A few shots of Eric's frame (which I'm building while I wait for parts for Derek and some feedback on design from Blake).
Why is it interesting? Well, mainly because it has 425mm chainstays, 29" wheels, and clearance for up to 2.6" tires, while still using a front derailleur and gears. Pretty spiffy. Then add in the fact that it's built for a 135mm fork and has <30" standover, and you've got a pretty unique ride.
To get that to happen, I offset the seat tube forward a bit, used an 83mm shell, and did some dimpling/bending to maximize clearance. Not sure this would work any other way, simply because the front derailleur would cause too many problems.
I also did some goofy stuff (with Eric's approval) with the seat tube that I'll try to take some better pictures of when she's back from powdercoat.
Anyway, long story short, this should be a really fun "freeride" 29er. I'm not so sure myself about the whole idea of 5+" travel hardtails, but Eric likes 'em, so I think he'll like this too.

Smells like a Pisgah assault machine... if this is for THAT Eric.
Wow - pretty wild. Be sure to post a pic of completed bike.
have to ask: what does "offset the seat tube forward" mean?
Nice job Walt, those tough configurations are what "Custom" is all about.
Dude, nice stool...looks a far bit sturdier than mine ;)

Margo -
It just means that instead of the seat tube being mitered to the center of the BB shell, it's mitered so that it sits 5mm forward. Front mech will still work fine, and you get some extra space for the tire/cable/derailleur. I've done it on a number of bikes. If you do more than 5mm or so, you have to start looking at e-type derailleurs, though.

oh good. I was momentarily worried that it was a clever way of saying the seat angle is overly steep...but I know Waltworks would never resort to such mumbo jumbo b.s. cool frame!
