Our third generation Living Link platform provides better power delivery, traction, sensitivity and support than ever before. Read More
Leaf Spring is partially flexed, adding support in the beginning of the sag range.
"With the new design, Spot managed to match the 130’s climbing ability, but on the descents, the 140 is a completely different, wild bone-crushing animal."
"The suppleness early in the stroke makes for confidence-inspiring control while tearing through roots at speed, and the supportive mid-stroke keeps the handling predictable when pressing into and accelerating out of the corners. Fun is my number-one gauge of a bike, and there is no shortage of good times when going downhill on the Mayhem 140."
"Spot is a family-owned company backed by loyal employes dedicated to designing great bikes. The brand doesn’t drop new models often, but when it does, you can bet the designers put their heart and soul into it. With the Mayhem 140, they’ve created something special."
"The Mayhem 140 brings a unique blend of traits to the table. It’s a fantastic climber, competent playful descender, and it’s equally fun on more mundane trails as it is on more challenging trails. Spot’s Living Link suspension delivers a lively, supportive, and composed ride that creates an engaging experience in a wide range of conditions.Colorado demands a lot of versatility from Trail bikes, it often asks them to act like Cross-Country bikes on long steep climbs, and then go downhill like Enduro bikes on insanely long descents. The Mayhem 140 taps into its Colorado heritage and does so without trying to be something it’s not — it doesn’t pretend to be a shorter travel Enduro sled or a beefed-up XC rig. Instead, the Mayhem 140 leans firmly into the Trail bike category and is better for it. There’s no identity crisis here— the Mayhem 140 is a Trail bike through and through."
"The Mayhem 140 is a brilliant all-around all-trail bike that’s fast, capable, and more efficient than most."
"It is a damn fine machine and has no problem matching up against the category’s elite."
"Thanks to that Spot energy, it climbs superbly and quickly for a bike in its category, with traction in spades and great support."
"Pushing myself down a descent with lots of speed variation, corners of all sizes and speeds, plenty of square-edged rocks (loose and embedded), and a handful of smaller drops and jumps, the Mayhem 140 was nearly magical. The wheels skipped and floated across the terrain while the bike above remained calm."
"Spot’s Mayhem 140 is quirky and a bit different. And it’s also one of the best trail bikes you can buy."
"My notes for the handful of rides I've taken it on so far all center around a similar theme that can be summed up in two words (that are best said with an East Coast accent): wicked fun."
"I ended up hitting some bigger moves on the Mayhem, ones that I typically reserve for longer travel bikes, largely because I wasn't worried about whether or not I'd end up blowing through the travel when I landed."
"The climbing position is upright and comfortable, and the suspension is efficient without being harsh, ideal traits for long rides on a variety of terrain."
"There's no shortage of good trail bikes out there these days, but Spot seem to have cooked up something a little different, a bike with suspension performance that helps it stand out from the crowd."
The Mayhem 140 is agile, and so are we. One of the many advantages of being a small, engineering-forward company is that we can react quickly to feedback. The original rubber protection that we designed for the Mayhem 140 went across the chainstay bridge and extended down into the wheel well. The thick rubber provided plenty of protection, but some taller tires were a tight fit. Based on feedback, we modified the protector to maximize tire clearance, offering more choice for riders. The new protector still runs across the chainstay bridge, but no longer extends down into the wheel well.
Tires that comply with the ETRTO standards for a 29x2.5-inch tire will fit with plenty of clearance. A running list of tires that are known to fit can be found here.
At the end of the day, it was a small change, but an important one for riders — and a perfect example of how nimble our passionate team can be in our quest to deliver the best riding experience possible.
Look at the drive side of the Mayhem 140 and you’ll see smooth, clean lines and minimal hardware. We went to great lengths making the 140 striking whether you’re feet or inches from it. All fasteners are accessed from the non-drive side, including the cable ports. Further increasing simplicity and reliability, the Mayhem 140 uses just 6 bearings, all of which are mounted into the links, not the frame members, and use replaceable secondary external seals to help keep moisture and contamination out
Pivots stay tight and quiet with our new SprockLock pivot system. Most hardware relies on friction to prevent loosening, while SprockLock provides a true mechanical interlock to prevent pivot hardware from backing out. A splined axle with a locking cap keys into the frame, creating a more failsafe system than expanding hardware, with simpler and fewer parts.
Cable Management: Nobody does cable ports cleaner than this. Rather than molding metal threads into carbon to cinch cable ports to, we came up with an elegant solution that reduces material and increases reliability. A single fastener ties both sides together, and threads directly into the drive side port/cover. Port covers are interchangeable to accommodate all common cable configurations.
While designing the Mayhem 140, we saw an opportunity to cut down on pesky frame rivnuts by developing a bottle mount that attaches through the Inversion link mounting bolts. The mount is also slotted to provide placement for a strap to hold a pump and spares. As an added level of convenience, the mount can be removed easily from the side of the bike. No need to fumble around the cage inside triangle. It might just be the coolest bottle mount ever made.
Anti-squat is a double-edged sword. It is the most important parameter to designing efficient suspension, but high levels in the wrong part of the travel will prevent the tire from tracking the terrain. By aligning the max anti-squat value in the travel range where the rider is pedaling, we minimize tradeoffs.
Compared with everything else on the graph, you can see that the Mayhem 140 follows a very different curve. Living Link Inversion gives us a level of control that other brands simply don’t have.
