The New Knolly Hardtail

Introducing the Knolly Tyaughton Hardtail. Our new 29’ hardtail comes in titanium or 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.

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 Knolly Tyaughton Hardtail features a 64.5 degree head angle with a 150mmfork (or a 64 degree head angle with a 160mm fork) which makes itcapable on both technical up tracks 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 chain stay 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 backend of the bike is engineered for compliance and delivers a supple ride.

Materials: Titanium and Steel

Taking what we learned from our Cache gravel models, the Knolly Tyaughton Hardtail was planned from the start to be offered in both titanium and premium air hardened steel. The primary focus was on performance and these are hands down the two best materials to use to achieve this goal.

Tyaughton Steel

The Tyaughton Steel frames use air hardened steel because it can be manipulated before welding and then heat treated to give high strength and durability. Our steel frames are also ED coated to ensure maximum corrosion resistance and painted with tough powder paints for longevity. All our steel tubes are butted so that thewalls are thicker where it’s welded and thinner in the middle which reduces weight while ensuring that the tube ends are incredibly strong. This model is designed to be affordable while performing at the highest level possible.

With additional features and significantweight savings, the Tyaughton Titanium is the ultimate expression ofmountain bike hardtail performance.

Custom Tubing

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

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 tube set to ensure riders of all sizes can get the maximum performance gain possible from this material. Large frames get the largest diameter tube set to compliment larger statured riders, while smaller frames get reduced diameter tube sets to match rider size and weight while providing matching compliance.

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 chain stay yoke.
