The Knolly Tyaughton Steel, our second hardtail mountain bike model, comes in steel, which is heated-treated to give it high strength and durability. It can run a 150mm or 160mm suspension fork and features advanced geometry. The Tyaughton Steel hardtail is everything you need for a super capable and playful trail bike.

Steel

We chose air hardened steel because it’s malleable which allows us to craft the tubing to the exact spec’s we need. It’s also heat treated to give high strength and durability. We also apply an ED anti-corrosion coating on all our tubes so that the Tyaughton is ready for all weather conditions.

Progressive geometry

The Tyaughton’s geometry has been designed from the ground up: we’ve utilized our extensive knowledge from our full suspension line-up to ensure that this bike rides as competently as our suspension models while still being incredibly balanced across all types of terrain. While conceived as an “all around, do everything bike”, the Tyaughton is extremely progressive and suited both to big days in the saddle as well as shredding your local trails.

The Tyaughton features a 64.5 degree head angle with a 150mm fork (or a 64 degree head angle with a 160mm fork) which makes it capable on both technical uptracks and steep descents. The seat tube angle is ideally positioned at 75 degrees to deliver an efficient climbing position while also ensuring that the rider’s hands and knees are comfortable during epic days. The front end of the bike is long to increase room in the cockpit and allow the rider to stretch out. The chainstay is modest at 427mm, blending stability and maneuverability. It’s long enough to give the bike optimum balance across its wheelbase but short enough to get out of your way when you need to get the front end of the bike up. The back end of the bike is engineered for compliance and delivers a supple ride.

Custom tubing

The Tyaughton Steel features a frame size specific butted, bent and formed tubeset that blends production level repeatability and precision with a craftsmen level of manufacturing.
It features a size specific tubeset (small frames don’t get the same tubes as the XL and vice versa) and incorporates many of the titanium frame features including integrated ISCG05 chain guide tabs and a unique head tube.

In addition, both Steel and Titanium frames have a unique head tube shape designed to maximize strength to support forks up to 170mm. Tubesets flow into custom CNC machined dropouts, yokes and access ports (Titanium-only) so that stress risers are minimized. Even the included ISCG mount attaches cleanly into a recessed CNC machined pocket on the chainstay yoke.

157Trail

We feature 157Trail rear hub spacing which uses the wide flange 157 hubs with 73mm BB shells. This spacing provides the most options for tire size and can easily clear tire widths up to 2.6. With 157Trail, heel clearance is exceptional and chainring clearance remains huge at 36T.

Human Centric Sizing

We have always believed in human centric sizing and design our bikes to deliver optimal reach, standover height and geometry for a broad range of riders.
