James and Nick of Boo based out of Fort Collins, had an entire slew of interesting bikes in their booth, their mainstay being the combination of bamboo and carbon fiber. The most interesting on display was the wild looking Boo Glissando townie concept bike, which ended up getting the Award for: Best alternative material at NAHBS.
They used laminated bamboo as a natural shock absorber in a frame with a titanium backbone.
They also introduced a fat tire bike named the BOOlossal, which was constructed with larger than normal bamboo tubing to deal with the higher torsional loads from this type of bikes. They used a Gates CenterTrack drive system coupled to a Rohloff rear hub, which should prove to be an interesting combination. I assume the fork and bar/stem combo were made by Black Sheep, since it looks like their design?
Alex Cook of A-Train out of Minneapolis, had a really nice steel singlespeed on display. The bike is a combination of Columbus Life for the rear triangle and KVA stainless for the main tubes.
I liked the lugs, and the little swooping section at the rear, along with the pretty green glittered paint job. It’s spec’ed with White Industry cranks and hubs, a painted Niner carbon fork and weighs in at 20 lbs.
The Valkyrie is bizarre and wild looking downhill bike. The bike has 180mm of travel, comes in 26″, 27.5″ and 29″ wheel sizes, and is constructed with KVA and 17-4 stainless steel tubing.
The entire seatstay, shock assembly, pivots and drivetrain are interesting design. I wonder how it rides?
