The frame's down tube is a sealed chamber acting as an expansion tank for the Adaptrac System. This tank results in faster fill times and warmer regulator temperatures. The massive 1.50" straight head-tube is the stiffest available.
Lets face it. No one knows how such large tires affect the behavior of conventional rear suspension designs. So, lets not go conventional. Using proven linear bearings, the Zeppelin uses Linear Axle Path Technology. This allows the rear axle to emulate the same path as the front fork. When compressed, the bike acts as one.
SRAM's XX1 cranks, modified to 100mm BB spacing drives this beast. It's simple single chain-ring and massive rear cassette offers all the gear ratios you need.
The rear Adaptrac hub is a wide 170mm giving ample chain-tire clearance. The frame is a symmetrical design, unlike some fatbikes that curve the stays to one side.
The Cane Creek Double Barrel is arguably the most adjustable rear shock on the market. Perfect for tuning in the right low and high speed compression and rebound settings.
The rear suspension uses two shafts situated 75mm apart. A welded rear triangle slides up and down on these shafts using recirculating ball bearings.
