Knolly’s Tyaughton is their air hardened steel hardtail built around modern progressive geometry and custom steel tubing. The Tyaughton’s progressive geometry with its 64.5-degree head angle (150mm fork) firmly puts it in the more aggressive camp without losing the ability to ride all day. 427mm chainstays keep the rear simultaneously snappy and stable, a happy compromise. Not to mention the incredible versatility of the Tyaughton due to its ability to utilize forks from 130mm-180mm. This allows the Tyaughton to be built up as a singletrack ripper or an enduro specialist. Custom steel tubing and size specific tubing ensures that the frame is fully optimized for a variety of riding styles and riders. Knolly’s choice of steel for the Tyaughton offers a springy and supple ride quality without compromising on strength or durability—if you've ridden steel, you know. Knolly’s incorporation of superboost spacing in the rear is unique in that they’ve utilized the additional width to allow for larger tires and increased heel clearance for riders who suffer from the flipper foot syndrome. Simply put, the Knolly Tyaughton is a terrific platform for riders who want to build up the ultimate steel trail or all-mountain shred machine.
