My virgin powder tracks after the Die Hard party. The Trek 520 rides great in powder, cyclocross tires make all the difference, no slip at all on powder and hard pack.
What a beauty. That is Brendan's Seatpost and seat, I managed to break my seatpost tightening a bolt at the party and had to borrow his.
My winter riding regalia, snowboard helmet & goggles, 3 days worth of stubble, and my touring Trek 520 with cyclocross tires. Check out those knobs. Snow was two inches above the rim, navigated through the mire without incident.
