This build was a continuation of my Mesa Buggie build from last year's 2016 Off Road Build Off. This year I added a 6 spd freewheel along with a vintage Shimano Eagle rear derailleur and operated by a late '80s Shimano thumb shifter. That's on the 'go' side. On the 'slow' side, I added an Avid BB7 disc brake kit for a rear brake, along with an adapter to mount the caliper to the rear stays.

Here is the build thread from the original build, Mesa Buggie ORBO 2017:

And the build thread for the modifications during our WBO 2017:

Why a fat tire on the front, but not the rear? I don't ride off road so I know little about the technical aspects of the sport.
Hey, Josh. With a tire of that size, 26 x 3.8 on the front, and run at a low p.s.i. say around 7-9 psi; the tire will conform and roll over bumps and uneven surfaces in the trail. Instead of bouncing off of them.

The whole purpose of suspension is to keep the tires on the surface to maintain control and traction. So, with the low pressure in the large volume tire, and the wide rim which helps disperse the 'bump impact' of the terrain, you won't flat as easily.

It will be a much smoother ride than say a 26 x 2.2 standard mountain bike tire; which by virtue of the narrower rim and small contact patch on the ground has to run a higher psi to avoid flatting and rides much harsher, albeit probably faster.

The final reason in this instance is, the 1951 Schwinn frame barely contains the 26 x 2.4 knobby tire I have in there, and would never fit a fat rim and tire combo like on the front. The front fork is specific for the fat tire.

I remember having a set of Specialized brand mountain bike tires in late 90's. The front was a knobby 26x2.2 and a rear 26x1.9 which had a very mild almost knob less profile. They rode amazingly well.

Awesome! :thumbsup:

I remember BMX's running 1.95 fronts and 1.75 rears back in the day. More grip and cushion on the front, lower rolling resistance on the rear.
Yeah, Luke. It is def a concept carried over from those bmx days. Only taken to a bit more of an extreme....! :wink1:

Thanks for the info!

Killer klunk and I like that fat front tire with the ridged fork that's is the shock absorber . Looks like a great place to ride & you mad cool video the sky was perfect. watch out for them rattle snakes . I bought a new 29er mnt. Bike a couple years ago . On the second time I rode it I ran over a 5' rattler . I took a hard crash & folded the front wheel when I flew off the trail & landed in the ditch . It was a bad day but I guess it was a good day because at least I didn't get bit .
Enjoy that AZ winter bro ....

That's a positive attitude to crashing if I ever heard one G! Haha! Yeah, it's too cold for the snakes yet. But the cactus like to reach out and bite ya once in a while.

If you're like me, the first thought after a crash is "Is my bike okay?" Then I take inventory of my body! :21:

Lovin' the AZ desert. Thanks man. Had a new adventure yesterday...Jeepin' with a buddy and a bunch of his Jeep pals.
