It's like the Fugitive on Stanazolol - and if you've ever ridden a Fugitive, you know that thing punches way above its weight.  WIth up to 167mm in rear travel 63.8º head angle and compatible with 170mm (and even dual crown) travel front fork, you can only imagine the damage you could do with this thing.

After the Warden, everyone has asked for a long travel 29er - some just like that extra bit of error-correction when riding gnarly trails, some like to launch of un-imaginable drops and some are psychos.  Welcome to the new Chilcotin.
A 63.8º head angle and 466mm reach on the medium is not insanely long like others, but in true Knolly fashion the geometry piques the balance of stability and ground hugging nimbleness.

We don't need to tell you how good the patented Fourby4 suspension is - every single review has done that for you. What we can tell you is that this beast is going to claw up the trickiest climbs and let you open it up on the descents. Smash, carve and boost with precision. It's suited to bike bike park, DH runs and freeride hits all day - and it's backed by Knolly's lifetime warranty. If you are an aggressive rider and know how to throw a bike around the Chilcotin will be your best friend, it will crush DH trails under the right rider.

That funky seat-tube bottom bracket junction might look strange but it's for your benefit. It gives an uninterrupted seat tube, so you can run the longest dropper without bumping into pivots or kinks in the seat tube. It also clears up a ton of space at the bottom bracket area so you can fit massive tyres and keep those chainstays short. Getting your dropper post low is not a trend, it gets your your center of gravity as low as possible giving that racecar like cornering in "in-the-bike" feel.

Just like the Fugitive and Warden, the Chilcotin uses the 157mm rear spacing - Knolly's implementation is just so good why wouldn't you? Wider spaced rear wheels are way stiffer than 148mm spacing and it hardly effects heel clearance.  Hub and rim choices are now pretty easy to find if you are looking at building up a frame.

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.


"The Chilcotin is an efficient pedaler, and it’s only helped by its 29” wheels. I climbed a proper singletrack trail with the rear shock wide open and never felt like flipping the switch to stiffen it up. Knolly’s bikes do a great job of keeping your rear wheel stuck to the trail, and with the shock left open you’ll get a ride that’s supportive to pedaling efforts but very forgiving to trail inputs."

"The new Chilcotin’s slacked-out steering is great; after riding a few beastly enduro 29er’s recently, I’ve come to find there is little sacrifice in either their generous suspension travel or downhill-friendly head tube angles. I have no issues climbing through tight switchbacks with a slack, long wheelbase bike like the Chilcotin, and that kind of geo makes descending tons of fun"

The Chilcotin represents thelongest-travel of Knolly’s offering, and carries forth the brand’scalling cards like highly engineered design, use of quality materials,extreme attention to detail and high-end manufacturing.

"The Fourby4 suspension provided anefficient platform that felt supportive enough for one tester to climbwithout the added firmness of the shock’s extra pedaling platform, andto favor it over the Trek Slash, an equally burly bike. "

"The Chilcotin felt as planted as alate-summer garden on the middle section of our test trail, whichconsisted of a wide-open, washed-out, scree-filled doubletrack thatbegged for (puckered) reckless speeds. Even at 30-plus miles-per-hour,the ride was extremely stable and afforded great confidence aroundsweeping, loose corners. When the trail narrowed and turned moretechnical, with a mess of ledgy drops and straight-line chutes, theChilcotin was equally as plank-like. It felt balanced front-to-rear, andthe suspension nailed all the buzzwords: supple off the top, supportivein the middle and resistant to bottoming out. "

"It is a brawler, meant for the rowdiest of rides and the most capable of bike handlers. "

The Chilcotin’s geometry is highly progressive but not designed to escalate or play one upmanship with the “longer, lower, slacker” trend. Most bikes in the industry are built (and sold) on their static geometry, which is not indicative of how they actually perform on the trail. We have always focused on the bike’s “dynamic geometry”: how the bike performs when it’s actually being ridden aggressively, not how it looks on paper.

“Dynamic geometry” is a combination of the frame’s physical dimensions superimposed on the frame’s suspension performance. Travel and geometry numbers only give part of the picture as rear suspension performance matters and nothing beats our Fourby4 in sophisticated trail smashing performance. The Chilcotin monster trucks at speed, yet remains nimble and predictable in all situations.

