PLUS A 27.5x3” tire measures out to a 29” diameter and a 26x3” tire measures out to a 27.5” diameter. Combining them with a 40mm rim, results in the ultimate combination of traction, roll-over and versatility without being too heavy, too bouncy, too tall or feeling lethargic on the trail.   TAPERED HEAD TUBE Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A full 1.5” head tube and steerer would achieve this, but would add unnecessary weight and bulk, and limit stem choices. But a tapered 1 1 /8” to 1 1 /2” head tube serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1 /8” systems.   SHORT CHAINSTAYS The rear wheel tucks in with short chainstays. With a 12x148 rear hub, you’ve got a stiff and responsive rear end.   OUTBOARD CHAIN LINE A 12x148 rear hub with 3mm offset chainrings minimizes the chance of chain to tire contact with short chainstays and “mid-fat” tires without compromising any pedaling efficiency to a wider q-factor.   WHY THRU AXLES? Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, it’s stiffer.  The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It...
