I'll play.
Custom little Wraith play bike by my buddy Daren in N. Conway NH. Sub-15" chainstays but will fit a 2.4" tire, EBB, super tight. Gets changed up into all sorts of fun incarnations. So wrong it's right.
08ish Sinister Shenanigan. 165/170 rig. (Basically a Devinci Hectik.) Fun bike; used it as my main bike for a pretty long stretch and it's a solid all-arounder that can easily take a lot more than I could ever throw at it.
05/06 Sinister DNA. Frank the Welder built DJ/park bike. I can't begin to do this bike justice.
6" Wraith Sofaking custom w/a scavenger build. Single pivot, idler, floating brake, my current favorite. If you can't have a good time on this bike, you have no soul.
Way old pic, but this frame is still around as a pumptrack/DJ build. Aztech Flying Polack, basically a steel P-bike with horizontal drops and a derailleur hanger. Something another friend built. Ran it as a trail bike for a season and it held it's own. Damn near indestructible; another keeper.
I still have this frame around and plan to revive it for my son (he's about ready to move up from 24" on mtbs). Another Frank the Welder creation, (along with Mickey from Spooky). Usually ran it with an air adustable platform air shock and set up as a trail bike. That turnbuckle gizmo along with a couple different shock mount positions, and a little fiddling, you can run it as a ~110-140 travel and adjust the angles infinitely between high and tight to wicked slack. The most 'tweakable' bike I've ever owned or probably come across.
Still got this 95 DB Axis, Logic 853 tubes, Breezer drops, 1 of 500. about as close as you can get to a real Ritchey. Still got the Spin wheels and all. Could never bring myself to ditch it.
Not mine in the pic, but I have one of these running too. Same color and similar build. 06 Turner DHR
Besides those, the wife has a 06 Enduro, the kid inherited a sick 09 or '10 carbon Mojo SL complete from my father (who went to the dark side and built himself a Niner for his 70th b'day), usually have a few random loaners/giveaways looking to be re-homed, even got one of these collecting dust in the shed - 87 Bridgestone.
