Introducing the 2015 Pivot Mach 4 Carbon
With so many great bikes on the market, striving to remain competitive is as fierce in the design room as it is on the race track. Towards that end, Pivot went back to the drawing board and have emerged with a model that introduces the next generation of race/trail geometry packed into its lightest (2.3 kg / 5.1 lbs) full suspension frame they had yet to produce! As Pivot designer Chris Cocalis put it, the “Mach 4 is really the bike that started it all for Pivot” so revamping the model in its 4th generation was a huge gamble.
They started with the notion, a core requirement rather, that it needed to perform well on and off the XC course in a wide variety of terrain. Working from the ground up, they designed it around 27.5 wheels and played with a variety of travel ranges until they found a sweet spot at 115mm. With these pillars in place, the bet pays off and the bike maintains its known pedaling efficiency while taking its trail performance to the next level. But this was only the beginning.
Working directly with Fox, they developed a custom tuned Fox Float CTD Kashima rear shock that has a dual position sag indicator. This allows the rider to set up the rear travel for either trail or XC. In the race mode, the geometry and suspension feel retains its predecessor’s climbing and acceleration performance, while the trail setting gives the bike a much more plush experience.
The product team was keen on retaining the agility of the 26-inch wheel while benefiting from the rollover ability of a slightly larger wheel. But coupled with its dw-link suspension system, stiff carbon chassis, and short chain stays; the bike climbs like a mountain lion.
A cool new feature on the Mach 4 is their cable routing system. This includes interchangeable cable ports for a variety of routing options and is fully compatible with a dropper seat post. This includes full length cable housing and options for Shimano’s new M9000 Side Swing front derailleur.
The Mach 4 Carbon is also the first frame ever developed that is fully compatible with the Shimano XTR Di2. This includes an internal battery mount in the down tube and all the required ports for clean internal routing.
Pivot continues to cater to the smaller rider by offering the frame size starting with extra small and up through large. The XS has its own geometry and suspension including the lowest stand-over clearance of any 27.5 full suspension bike on the market.
The rubberized leather downtube and swingarm protection is cool new feature that keeps cabling clean and protects the bike. When fully equipped, the bike weighs from 10kg / 22 lbs.
Now, getting to brass tax, technology does come at a price. While estimates for the complete set up are still being crunched, the Mach 4 Carbon frame and shock will cost around £2400 GBP.
Seeing is believing, though, so check out this demo video to help ease the sticker shock.
