Pivot Mach 5.5 Carbon Pro X01 Eagle Reynolds Complete Mountain Bike - 2018 $8,399.00
Conquer anything on the trail.
Building on the legacy of Pivot's iconic Mach 5.7 Carbon, the Mach 5.5 Carbon Pro X01 Eagle Reynolds Complete Mountain Bike pushes the design envelope with progressive geometry that's longer, slacker, and lower than ever. It handles everything the trail throws your way, from chunky, rock-littered climbs to blistering descents with square-edge hits, sudden drops, and rock rolls just begging for action. Pivot places it firmly into the trail category, with a secondary focus on all-mountain exploration. To be blunt, we just call it "damn capable" and "stupid fun," making it a worthy rig for the aggressive rider demanding their bike to climb like a goat and descend with unflappable composure.
The Mach 5.5 Carbon retains the sought-after benefits of the DW-Link suspension platform, namely the ability to claw up the steepest, chunkiest climbs and soak up square-edge hits on the descent. Once you've reached the summit after a grueling climb, 5.5 inches of rear travel gobbles up loose rocks and smooths out square-edges at high speeds. It's all party up front, with 6 inches of travel providing the confidence to rally across anything in sight, including sections usually reserved for longer-travel rigs. This 20-millimeter disparity between front and rear travel gives you a bit more efficiency for pedaling, but with extra plushness up front for cleaning notoriously technical sections of trail.
Seeing the industry is constantly evolving, it makes perfect sense to see the Mach 5.5 Carbon with a slacker, longer, and lower geometry for riders seeking a progressive trail bike that stays glued to the trail and retains stability at high speeds. The 66.5-degree head tube angle offers composure on high-speed descents, without being overly slack or wandering excessively on sustained climbs with steep, punchy sections. Just a tick shorter in the front than the notoriously long and slack Firebird, the Mach 5.5 Carbon's long top tube gives you ample cockpit room, which is especially welcome if you have a longer reach. This longer front end is complemented with snappy-short 16.93-inch chainstays. Shorter chainstays provide greater maneuverability for cleaning tight corners and uphill sections, as well as lifting the front up and over trail obstacles.
A few key details make the Mach 5.5 Carbon a truly stand-out trail bike. Delving into its carbon frame construction, Pivot employs their proprietary hollow core internal molding process with an optimized lay-up of high-modulus carbon for the lightest weight possible. This method produces a feathery-light frame (claimed as low as 5.7lb) that approaches Mach 429 SL Carbon territory, but with strength and stiffness similar to the enduro-bred Mach 6. In the rear triangle, both the seat and chainstays clear tires of 2.6 inches, which is a nice benefit for riders seeking the added bump compliance and cornering grip of high volume trail tires.
Key details in component spec make the Mach 5.5 Carbon Pro XO1 Eagle with Reynolds Wheels a truly stand-out trail bike. Notably, the crisp-shifting XO1 Eagle drivetrain features a wide range of usable gears, complete with a massive 50-tooth bail-out cog for spinning up the steepest of climbs. This build is upgraded with Reynolds Carbon Wheels, which are renowned for their stiffness, strength, and quick acceleration. This Reynolds Carbon Wheelset features a 36-millimeter width for optimal support of the wider 2.6-inch trail tires provided on this build, as well as Industry Nine hubs with a responsive 3-degree engagement for powering up and over trail obstacles.

Robin hood would have a field day

With all the 5.5 inch travel bikes flooding the market pivot had to follow along in suit. Man did they deliver with their offering. This bike takes the idea of a quiver killer to the next level. First thing they did was with tire choice went with 2.6's which i have found to be perfect. I currently ride 2.5's on my current bike, and have felt 2.8's are a bit too big. I feel at 2.6 you get a little more grab on the uphill without having to be all over air pressure to have fun. The bike as expected with Pivots development of DW link over the years is miles stiffer than the competition in the rear end. By shortening this frame, and slacking it provides a fun platform to bike on. This bike is a rocket ship on the down hill and so responsive. It definitely has a stable feel and i love the way it tracks lines so precisely. For me this is the point where it made me faster over other bikes in this category. Per usual pivots are excellent climbers as well so you wont be let down when your forced to grind in the saddle for a few hours. If you are on the fence between options, don't go 29. Keep it 27.5 semi plus with this beauty of a bike from pivot. I am always around to chat through all different options and help decide if this is the bike for you. Please feel free to give me a call anytime!

This is honestly the bike that comes the closest to a quiver killer that I have ever ridden. I had the chance to ride it down in Moab, UT which offers a pretty wide range of riding styles, from smooth and sandy to chunky, rocky climbs and descents.
This is a bike that I would consider to be the Switchblade's little brother. It is a bit more nimble and quick than the switchblade, which to me felt like a "smash through things at high speed" style bike. It is a 27.5 wheeled bike, so the smaller wheel creates a smaller gyroscopic effect which makes it feel easier to move from turn to turn and maneuver in the air. At the same time, it runs the new 2.6" width, which gets you a wider contact patch without all the extra volume of a full on plus tire. I noticed much more grip without the sometimes vague and wobbly feeling often felt with full on plus tires.
The DW link suspension is incredibly planted and confident feeling, and feels nice and progressive with a solid ramp up to prevent bottom out on big hits. The way the rear triangle and links are designed lends an incredible amount of lateral stiffness, and prevents the rear end from feeling vague or flexy.
The slack headtube angle of 66.5 degrees combined with the sub 17 inch chainstays makes for a bike that is relatively easy to get the front end up for manuals or log hops. At the same time, the steepish seat angle of 73.5 degrees prevents front end lift on steep climbs, I did not find myself needing to get way over the front end on techy climbs. Running a Fox 36 fork with 160 travel, I was worried it would feel unbalanced, but I was 100% surprised in that it feels perfectly balanced, and having the extra squish in the front end really lets you open the bike up and hit things with reckless abandon.
Overall, the bike felt incredibly planted, confidence inspiring, and somehow still efficient. I'd highly recommend this bike to anyone looking for a true all mountain bike that pedals well, but still descends pretty much anything you could throw at it. I'm really strongly considering it as the next bike to add to my stable.
Please feel free to reach out to me any time, I would be happy to help out with questions or pricing on any of these bikes. 801.736.6396x2344
