3" tires? 425mm chainstays?
There are some caveats, but man this thing is going to be fun when it's done! And no, that swingarm won't be attached to this frame. I just bolted it up to play around and give it a little night ride test.

Need. Moar. Detail. Pics. Now.
excellent, the Master!
What is that yoke, a piece of 1/4" walled pipe?
How does the tire behave on the Flow rim?
The SE4? Um, it works great.
I like the Chupacabras on the Flows too, if that's what you're asking.
The SE4? A.B. must be referring to Odawg's report that a Trek Cust Srvc Rep specs the minimum inner rim width for Chupacabra at 40mm. I like how Blakey-Shell, on the same webpage, 'would never recommend going against a manufacturers recommendations on something like this. I ran them on rims with an inner width of 30mm and had no issues.' So you can see what a rebel Walt is at -15 to -19mm. Compare Derby's assertion: 'A smaller tire with wide [Derby] rims works better with more handling stability and cornering traction than large volume tires with similar tread on narrow 30mm rims.'
Tire pictured is a Bontrager SE4 enduro tire.
I have tried a variety of rim widths and at least for me, it doesn't seem to matter much with the Chupacabras. Below 15 psi=sucky. 15-20 = nice. The heavier 29+ tires (ie Maxxis/Surly) may do better at lower pressures since they've got more rubber/casing. I haven't spent much time on them though.
Keep in mind I am not particularly interested in using the tire as suspension. I want the extra cornering traction. Below 15 I just fold the sidewalls regardless of the rim, it seems. Honestly I couldn't tell much of a difference on a Crest!
YMMV, of course.
Caveat #1: not a 3" tire!
Thanks Walt.
Yes, I was referring to the Chupacabras (I didn't realize that was an SE4 in the pic).
I just switched from a 35mm Salsa Gordo in the rear to a 29mm Stans Flow EX. Both using a Maxxis Ardent 2.4, and I feel like I need to keep a lot more pressure in there to keep it from being too squirmy while pedaling or landing small jumps. I was just curious if this was amplified by using the Chupacabra, but obviously you have your suspension doing the suspension-ing so you're not too worried about running it very low.

Very informative and entertaining thread with many credible posters, a misleading title, and sidelights on zealotry and civil discourse. Addresses rim width & material, tire construction, and intended application. Mind your drift patches, ladies and gentlemen.