With Inversion we’re able to locate the highest anti-squat value directly in the sag range, where it’s welcome. Since the curve drops off dramatically at either end, we create a nice, soft stroke initiation and a much more active system farther into the travel range.
On the leverage rate side, the inverted leaf spring layout gives us added control as well. While most suspension systems provide a steady ramping of force through the stroke, Inversion lets us change direction midway through. At full extension, stroke initiation is easier due to a steep beginning curve. Transitioning into sag, the curve flattens and becomes very linear. This gives easier access to the deeper parts of the travel- something not possible with high levels of air spring progression. More performance, less harshness.
But the magic happens at around three quarters into the travel, where the leverage curve actually switches direction. Building bottom out resistance for the last portion of the stroke makes for a seamless, pillowy landing without compromising bump performance everywhere else. To top it off, all builds get a Rockshox Super Deluxe with Hydraulic Bottom Out control- trophy truck technology for your bike that puts clunky bottom outs in the past.
A nearly linear leverage rate behavior is excellent for bump absorption, but does not provide enough bottom out resistance. The Inversion system enables us to tailor the ends of the curve to improve bottom-out support while also increasing touch down sensitivity. The linkage arrangement of the suspension system creates a more progressive zone near bottom out. The flexure of the leaf spring acts as a negative spring at top out, helping with soft stroke initiation, and as a positive spring partway through the stroke, acting to straighten the curve in mid-travel. All of this combines to give a ride that delivers great traction when lightly loaded, a supportive, predictable mid-stroke response, and good bottom-out protection without having to tune excess air can progression into the shock.
The above graph shows the leverage rate curve of an imaginary Mayhem 140 without the leaf spring against the actual Mayhem 140. The leaf spring allows us to create a more linear center part of the curve, providing more usable travel in the mid-stroke while maintaining sensitivity at the top of the travel, and protection deep into it.
It’s taken me a handful of rides to adjust to my Mayhem 140 because it was a big upgrade for me, but I’m loving it. It’s smooth and stable, climbs great, and corners like it’s on rails.
I've had the new Mayhem 140 for a month or so and have put a few hundred miles on at my local trails. It's on another level from anything I've owned before, including the first gen Mayhem I had a few years back. It's fast gets to speed quickly and holds it really well. It rides/tracks great and feels so stable in all situations. To me there is a connected feel between the front and rear that I've not experienced before. I found myself being able to take bumpy lines I stayed away from before. Climbs, rides the chunky, loose terrain really well. Without trying I was setting PR times on most sections and had a bigger smile on my face too. The Blue looks amazing and photos don't do it just. Rockshox set up is the best I've ridded period and I've been a Fox Factory Kaskima coat guy for 7 years. Spot customer service was amazing and the way they box the bike up is F1 level efficiency. Crazy time in the bike industry right now and I'm confident I made the right purchase.
I purchased my 130 Mayhem in 2020 and felt it was a noticeable improvement over my previous Pivot 429. I absolutely loved it. Fast forward to April this year and I decided to upgrade again to the 140 and as much as I loved the 130, the 140 is even better. It climbs like a homesick Angel and descends like a banshee. I didn’t think the was much room for improvement on my 130 but well done Spot, you proved me wrong.

Only a few reviews so wanted to chime in after 70mi and 10 rides. Used on the wasatch bench, Huricane and Fruita. Previous bike was the Mayhem Gen 1 that I put 1800mi on with no issues. The 140 resolved the less than stellar uphill traction of the gen1. Ive cross shopped with demos on Esker Rowl, previous switchblade and latest Ripley and the 140 won out. I loved the Ripley on smooth easy jumpy trails but the low bottom bracket made it a nope for the rocky trails I do. Might get a similar feel with some carbon hoops on the 140. The previous swichblade was pretty similar to the gen1 mayhem. I love the performance of the 140. It is amazing on uphills, who needs a ebike? The downs are very good but I will say that the front wheel feels very in front of you due to a much slacker geo than the gen1 mayhem. This is great for confidence down steep rolers but does make it feel less precise on desert tech. I also find my medium waterbottle a pain to insert/remove even with side load cage. But thats all the negatives! The bike loves speed and wants to go up the steepest trails just to go back down them. I passed on a lot of amazing bike deals for the 140, yet I couldn’t be happier with my decision. This thing rips and feels like downhills both ways! Thanks Spot, keep listening to your customers and making amazing bikes.
In a word - yes. Allow me to expand.
I was able to demo the Mayhem 140 while in Golden just before the holidays. I was fortunate to be able to ride the new Virginia Canyon Mountain Bike Park. This is an amazing new trail system near Idaho Springs, CO. For now, at least, you have to earn your turns. Meaning that while there is amazing array of downhill features, you’ve got to climb from the base nearly 1,500’ to the top. Once there a rider has a series of progressive features as you weave your way back down.
The reason I point this out is that the ideal bike needs to be an efficient climber that can also rally when the pucker factor is dialed up. Candidly, most bikes are either good at climbing or good at descending - just not equally adept at both. The Mayhem 140 is a “unicorn”. This bike is astounding at both. According to Strava I earned PR’s both up and down - on my first ride on this bike!
The fact that this probably the most stunning bike I’ve seen in many years doesn’t hurt either.
Finally, allow me to address an issue that has been bandied about - tire clearance. This is a NON ISSUE. Based upon a rather dubious review I had read in the days leading up to this demo, I was concerned that the clearance between the rear tire and the chain stay would be too tight. The “problem” was the result of a rubber guide that extended around the chainstay/tire interface that competed for the space. A great idea considering the potential for tires to pick up…
