2011 new street bike PROTOTYPE!!

note: this bike is just a prototype
the Gunpowder will still be our current Dirt Jump/Street Cr-Mo frame
OK
it's time to announce our top secret DJ/street bike
maybe some of you had seen it at our booth in Interbike
the name of it remains unknown
and so does other spec
but what i can tell you is
this babe runs a 83mm bottom bracket and 150mm rear hub
which is a standard for DH bike
yeah we know you're curious about this
why we do this?
the reasons are below

1: running a wider BB and hub can offer more strength
2:DH cranks and hubs had been very well developed, that makes them so light and strong
3:the most important, we can make the chainstay super short without any compromise

so here's what we've got


Hydro form chainstay,370mm(14.5") chainstay
with 26X2.6 tire clearance and 36T sprocket clearance
fit's almost any tire even a worm hooker( you know what i mean)
of course you can run smaller tire and smaller sprocket with this kind of clearance
but you can't go big with small clearance
the only way can make it shorter is to cut the BB in half or run a 24"
and the 24" version we're working on could reach 345mm(13.5")



front bent seat tube allows the seat goes superlow
using a pivotal seat could reach to the bottom



Hydro-form down tube
saves some serious weight



tiny little dropout but still with integrated chain tensioner
just like Gunpowder but much lighter




and definitly it runs Skull Drives
