Interbike is over, so Surly released the full geometry of the Krampus.  And it looks good.

The Mukluk has proven to be my favorite bike ever, not that I’ve had many.  All the ones from the last six years are listed above, and my assessment that the Muk rides like a rigid, fat Lev with a lower BB is borne out in the numbers.  The Lev occasionally felt long and clumsy, but my style adapted to it and ever since the Monkey has felt a bit nervous.  While it’s impossible to disentangle the overwhelming influence of fat tires on the Muk’s ride, it has comfirmed that a longer bike, with a BB a bit higher than the Monkey might well be ideal.

I had a feeling it would, but the numbers confirm that I want a Krampus.  Maybe in the spring.  For the moment such things will take a back seat to ski gear and fatbiking.

The Moloko bars and, especially, Krampus t-shirt are good too.
