The Pivot Mach 4 is not only designed for smaller riders, but it is also ideal for riders who need more space to move while they ride. The 5. 1lb frame is Pivot's lightest, yet it doesn't compromise stiffness. It sticks a track just as well as Pivot's XC bikes with the plush ride of a full suspension. The rear suspension is provided by the DW-link design with 115mm of travel. The link system is designed to provide enough travel for the gnarliest of trails while ensuring that all of your pedal power propels you forward. It is paired with the FOX FLOAT CTD Kashima shock, which is tuned to use every bit of movement available, so even with the 115mm of travel, your ride will feel bigger. To complete the frame, internal cable routing is part of the design. The geometry has been tweaked to work with either a 100mm or 120mm fork. And while the shorter travel means more speed, the 120mm will give you a ride with a bit more slack.
