PRESS RELEASE: Knolly BikesIntroducing the Tyaughton: 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 GEOMETRYThe 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.
MATERIALS: TITANIUM AND STEELTaking what we learned from our Cache gravel models, the Tyaughton 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.
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 the walls 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.
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.
CUSTOM TUBINGThe 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.
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.
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.
ADDITIONAL FEATURES:Titanium exclusives:
CNC engraved head tube
Full Internal dropper post routing with an access hatch on the underside of the down tube
Brushed finish
Fully 3D formed seat tube (butted, tapered, bent and formed)

Dropper post insertion length: 175 Small, 175 - 210mm Medium, Large and X-Large
GEOMETRY/SPECS: knollybikes.com/AVAILABILITYThe Tyaughton is available in two material options including titanium or steel, with the steel version available in Container Red or 510 Green. There’s four sizes to choose from - small through extra-large - and multiple build kit options. Full bike prices start at $3599 USD for the Steel and $6099 USD for the Titanium. Frame only prices start at $1099 USD for the Steel and $2999 USD for the Titanium. Both models are available to purchase now from your local Knolly dealer or online at

A 27.5, forward geometry 120-130mm ti HT would be a ton of fun
27.5? You clearly wouldn’t buy this, “but”.
You are looking for entirely different bike.
I've found that a full suspension even with cheap shocks, if it has moderately decent geometry, is faster than the best aggro hard tail. Its also very much not fun to ride an aggro hard tail at full speed down a really rough trail. I love my hard tail, but not when trying to race my friends on their enduro bikes down chop, moto holes, and rock gardens. Because of this I think the uber short chainstays and head tube angles steeper than 65 degrees is the best way to go. You don't want to go super fast on them, so make them feel almost like a dirt jumper so you can play with the trail your on.
Do you think providing that info would result in more than single digit more bikes sold, if that?
Otherwise a good looking bike. Could definitely be slacker. I think hardtails need to be about 1-2 degrees slacker than a comparable FS bike.
Completely unrelated question, I noticed the serial number on the BB starts with OR, which is the same as my RSD bikes. What does that indicate?
I have a rear hub 148x12 and I bought the kit from Problem Solver to adapt it to 157 supet boost. Work perfectly well!
Knolly frame way more rigid than my Sentinel alloy... frame it self or superboost I can't tell!
I found this document from Seven Cycles, also some good info in it

China Ti. Is has exactly no reputation . Litespeed will be glad to pour over every minute detail of the 3al 4v aircraft certified titanium. I think they use water jet cut 6al 4v ti for drop outs.
At this investment I expect details. Which any custom frame builder is happy to divulge.
Bring on the hype!
Sorry Transition you guys rock but generic Ti. ? Labeling a steel frame set as air hardened? That's it? About as generic and dumbed down as stating it's 4130 . And Reynolds air hardened tubeset is not a 4130 alloy.
A bit more digging they also compeat with the world market for steel and aluminum alloy . For a whole 4 years. Thus my suspicion of durability . Titanium coil springs from China were a joke. Close to same weight as steel . Because there was no certification .
In the past when most frames were hard tails made of steel or titanium$ . The type of tubeset and how it was built reflected the cost and the prestige of the frame.
Air hardened steel tubes are superior. I just have to accept the Chinese lack the romance of some 100 year old company , English or Italian well established tube set .
Cheers!
62 degree HTA, Steel HT designed around a 180mm fork. Released almost 3 years ago now (Feb 2019).
The Marin El Roy is a close second (63 degree HTA), as is the Kona ESD (also 63 degree HTA). Both of those are steel afaik. They are not as slack, but also have less fork travel, so they may be pretty close while being ridden.
-Just as heavy
-Price point is approaching parity
-Won't pedal any better
-Won't be more playful / is longer
-Isn't going to be faster
-Will beat you up
Better yet, anyone ridden both?
I would say technically wise EOL6 (offset lacing like connandoel, GG, sentence) makes more sense rather them adding width, adding with is like lets add more carbon to make frame better, rather lets optimize performance to the max
