In a world where things are just becoming too complicated. It's time to bring it back to simple.  The Tyaughton takes everything that makes a Knolly great, like the impeccable handling and durable engineered designs. Less moving parts = more riding time and the Tyaughton is ready for anything you can dish out. We've been lucky enough to put the paces with the Steel and Titanium Cache and we can say hands, that is one of the best "feeling" bikes out there. Its smooth, but offers are nice zing when you are putting down the power.
The Tyaughton is no different, it's still a hardtail but offers just a nice feel over chattery bumps and offers a level of flex which helps you find the limit of of traction, rather than pinging off rocks and boulders.  Handling has always been Knoll'ys forte and the low bottom bracket, fully custom tubeset offers another level of confidence.

Taking on the 157mm rear dropout spacing, just like what was used in the Fugitive and Warden - there is plenty of wheelset and hub options available on the market so there is no need to complain about it. It offers another level of rear wheel stiffness and Knolly's implementation offers very little width difference for heel clearance.

The Tyaughton’s geometry has been designed from the ground up: extensive knowledge from their full suspension line-up ensures that this bike rides as competently as our suspension modelswhile still being incredibly balanced across all types of terrain. Whileconceived as an “all around, do everything bike”, the Tyaughton isextremely progressive and suited both to big days in the saddle as wellas shredding your local trails.

The Tyaughton features a 64.5degree head angle with a 150mm fork (or a 64 degree head angle with a160mm fork) which makes it capable on both technical climbs and steepdescents. The seat tube angle is ideally positioned at 75 degrees todeliver an efficient climbing position while also ensuring that therider’s hands and knees are comfortable during epic days. The front endof the bike is long to increase room in the cockpit and allow the riderto stretch out. The chainstay is modest at 427mm, blending stabilityand maneuverability. It’s long enough to give the bike optimum balanceacross its wheelbase but short enough to get out of your way when youneed to get the front end of the bike up. The back end of the bike isengineered for compliance and delivers a supple ride.

The Tyaughton features a 100% proprietary Knolly oversizedtube set with all frame tubes tapered, butted, bent and formed to thematerial’s limits. This allows Knolly to achieve subtle Knolly-esqueframe design emphasizing stability and compliance. This model alsofeatures a unique frame size specific tubeset to ensure riders of allsizes can get the maximum performance gain possible from this material.Large frames get the largest diameter tubeset to compliment largerstatured riders, while smaller frames get reduced diameter tube sets tomatch rider size and weight while providing matching compliance.

Inaddition, both Steel and Titanium frames have a unique head tube shapedesigned to maximize strength to support forks up to 170mm. Tubesetsflow into custom CNC machined dropouts, yokes and access ports(Titanium-only) so that stress risers are minimized. Even the includedISCG mount attaches cleanly into a recessed CNC machined pocket on thechainstay yoke.

Over the years we have realized that Knolly owners ride our products hard and often. This is great because that is exactly what we designed them for. Our goal from the beginning was to not only develop bikes that provide our loyal customers with an incredible riding experience, but to also provide solid support as well. Everyone here at Knolly is a rider so we take the engineering and manufacturing of our products very seriously, and we have partnered with one of the premier factories in the world to produce our bikes. We make some of the best product on the market and we are prepared to back that up by offering a Limited Lifetime Warranty* (to the original owner) on our frames along with an awesome crash replacement program.

What the frame warranty covers:
- Defects in materials and workmanship
- Bearings and fasteners for six months from time of purchase
- Rear shocks are covered by their respective manufacturer, typically for one year from the time of purchase

What the frame warranty does not cover:
- Normal wear and tear
- Damage to the finish of the frame from the application of frame protector coverings/sticker or     adhesive backed sheets
- Damage due to crashing and or abuse
- Damage from using non factory specified fasteners and bearings
- Damage from using non factory approved rear shocks
- Damage or failure due to poor, negligent or lack of maintenance
-  Damage due to improper installation of components
- Water damage to bearings, decals and finishes from high pressure washers and hoses
 - Dealer labour and costs for shipping warranty components to Knolly Bikes

What will void your frame warranty:
 - Modification of the frame in any way
 - Use of unapproved shock sizes for any chosen model

Our crash replacement policy is designed to support customers with frame failures that are not covered under our warranty policy. This mainly includes failures that are not a result of defective materials or workmanship (i.e. crashing). It does not cover frames damaged due to installation and use of components that are inappropriate for a particular frame's intended purpose, such as: using an 8 inch DH fork on a trail bike, etc.

