Mayhem 140

• You say the Mayhem 140 is more capable than the previous Mayhem 150. How is that possible if it has less travel?

  It really comes down to several things working together to make an overall higher performing bike. Our third-generation Living Link suspension platform plays a big part, because it provides more millimeters of usable travel, a softer touch-down feel, improved traction and better pedaling support.

• What type of riding is the Mayhem 140 designed for?

  The Mayhem 140 is at home on an exceptionally wide range of riding.

• What is the recommended sag?

  We recommend between 28 and 32 percent, to suit rider taste and terrain.

• Should I climb with the shock locked-out?

  Don't touch that dial! All our full suspension bikes are engineered with exceptional pedaling efficiency with the shock open, thanks to our patented Living Link suspension system.

• Will a RockShox Vivid Air or Fox Float X2 fit on the Mayhem 140?

  Yep, and it'll increase the bike's bump eating appetite with very little sacrifice to pedaling efficiency. We recommend a low compression, medium rebound tune.

• Can I run a coil shock on the Mayhem 140?

  Go for it. The leaf spring in our Living Link system acts as a positive spring partway through the travel, helping with mid-stroke support and supplying bottom-out protection. Additionally, we kept the rear eyelet hardware narrow specifically to allow spring changes without removing the reducers.

• What size shock does the Mayhem 140 run?

  230x60mm | Reducers: F: 10x30mm R: 8x20

• How much does the frame weigh?

  Depending on size and color, the Mayhem 140 frame weighs between 6.8 and 7.2lbs (3,087-3,270g) with the stock Rockshox Super Deluxe shock installed.

• What fork travel can I run?

  The Mayhem 140 is designed to run 150mm or 160mm up front. Default build spec is 150mm, but since every bike is built to order, going to 160mm is as easy as asking.

• What size tires fit on the Mayhem 140?

  We designed the Mayhem 140 to clear 29x2.5-inch tires.

• Can I run a mixed-wheel setup?

  Using a 27.5” rear wheel will lower the bottom bracket and slacken the seat tube a very undesirable amount. While a small wheel technically will fit, the bike was not designed to be run this way and we don't recommend trying it.

• Does it have a UDH?

  The Mayhem 140 does accept a UDH, meaning it is compatible with SRAM Full Mount derailleurs. Complete bikes spec'd with Full Mount derailleurs will not come with the UDH itself since it is not needed. Frame-only purchases will ship with a UDH installed.

• What are the minimum and maximum rotor sizes?

  Without any adapters, you can run a 160mm rear rotor and the frame will clear up to 200mm.

• What seat post diameter does the Mayhem 140 take?

  31.6mm. This diameter is used on every mountain and gravel bike in our lineup.

• What size are the pivot bearings?

  We use just 6 bearings in total, and they're all the same size: 3802. Use only dual-row, full-complement bearings like Enduro™’s MAX series.

• Why is the brake mount a separate part and not molded in to the carbon like most frames?

  It improves caliper alignment, makes caliper position adjustments easier, transfers braking forces more directly into the frame, and reduces the number of threaded holes in the frame.

• What style of headset does it take?

  Top: ZS44 | Bottom: ZS56

• What style bottom bracket shell does it have?

  73mm Threaded, also referred to as BSA.

• What type of cranks can I run?

  Anything with a direct mount single chainring that provides at least a 55mm chainline.

• What size chainring can I run?

  We spec the Mayhem 140 with a 32-tooth ring because the suspension kinematics are optimized around that size. The bike can be ridden with a 30-34t round chainring, or up to a 32t oval chainring. Deviating from the stock 32-tooth ring will change the suspension characteristics slightly when pedaling.

• What's the rear axle spacing?

  12x148mm, also referred to as Boost. All of our current mountain bikes use this rear axle spacing.

• How do I run the cables?

  For assembly instructions, check out the Mayhem 140 manual.

• What is the Frame Warranty?

  Lifetime on manufacturing defects for the original owner, and a generous crash replacement policy.

• What is the ASTM classification of the Mayhem 140?

  Category 4: All-Mountain and Enduro riding.
