 1:14 pm #807160
I saw the WTB Trailblazers mounted to the Scraper rims the other day and I have to say it looked weird. The tread patter is narrow on the tire. The tire was fairly fat on the wide rim (45mm internal) but the tread honestly didn’t look wider than a 2.4. The sidewalls bulged out way past the tread, which seems like badnews on anything other than straight line rolling. The Schwalbe tires look really good and are quite light.November 16, 2015 at 9:20 pm #808126
I never ended up building any wheels for my mid fat. I built up my old carbon bike with rigid forks. I just tested the bontrager chupacabra 29×3.0 today. Tire is BIG lol. I left a little auto steer when riding at first going down a hill. Running around 13psi feels real good. The front end just floats over bumps. Endless grip. Meet the skinny mid fat build.

The tire fit on a Manitou tower 29er fork. Real tight but it rolls without hitting anything. Hmmmm.

I kinda sorta wanna do this with my rigid Unit frame. Would love to hear more as you get more experience with it. .November 18, 2015 at 9:48 am #808147
My winter MTB set-up has ridiculously tight clearance, and it’s never been a problem, because
1) zero mud clearance is okay on frozen ground.
2) snow clearance, IMO, is not a thing.
3) winter riding, especially on snow, isn’t conducive to big lean angles or hard cornering that can cause tire rub, even with regular QR axles.
4) very low winter tire pressures mean slightly less tire volume.
So yes, a fat bike frame with three square miles of front and rear tire clearance would be nice, but I’m not missing it.