We stand behind our products, and they are designed to last a very long time. Regardless of the reason that you need our assistance, whether it’s a warranty situation or a crash replacement situation, our goal is to get you back on the trails as soon as humanly possible. We take pride in providing great service, since we know that’s an important part of keeping you in the Knolly family for as long as you’re able to ride a bike.


"This bike hits above its travel, climbs as well as it descends and is comfortable in nearly any situation"

"The frame is impressively stiff for aluminum, without being harsh, and the suspension offers a near-perfect mix of traction, pedal-ability, ground hugginess and pop. It has the suppleness and capability of a long-travel bike, but it only actually has 135 millimeters—and is progressive enough to supply that telltale short-travel liveliness"

"Handling first, which is on the nimble side of the spectrum, even when the Fugitive is in its slackest position. While I wouldn't call it nervous, it's a bike that can change direction on a dime, a trait that makes it quite the machine in the slow to mid-speed jank that usually laughs at your efforts to hold any momentum. The blue bike can easily dart around those boulders and roots that need to be bypassed, and it's an easy thing to get off the ground when you need to go over them instead of around them."

"This is one hell of a fun bike in the corners, though, with a sort of energy that long-travel machines just can't match. It literally felt like it was jumping out of some of the tighter berms and bends, and it'll take only a handful of those moments before you realize what this whole short-travel movement is all about."

"A defining characteristic of Knolly’s suspension design is its near-legendary rear-end traction. It was clear immediately that this was a strength of the bike—seated or standing, the suspension clamped the rear wheel to the ground...."

"The complete lack of any noticeable climbing bob was impressive. I found myself looking down to check to see if the rear suspension was locked out because there wasn’t even any bounce even when fully open. With a steep effective seat tube angle, your weight is also centered nicely over the bike in a way that holds the front wheel down while also putting enough of your weight over the rear wheel."

" It may look like a heavy-duty rig, but the Fugitive LT offers a surprisingly nimble, playful ride. I started with the bike in its Neutral geo position, and its 66° head tube angle gave the bike snappy handling without feeling steep.The short rear stays also help the bike maintain a nimble, whippy character that makes attacking tight corners fun. Maybe I’m just getting used to 29ers, but I found the Fugitive LT more agile and easier to toss around than several previous niners I’ve ridden."

"When you start cranking hard, the Fugitive LT feels responsive to your efforts. While the rear end will move freely when a bump hits your wheel, it won’t let you wallow deep into the travel under pedalling forces alone"

Read the Full Review

"A capable climber and an enjoyable descender, the Fugitive LT is a bike that does everything—really well. In a world where everyone is trying to push the limits, Knolly has proven that more doesn’t always equal better. This is a bike for people who don’t want their suspension to numb the trail and find joy in the subtleties that make every descent unique."

Advanced geometry and a high level of construction with fully custom tubing throughout. its capable, simple,  durable and a whole lot of fun.


The feel of steel and it when its fully custom tuned by Knolly rather than off-the-shelf tubeset. Both steel and Ti Tyaughtons offer an exceptional ride quality - comfortable yet just enough snap to feel great under power.


The Tyaughton is made from air hardened steel, which is malleable and allows fine tuning of the tubing to Knolly's exact specs. It's heat treat to give strength and durability and also ED anti-corrosion coating to handle all-weather conditions.


Knolly skipped 148 Boost and went straight for 157TRAIL. Skipping the hype and focusing on where it matters - ride quality. Knolly's 157TRAIL gives us a stiffer 29" rear wheel, more tyre clearance, shorter stays and only a minimal effect on heel clearance at the chainstays


Tyaughton frames have unique head tubes that maximise strength in order to support forks up to 170mm in travel.


The Fourby4 has always been the core of Knolly's for that massive grip inducing traction in all types of trails. While the Tyaughton has no rear suspension or Fourby4, it's still hella fun, the steel or ti versions offer a nice damped ride quality which still searches for extra grip and the progressive geometry inspires confidence. Each frame gets a custom tubeset - the smaller sizes get tubes that are more compliant. The simplicity of a well designed hardtail made to ride the gnarliest terrain is a great feeling. No rear shock tuning or servicing so you can just get out in the mud an filth and shred your favourite trails and be liberated!

