Low-slung & gung ho for XC and trail dominance.

Look at that swooping top tube. Just look at it. It captivates the eye like a surrealist painting. But the Pivot Mach 4 Carbon isn’t overly concerned with making an aesthetic statement. That top tube yields the lowest standover clearance you’ll find on a 27.5in-wheel bike, making it a bike that accommodates smaller riders with ease and excites active riders of all sizes. What do we mean by active? In today’s world of auto-piloting steeds, there are still those who prefer to own the space above the wheels without unnecessary intrusion from their equipment, being free to burst, shift, and lean their way with precise and calculated movements over the trail’s obstacles. If you consider yourself an artist in motion, the Mach 4 Carbon may be your new preferred brush.

The podium-hungry Mach 4 Carbon is, simply put, the lightest full-suspension bike Pivot has ever made (5.1lbs min). But if you’ve ridden one of Pivot’s recent carbon offerings, you know the company’s standpoint on carbon design — stiffness comes first. Even Pivot’s XC bikes track over rough terrain with unwavering accuracy. Hard corners, off-camber landings — if you feel some flex from the Mach 4 Carbon, it’s almost guaranteed to be coming from the wheels and tires, and that gives you ample control to ride at the edge of sanity.

Suspension duties for the Mach 4 Carbon are handled by the proven DW-link design, which yields 115mm of smooth travel while counteracting speed-robbing pedaling forces. This translates to race-worthy acceleration and consistent contact with the trail. Stand up and stomp on the pedals and you’ll be amazed at the grip you get on loose dirt. Because Pivot worked closely with FOX on the FLOAT CTD Kashima shock tune, your suspension and shock will combine to provide travel that’s responsive, predictable, and uses every available millimeter. As with prior iterations of the legendary Mach 4, you’ll feel like you’re riding a bike with more travel.

To keep everything tidy and quiet, the Mach 4 carbon comes with full-length internal cable routing, including internal routing for a dropper post. This frame can be paired with a 100mm fork for pure XC speed, but it’s also at home with a 120mm fork for increased confidence on rough trails. The longer fork will slacken the ride a bit, but with DW-link suspension in back, the Mach 4 Carbon rides high in its travel, so you won’t experience any front-end wandering.

awesome XC bike

    I had a chance to demo this bike several times in Moab,UT at Outerbike and I really loved the ride quality. This is Pivots lightest frame ever,5.1 lbs in a medium. Even though the bike is extremely lightweight it never felt flexy on the trail making for a very stable platform to crank on. With a relatively short wheel base and a fairly slack head tube angle-68.2 with the 120mm fork i felt it opened up the bike a bit allowing for quick,flick-able turns on the trail and super fast bombing descents. In other words you are not pigeon holed into an XC bike as it is well suited for all mountain terrain too. To sum it up this bike is a very versatile, well rounded steed that's very light weight and responsive on the trail. It definitely left me with a smile on my face and I am 100% sure you will have the same reaction.

    Sweet Bike

    • Familiarity: I've put it through the wringer

    I am a young female athlete that loves to compete in XC Racing. I have made the move from a 29er hardtail of a different brand to the Pivot Mach 4. From the first ride the bike felt amazing, the fame felt pretty stiff on the climbs but i was able to go a lot faster on the DH.
    I got a small since i am 5'4"-ish. I have to run my seat pretty slammed forward on my seatpost, it looks funny but it does not feel funny at all.
    I have it set up with a 100mm fork since i use it for XC Racing.
    Overall it is a pretty light frame/fork build for a full suspension bike!

    Great bike, highly versatile

    • Familiarity: I've used it several times

    So I spent a weekend (probably about 6 hours total ridetime) on a Mach 4 carbon. This is a 115mm rear travel bike with a DW-link suspension, and the short story is: this thing rips!



    Long story - I love the suspension design on this bike. Between the efficient translation of pedaling power and the nimble lightweight wheels, it accelerates SO FAST out of corners and turns. Getting up to speed takes hardly any effort at all. I love this sort of spirit in a bike, because it makes it just so fun and playful on a trail. Always eager to charge!



    Adding to the playfulness, the head-angle is relatively slack for a shorter travel bike, which let me comfortably charge downhills in Phoenix (Mormon/National) that are really pretty gnarly. The short chain stays also mean it is ready to wheelie and manual and reposition without effort.



    Probably the coolest thing about this bike is the versatility. With a straight carbon post, some light weight carbon wheels, and a 32mm fork and XC tires - you could race XC and stage races on this thing, no sweat. Buuuuuut if that's not your bag, then you could put a 130 or 140mm travel-reduced Pike on there, some fat rims like the Ibis 741s, and some knobby tires and suddenly you'd have an incredibly playful trail bike that could shred some downhill, but still happily get you up the climbs. That's a knockout versatility in a bike that is hard to find in a lot of rides.



    A bike that can switch between XC racer one day and a downhill-charging trail bike the next is worth its weight in gold.



    Adam DeWitt helped set up this weekend experience for me, and is a great guy in general who you'd love to share a beer with on the trail. If you wanna buy a bike - or anything else from backcountry - give him a ring! Extension 5630. Thanks again for helping make this happen, Adam.

    Unfortunately Adam is no longer with the company but any of our sales guys can help.
