Mayhem 140
Just rode Virginia Canyon and it was one of the most fun rides I’ve ever had. There’s not many trails in this state that this bike can’t handle.

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.
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.
Just rode Virginia Canyon and it was one of the most fun rides I’ve ever had. There’s not many trails in this state that this bike can’t handle.
The folks down at Spot have really outdone themselves this time. What an incredible ride! I have had Spots before and have always believed they were the best of the best, but my gosh, this is next level. I have been riding this bike now for about a month and am consistently hitting PR's on all sorts of different terrain. The stability gives great confidence on the descents and the newest iteration of the living link keeps your wheel glued to the ground in gnarliest of climbs. There is a sensation of almost being lifted over the hard bits. I am so incredibly impressed. This bike is indeed the one bike quiver killer!
This is my fourth SPOT bike and, easily the best! Super fun bike to ride, surprisingly, a better climbing bike than anticipated and amazing descending abilities. I HIGHLY RECOMMEND....SOLID!!
Took the M140 (5*) out for a demo from Spot's HQ on a nearby trail system (Apex). My current two primary rides are a Ryve 115 and Mayhem 150. From a comparison standpoint, the 140 is the best of both worlds and then some. The climbing efficiency is very similar to the Ryve (plus a couple pounds) while it descends better than the 150. Super stable/planted yet playful and floaty. Blasts through chunk like it has more travel than advertised. I've owned/demoed a lot of bikes over the past two decades and this is hands down the best bike I've ridden. I tend to follow the N+1 rule when it comes to mountain bikes, but the 140 may cause me to shift my quiver to N=1.
The SPOT Mayhem 140 is truly a WOW bike. Lots a stable travel, feels planted on the trail but climbs well and feels very lively and quick. Super Fun!
