On descents, the most capable machine isn't going to be the most capable on the way up. Yet, with each passing year, those lines are constantly blurred by bikes like the Pivot Mach 5.7 Carbon. With a chassis that's a half pound lighter than its alloy stable mate, proven DW-Link suspension squeezing out 145mm of travel, and a XT/XTR PRO Complete Mountain Bike kit, this Pivot's destined to make the climb as rewarding as the descent.

By taking advantage of the latest molding technology, Pivot knocked the Mach 5.7's frame weight down to around five pounds (with the rear shock). This included using sacrificial internal molds to provide increased compaction of the laminate and to create a smoother inner-surface. This has resulted in a stronger and lighter bike without the wrinkles and excess resin that plague intricate monocoque layups.

At the rear triangle, instead of two struts connecting the seat and chainstays, there's just one on the left side. And there isn't a seatstay bridge either. These changes help to increase the mud clearance over the alloy Mach 5.7 frame. Up front, it gets the same tapered head tube that allows Pivot designers to shape a massive down tube for steering stiffness.

There are a few other details that emphasize the efforts towards optimizing frame stiffness. One of the easiest to see is the BB92 PressFit bottom bracket. The extra width in the shell does two things. First, it allowed frame designers to connect a massive down tube and increase the width of the lower DW-Link, which boosted stiffness and resistance to torsional flex. Secondly, it provides better support for the bottom bracket bearings. And speaking of bearings, the forged and CNC-machined aluminum lower-link contains eight sealed cartridge bearings — two at each corner. This increases the durability of this pillar component, it stretches service life, and it optimizes suspension function. The upper-link is made of carbon fiber for both strength and light weight, and since it sees less stress than its lower counterpart, Pivot relies on four bearings — rather than eight like the lower-link — to keep the suspension operating smoothly.

Out on the trail, the Mach 5.7 Carbon remains firm while hammering out of the saddle, yet it glides over rocks, roots, and ruts. It's possible to have both firm, efficient pedaling and bump compliance because of the DW-Link suspension's natural anti-squat characteristics. When you're on your bike, the center of mass is somewhere near your belly button. And every time that you accelerate, this mass shifts rearward, loading the rear suspension. DW-Link counteracts this transfer in order to minimize bio-impact on the rear suspension.

With the DW-Link design controlling unwanted squat, a lightly damped shock is able to respond with extreme sensitivity to the demands of the trail. In this case, FOX's FLOAT CTD with Kashima provides the motion control. Leading the Mach 5.7 Carbon down the trail is a 150mm travel FOX 34 FLOAT FIT CTD For with Kashima as well. This gives the 5.7 a 67.6 degree head angle, keeping it stable at speed.

The Mach 5.7 rides on wheels consisting of DT Swiss 350 hubs and Tricon rims with a Kenda Nevegal up front and a Honey Badger tire in the rear. Shimano XT occupies the crankset (24/38t), cassette (11-36t), shifters, and front derailleur. An XTR rear derailleur makes sure that shifting is as crisp and fast as possible, while XT brakes and 180mm front and 160mm rotors scrub speed with minimal effort.

Finishing the build is a FSA SL-K seatpost, a WTB Vigo Race saddle, a FSA SL-K stem, and a 740mm-wide Phoenix carbon riser.

The Pivot Mach 5.7 Carbon XT/XTR PRO Complete Mountain Bike is available in the colors Matte Black/red, Matte Black/green, and Matte Black/blue and in five sizes from X-Small to X-Large.

How I love Thee, Let me Count the Ways

  • Familiarity: I've used it several times

Not buying into the whole 27.5" wheel marketing scheme sweeping through the industry, I spent months trying to hunt down the perfect all mountain 26" wheeled bike that would fit my small build (i'm 5.3"), would kill it downhill, and would climb like a light weight xc bike. Needless to say, this was not an easy task considering most bikes were too large, and most companies aren't making 26" frames anymore. Other bikes I had considered: Ibis SL-R, Ibis HD, and Yeti SB66. Then I discovered the Pivot Mach 5.7c, which came in an XS size!


After deciding to pull the trigger in buying a bike that was worth more than my car, I said "screw it" and placed the order. Needless to say, I have ZERO regrets. Since the bike has arrived, I've squeezed in about 10 rides on it and it has simply just blown my mind each time. The bike is stiff as hell, climbs like a freakin' rocket, and is wicked fun going down hill. I ended up getting the full XT build, put on some I9 wheels, and have the KS Lev 125 drop seat making this my dream bike. Simply put, if I could marry this bike, I would.

If you are looking for a super plush all mountain bike that acts like a long legged XC bike on the ascents and an enduro bike on the descents, you MUST give this a ride. You may just fall in love.

Very Capabale, fast, DW link is stiff

  • Familiarity: I've put it through the wringer

I have the Aluminum Mach 5.7. Have ridden it for the last 18 months with full XT/XTR setup and Fox Talus 150. Great bike, could be a little more plush but really eats the uphill sections for the amount of travel it has. Rode Gosseberry with it and had a lot of fun there.