The Chilcotin features a steep 77.8 degree effective seat tube angle so that you can pedal to the top comfortably and a 63.75 degree head tube angle (slack mode) to give you a longer reach. There are two adjustable geo settings (slack or neutral), so that you can tailor your set up to match your riding style. It’s as simple as removing a bolt, sliding the shock forward or back and re-installing the bolt.

Loosen one bolt and move the lower eyelet to your preferred setting. No more flapping around with chips, flips and extra pieces of sh*t that you'll most likely lose on the trail. The "Slack" position slackens the head angle and bottom bracket while increasing the progressivity of the suspension - perfect for DH shuttle runs or park days.


When it comes to details, Knolly sweats them. The internal routing is so easy to use - the large port at the downtube makes it easier to feed cables through. The entry ports feature Knolly's own cable ports which put tension on the housing to keep everything nice and quiet.  Listen carefully and you can hear the rubber on your tyres wearing down.


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 1.5mm of heel clearance added to each side and a noticeable difference in bike performance.


The Fourby4 suspension platform is the cornerstone of Knolly Bikes. Inspired by Formula One auto racing strut-style suspension, Knolly’s patented Fourby4 suspension technology provides freedom in design and execution that no other design in the industry can tout. This freedom means that Knolly can design each model from the ground up and manipulate wheel path and shock progression completely independently. This allows each model to have suspension rate curves that are generally linear to progressive, which is important because it means your shock doesn’t have to ‘save the day’ by providing lots of bottoming resistance, as it would on a bike with a falling rate curve. This helps keep your shock from being over-worked and over-heating on long downhills, which can affect shock performance. This also helps maintain normal shock service intervals. Each of our bikes have rate curves and leverage ratios that are implemented for a certain type of riding(trail, AM, DH)

"So Knolly’s unique and multi-patented Fourby4 Suspension is quite simply the most advanced and highest performing suspension design used in the mountain bike industry."

What's it like to ride

If you have never ridden a Knolly, we do ask to get in touch with us for a demo ride. The feeling cannot be fully described in words.  The magic happens with the patented Fourby4 suspension. First off you'll notice lots of sensitivity to small bumps, this also translates to climbing technical terrain - on most bikes you'll get a scratchy feeling when clawing up steep rocky pitches and the need to constantly keep weight on the rear to keep it biting - This trait is common with bikes with a lot of anti-squat  as chain tension wants to extend the suspension - this feels great on fire road and tarmac climbs, but we are not here to blast up fire road climbs!  With the Fourby4 you'll notice it sticking down to the terrain and the more power you can put out the rear just keeps on digging in. Imagine this on technicnal, slippery rooty and rocky terrain - it feels brilliant. By having independent control with the wheel path and and shock progression allows to fine tune the ride depending on the style of bike and not being reliant on the shock "saving the day" with bottom out resistance.
Knolly sums up their traction in Fourby4 "This is priority number one. Without traction, there is no confidence… without confidence, there is no fun. "


151mm or 167mm

167mm or 151mm travel options

The way you want it.

The Chilcotin platform is incredibly versatile with one frame and two suspension travel options. This offering allows our riders to set up their bikes based on their riding styles. The Chilcotin 151 build kit features a 160mm fork and 151mm of rear travel. The Chilcotin 167 build kit moves to an aggressive chassis 170mm fork (38 Float or Zeb) and increases rear travel to a fully progressive 167mm for extra back cushion when you need to push your riding to the next level. The Chilcotin also has two lower shock mounts for altering the travel option.


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

Arguable one of the finest aluminium bikes on the market. NOT A DETAIL SPARED - Hassle free internal cable routing, dual-row Angular contact bearings, custom machined titanium axles and the CNC mitered tubeset for gap Free weld junctions. all backed by a lifetime warranty




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.


FOURBY4 Suspension is designed to suit air and coil shocks - and they will both work exceptionally well.  The 160mm Warden uses a TR205 x 60mm length shock and the 168mm (LT) uses a TR205 x 62.5mm. Same frame just a different shock stroke. Frameset + Shock options available and complete factory bikes - Start building your bike today.


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.
