Introducing the Tyaughton: our new 29’ hardtail comes in steel, can run a 150mm or 160mm fork, features advanced geometry and incorporates an unapologetically high level of construction with fully custom tubing. The Tyaughton is everything you need for a super capable and playful hardtail trail bike.
*Due to supply chain challenges in the industry, shipping of complete bikes to you can range from immediately to up to 4 months due to vendor parts availability and delivery times to the Knolly warehouse, we will be in touch with your order timelines once your order has been processed - thank you for your patience and understanding*
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.
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.
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.
