The Mayhem is again, and Spot calls it essentially the most superior bike they’ve ever made. Whereas nonetheless counting on a titanium leaf spring like their Dwelling Hyperlink platform has earlier than, the orientation has been flipped which Spot calls Inversion or the third technology of the tech. There’s additionally a brand new Slaybar body design with a number of intelligent options making the Mayhem one to take a look at.
Spot wished to create a motorcycle that was lighter, stronger, and one which each climbed and descended higher. No small order. Nonetheless, they really feel like they crushed all their targets with the strongest body they’ve ever examined, whereas additionally lowering the quantity of components.
Stating that they reached the restrict of what they may do with the present leaf spring association, the brand new structure flips the leaf spring and essential pivot which ends up in a lot of enhancements:
Improved pedaling effectivity with extra grip
Extra usable journey by making the mid-stroke leverage fee extra linear
Higher bottom-out management
Higher small-bump compliance
Softer touch-down really feel
Focuses anti-squat extra in sag vary
The patented system makes use of fewer components and simply six bearings. It additionally introduces a brand new suspension curve that features particular person phases for landing, sag, vary, and bottom-out management. As Spot explains, “a shallow, straight, progressive habits is great for bump absorption, however doesn’t present sufficient bottom-out resistance. The Inversion system allows us to tailor the ends of the curve to enhance bottom-out assist whereas additionally growing touch-down sensitivity. The linkage association of the suspension system creates a extra progressive zone close to backside out. The flexure of the leaf spring acts as a detrimental spring at high out, serving to with mushy stroke initiation, and as a optimistic spring partway via the stroke, performing to straighten the curve in mid-travel.
All of this combines to provide a journey that delivers nice traction when frivolously loaded, a supportive, predictable mid-stroke response, and good bottom-out safety with out having to tune extra air can development into the shock.”
Transferring on to the body design itself, their new ‘Slaybar’ design basically subdivides the primary triangle into two smaller triangles for elevated assist of the shock and body forces. Spot admits they’re not the primary so as to add an asymmetrical body assist, however not like one thing just like the Specialised Sidearm, Spot’s assist divides the primary body into two triangles, fairly than a trapezoid.
They declare this reduces stress on all components of the body together with the bearings to allow them to use much less materials and create a lighter, decrease upkeep body. In consequence, the Mayhem 140 is 10% lighter than the outgoing Mayhem 130, whereas 56% stronger than the Mayhem 150!
Extra particulars embody their SprockLock system on the primary pivots which use a mechanical lock to stop the {hardware} from having the ability to again out. By avoiding collet-type {hardware}, they’ll keep away from having to make use of aluminum components molded into the carbon to withstand radial growth, and might make it lighter and stronger.
Because of the new location of the Dwelling Hyperlink in entrance of the seat tube, Spot noticed a chance to chop out the rivnuts within the body for a water bottle cage and as a substitute mount it on to the leaf spring mounting bolts. There’s additionally a slot to make use of as a strap anchor to hold spares in case you’d fairly try this as a substitute. You’ll additionally discover a threaded backside bracket with ISCG 05 mounting tabs.
Even the cable port has been scrutinized with a intelligent thread-together system that stops them from having to mould steel threads into the carbon. Whereas the cable routing is inner, the threaded system seems to lock the cables in place to stop rattling.
Constructed round 29″ wheels, the Mayhem 140 contains 140mm of rear journey and a 150mm journey fork (160mm journey elective). Frames can be found in Liquid Black or Alpine Blue, and pricing begins at $3,799 for the frame-only, or $5,999 for a 4-Star construct with SRAM GX Eagle. It’s obtainable for pre-order just for now, with bikes delivery in September.
