At this year’s Sea Otter Classic, Pivot Cycles brought a new prototype bike called the M4X. Designed for 4x/dual slalom duties, this little shredder is quite the eye catching bike. Check out the details on Kyle Strait’s Prototype M4x.

Based off of the Pivot Mach 4, the M4x takes it up a notch. They incorporated a stout aluminum CNC lower pivot and it has CNC’ed ISCG-05 chain guide mounts integrated into the bottom bracket.

The frame gets 100mm of rear wheel dw-link travel and the upper pivot is carbon fiber.

Pivot uses a shorter rear end with a thick aluminum derailleur hanger in the back.

This bike is still a prototype but it seems like a few people are anxious to see if this prototype makes it into production. Kyle chose to ride his M4X at both the Sea Otter dual slalom as well as the downhill. Up front, the m4x uses a tapered head tube.
