I got everything together, so here they are.
First is the bike I bought from guero.

I sent the original fork to Marzocchi to get the lowers changed, along with a 20mm thru-axle. It also has a white handlebar and a new seat. Right now it's wearing Crank Bros. 5050XX platform pedals.
Then there's my new Kona Hoss. My old steel Marin XC bike was having problems with the brakes. Getting them fixed or replaced would cost nearly as much as the Hoss on closeout from Wheelworld, so I treated myself.

The spec isn't the greatest, but I should be able to replace stuff as it breaks, and eventually I'll have a pretty hooked-up, burly XC bike.
Then there's my school commuter, a Bianchi SISS. This bike never sees dirt.

This one is sporting the kickstand I asked for advice on.
So that's it! I forgot to photograph my Titus Switchblade, but that one's currently being fixed up anyway. I just installed the Fox Float R that I bought from STR, but it needs a few more things to get back up to speed.