"The funness of a well thought out hardtail is hard to beat, you just get out and ride, explore and ride some more.  Climbing is quick and efficient and the progressive geo just oozes confidence no matter what trails you ride"


There is no doubt Knolly's are made to be ridden hard and being born on the shore means they need to be tough to take the abuse and aggressive riding they are built for.  A true test of the strength and durability is Knolly's Limited Lifetime Warranty. Knolly also offers an excellent crash replacement program

LOTS of details get poured into knolly's, not a detail is spared and it just feels nice to know your new rig is engineered from the ground-up.  with no new models being pumped out every year and a lifetime warranty - it's nice in this day and age to not have to replace your bike every year to get the latest and greatest.



SRAM's new DUB system comes in two versions. Regular and SB+. The regular version works on the Fugitive but you have to switch to a zero offset chainring (see below). The SB+ version has a bottom bracket, cranks and chainring combination that works perfectly on the Fugitive. The X01, GX, and Descendant 7k DUB SB+ cranks have a longer axle and a wider BB spacer that works with 157TRAIL. All the DUB BB's are the same.


A standard SRAM crank with a zero offset chainring - One-Up and Chromag both have a great option - will work but it does limit the largest ring size on the front to 32t.


Shimano offers their cranks with a +3 option (the part number should have a "B" on the end like this: FC-M8000-B). The axle length and BB are the same as their standard cranks so the offset is worked into the chainring mount. This system will work as both a 1x and a 2x option on the Fugitive. NOTE: this set up requires one spacer between the BB and the frame on the drive side. Maximum size chainring is a 32t ring with this setup. The XTR, XT and SLX cranks in this configuration work on the Fugitive. The new Shimano XTR, XT and SLX 12 speed cranks come in a 56.5 chainline


Any direct mount Raceface crank with a flipped Direct Mount ring will work. You can also run a direct mount flat ring from Black-Spire .Raceface rings come with a 3mm offset so when the ring is removed and flipped (the teeth profile works like this as well) it becomes a -3mm offset and the chainline works on the Fugitive. For a 1x system you can run a flipped ring on the Next SL, Next R, and Turbine cranks with a 134mm axle, or the Atlas and SIXC with the 136mm axle, or the Aeffect and Ride Cinch cranks with 137mm axle. For a 2x system you can run the Next SL, Next R or Turbine with a 143mm axle and a Boost spider. Helpful graphic for chainline. Raceface also now offers their cranks in a 143mm BB spindle which will provide a 55.5 chainline without having to flip the ring.


FSA has 5 different MTN cranks that work with our 157TRAIL rear. Their system is very simple - you simply move one spacer from between the crank and the spider to between the spider and the BB to provide the right chainline.


Mountain Biking is for everyone - Every size and every gender - Knolly has been making bikes for 16 years - bikes that get all riders out on the trails.

Because Knolly frames feature a continuous seat tube they allow for a full range of seat heights: on many other frames, the seat tube is either bent or interrupted by the shock allowing only a restricted range of seat heights (this problem is exasperated as frame sizes become smaller). Our frames feature both a continuous seat tube as well as a low “dropped seat height” - meaning the seat actually travels forward and out of the way - which allows riders of all sizes to get farther back on the bike when the terrain demands it.

One of the side benefits of Knolly's Fourby4 design is the ability to accommodate smaller riders, even with up to 170-200mm of rear suspension travel. This keeps the shock mounted low which means we can drop our top tubes for better stand-over clearance. It also means the center of mass on the frame is low and that equates to exceptional handling in technical terrain. Smaller riders can run a 150mm dropper post on our bikes due to the low stand-over height and straight seat tube.

Sizing these days is a hugely debatable topic - everyone is telling me to upsize, go for more reach. Much Confusion? You can feel confident knowing  that Knolly has thought through the details thoroughly and all their bikes offer a balanced ride and proper weight distribution for their intended purpose.

In an effort to help you find the right frame size we reached out to our Knation of riders and asked them these three questions: How tall are you? What is your inseam? What size Knolly do you ride?​The data below is from real riders, human beings that actually ride our product, so it is a great reference point to help you chose a frame size. Of course this is still just a guide but this is a great example for those riders that fall right in between sizes. Now you can see what other riders have chosen.
