Chris DeKerf at one time welded frames for Rocky Mountain.                           If you ever see an old Altitude, you can see very                          similar construction techniques to the current DeKerf                          frames. And he seems to be pretty successful because now                          he's branched out to make an aluminum frame and an FS                          frame. 
[edit] after a long absence sending all his frames off to Europe and doing wet-booth work for Rocky, DeKerf is back!   rejoice and revel in hand-built canadian awesomeness!
                   
Team SL- This bike would confuse the heck out                          of a mountain bike magazine editor.  "A long                          travel fork?  It must be a freeride hardtail...                           But where's the riser bar?  It can't be a race bike                          with that fork on it..."  Luckily, we can ride                          anything we want and ignore the classifications some people                          seem to need to use. 
                       Is it just me, or does that color say "standard                          Army issue mountainbike?"

Generation - How do you get yourself a handbuilt                        DeKerf, and still be able to afford to eat something other                        than Ramen noodles? You get the Generation, more or less                        the same frame, but cheaper components.
 Team ST -
Team ST - This is the Team ST with Ti chainstays.                         It's really too bad that Dekerf seems to favour Rock                        Shox, because this bike with a Marzocchi would rule.

Team                      ST  - Well I'm really sorry to say this, because I'm sure                      you spent a lot on that custom flame job, but I don't think                      I've ever seen a good flame job on a bike.  But maybe                      it's that butt-ugly Shimano crankset and weak Rock Shox fork.
