Thanks for all your comments! Unfortunately I haven't had much time to ride it as I've been traveling on business. I did manage to take it out for a short ride on some firetrails and singletrack and was impressed by how well the bike handles, especially compared to my previous ride (a full suspension Santa Cruz superlight).
What kind of cage is that? Carrying the wooden theme?
Dman: That is a rosewood-laminated carbon fiber bottlecage. It can be found on Calfee's website at http://calfee.myshopify.com/collections/frontpage/products/rosewood-waterbottle-cage
is the headtube bamboo or carbon?
phallenthoul: The bamboo tubes are joined together by epoxy soaked hemp fiber. In its earlier designs, Calfee used to join them together using carbon fiber, but these turned out not to be very durable.
Do you shop at Red Lantern? If so I saw your bike there, or one that looked exactly the same.
endo: Yes, I ordered the frame through Matt at Red Lantern and he also did the build. Matt also did the builds for several of my other bikes, a Crumpton SL and a Pegoretti Duende.
Beautiful. Is there a chain catcher on there?
crazydachshund: No, it might look like there is a chain catcher on there, but there isn't. The front derailleur is an XTR "Down Swing" derailleur which is less common than the standard XTR derailleur and probably looks like a chain catcher in the photo.
