Check out the sweetie below. At least half of the snow biking crew that I frequent with is now on or is converting to 9Zero7 (area code of Alaska) bikes from Chain Reaction cycles. This includes endurance specialist and multiple time 24 Afton champ Dan Dittmer who after a first attempt at "trying" the Arrowhead race will be "racing" it this year. Let me say it this way, I work with and ride w/ a bunch of gear-head engineers and all but one of them is on a 9Zero7.
The build below is a full on XX suite w/ Bontrager bits, which enables a complete snow bike to be 26-27 lbf.
