The Tyaughton Titanium has been created from a dream material. Titanium is light, stiff and long lasting, providing a premium quality ride for discerning riders. With additional features and significant weight savings, the Tyaughton Titanium is the ultimate expression of mountain bike hardtail performance.

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 Titanium features a 100% proprietary Knolly oversized tube set with all frame tubes tapered, butted, bent and formed to the material’s limits. This allows Knolly to achieve subtle Knolly-esque frame design emphasizing stability and compliance. This model also features a unique frame size specific tubeset to ensure riders of all sizes can get the maximum performance gain possible from this material. Large frames get the largest diameter tubeset to compliment larger statured riders, while smaller frames get reduced diameter tube sets to match rider size and weight while providing matching compliance.

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.

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.
