The leverage exerted by the Defcon mp4 suspension is progressive. There are multiple benefits to a more progressive suspension system. The rear shock can be tuned more linearly for a smoother, more plush ride without bottoming. Because the rear shock can be pumped to lower air pressures without performance detriment, shock and seal life are optimized and a greater range of adjustability is available.

The custom one-piece bell crank on the Defcon increases frame stiffness while allowing for the elimination of a seat stay bridge. The absence of a seat stay bridge provides more tire and suspension clearance while creating shorter chain stays and seat stays for even greater stiffness and better handling.


The custom frame tubes on the Defcon are made by SPF Air Forming. SPF is carried out at high air temperatures, where the tube structure is in its most ‘plastic’ and formable state. This allows more complicated shapes to be produced that cannot be made using traditional forming techniques. For example, whereas shape designs can be applied to 25% of the tube using hydroforming, SPF allows up to 90% manipulation. The result: more optimized shapes and less weight.


USA made Enduro® Max sealed bearings sustain 40% more load capacity than standard radial bearings & provide more lateral support for the multiple forces associated with mountain bike pivots. MAX bearings use CRC Marine Grease that will not wash out or breakdown under extreme circumstances.


Our 10mm shock hardware is NOT the standard from our rear shock suppliers. We have to pay more for it and our production lead times are usually increased because we specify it. But the increase in lateral and torsional stiffness for our frames and the rear shock durability and performance is worth every extra dollar and every extra delivery day.


15mm thru-axle QR’s offer all the benefits of the 20mm thru-axle design (stiffness!) + the benefits of the standard 9mm QR system (quick wheel removal!) without any of the down sides. The weight of the 15mm system is similar to the classic 9mm system (thanks to the lightweight alloy axle & reduction in fork leg weight) , but it is nearly as stiff as a 20mm axle. The increase in stiffness improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance.
