Product DescriptionThe name is appropriate; by that we mean the "mach" part. All we can think of is how fast we could ride this bike, and the Pivot Mach 5.7 Carbon is more ready to rip than ever before. Imagine taking a half pound from the frame weight of the alloy version of this bike. Make it stiffer too. That's exactly what Pivot Cycles did. And while the 145mm (5.7") dw-link rear suspension works as beautifully as ever, the frame is far more attractive than the alloy model, with its sweeping curves and smooth tube junctures. Pivot has taken advantage of the latest molding technology to get the frame weight down to 5 pounds with the rear shock. This means that sacrificial internal molds get used to provide better compaction of the laminate and to create a smoother inner surface. All of this adds up to a stronger and lighter bike without the wrinkles and excess resin that used to plague intricate monocoque layups. While the front triangle is noticeably smoother, the rear end is where you'll see the greatest differences in design attributable to the use of carbon. Instead of two struts connecting the set and chain stays, there is but one on the left side. And there isn't a seat stay bridge either. These changes help to increase the mud clearance over the alloy Mach 5.7 frame. We always like that. Up front it gets the same tapered head tube, and it allows Pivot designers to shape a massive down tube for steering stiffness.Out on the trail, the Mach 5.7 Carbon glides over rocks, roots and ruts, yet still remains firm while hammering out of the saddle. Firm, efficient pedaling and serious bump compliance? It's possible to have both thanks to the dw-link suspension with its anti-squat characteristics. When you're on your bike, the center of mass is somewhere near your belly button. Every time you accelerate (ie. pedal forward), this mass shifts rearward, loading the rear suspension. The dw-link counteracts this transfer to minimize your impact on the rear suspension.This is why Pivot is able to get such a lightly damped tune on the Kashima Coated RP23 rear shock from Fox. With the dw-link controlling unwanted suspension squat, the lightly damped shock can respond with ultra-sensitivity to the demands of the trail. As a result, the Mach 5.7 Carbon is capable of soaking up big square edged hits and minute trail chatter alike. Perhaps the best trait of dw-link rear suspension is how well it absorbs bumps while climbing at low speeds. This means more comfort and better traction. The Mach 5.7 Carbon has a flatter spring curve than the Mach 5. So even though the difference in travel between the two bikes is fairly small, the 5.7 has a plusher ride and a more bottomless feel at the end of the stroke.There are a few other details that emphasize the efforts towards optimizing frame stiffness. One of the easiest to see is the BB92 pressfit style bottom bracket. The extra width in the shell does two things -- 1) It allows the frame designers to connect a massive downtu

Strengths: Pedals like a XC bike but 150 mm and 67 head angle kills on the way down. Very light 26 lb for a long travel bike. Great suspension, especially the rear. One of the most agile, fun playful bikes I've ridden. Great component build. Tricon wheels Shadow Plus rear derailleur Kashima fork/shock XT brakes with finned pads, even the seat WTB is great.
Weaknesses: Small 26 inch wheels. Really a double edge sword here. Less stable and not a good on smaller chunder, but more nimble. Not my favorite tire choice and should have come tubless on those great wheels.
Here is my take on the wheel size and why I like this bike so much. 29ers roll over stuff better so you can use shorter suspension making them pedal better, in general. But you loose agility and when the going gets really rough you miss the suspension travel. 26ers can roll over stuff just as well if they have more suspension, but you loose pedaling efficiency. 27.5 felt very close to the 26 and not really gaining the advantage of the 29er.
So the Pivot Mach 5.7 has enough suspension to roll over everything and it is so light and so efficient pedaling that you can just power through the chunder on the way up. It's way agile and so light it accelerates well coming out of corners or up short steep climbs. I feel like everything is a trade off, bigger wheels vs agility. This bike strikes the perfect balance for me. It is light enough and pedals well enough with enough suspension that I don't feel the need for bigger wheels. And when it turns down, it is a real blast, railing courners, jumping off stuff, just playing with the trail like I can't on my Superfly or the Stumpy I have ridden.

Strengths: THIS REVIEW IS FOR A PIVOT 5.7 CARBON WITH A 650B CONVERSION.
Strengths: Better bump roll over - smooths out the rough trails, allows faster speeds over the bumps, less hangup effect on bumps. Better stability and traction. Allows rider to rail corners/switch backs aggressively with more speed and confidence. 650b has slightly less rolling resistance than 26 inch wheels - so the science says - but not very noticeable - its nothing like the night and day difference when comparing 26 inch wheels vs. 29 inch wheels. 650b wheels on the Pivot Mach 5.7 C still feels flickable, quick, agile, and still has the fun factor of 26 inch wheels.
Weaknesses: Slightly higher bottom bracket - I can feel it but it does not really compromise the handling for the worse. The bike feels just slightly twitchy because I think the chainstay length of the Pivot Mach 5.7 C is just a tad too short for 650B wheels, but of course the frame is designed around 26 inch wheels. Rear wheel clearance there is approx 4-5 mm of clearance between the tire and chainstay box section bridge.
Rear Wheel Travel had to be reduced. I had my Fox Rear Shox rebuilt/modified - 5mm spacer to reduce the stroke/travel. The Stock Fox Rear Shock has a 2.25 inch stroke which allows up to 5.7 inch rear wheel travel. The modified rear shock with a 5 mm spacer - shock stroke is now reduced to 2.05 inches which now changes the maximum allowable rear wheel travel to 5.19 inches. The rear shock had to be modified to allow clearance between the rear tire and the back of the seat tube - otherwise the stock (unmodified) rear shock, if it were to bottom out, the tire would slightly rub against the back of the seat tube right at the point where the front derailleur cable guide is located.
Another weakness is limited tire choices in 650b and a rear tire larger than the 2.25 might not fit the rear - I have not tried any other tire size yet.
Due to modifications warranty issues can be voided.
The larger wheel advantage drove me to convert my Pivot 5.7 Carbon to a 650b - Im willing to try anything that might be better. Looks like Im going to keep my 5.7 C with 650b wheels, but when Pivot comes out with a 650B specific frame, (hopefully its carbon with 5.5 to 6 inch travel) Im going to get me one because im sure it will perform better that the 5.7 C.
The Pivot 5.7 C does have enough rear tire clearance with approx 4-5 mm of gap between the tire and chainstay bridge box section (this is with a 2.25 Schwalbe Racing Ralph tires). The Rear shock will need to be modified with reduced stroke/travel to prevent rubbing of tire against the seat tube if the rear shock where to reach full travel or bottom out. If you have a Fox fork (for 26 inch wheel) there will be enough tire clearance depending on tire size, with a 2.25 Racing Ralph I have 6-7 mm of clearance, though I might switch to a Schwalbe Nobby Nic and should still have enough clearance.
I believe the performance of the 5.7 C with 650b wheels is slightly improved and worth the $$ for the conversion. Its still a blast to ride. It did take some getting used to. The 5.7 C still retains its awesome performance: pedaling, acceleration, quickness, flickability, but with improved bump roll over, less rolling resistance (barely noticeable), better traction and cornering stability and most important of all the fun factor is still there. Downside is the slighty reduce rearwheel travel :( but I guess life as a mountain biker has it compromises with bike upgrades or modifications.
Sorry to Francis, Greg, everyone at MTBR, and users/visitors to MTBR. I was not sure where to post this review. Maybe there needs to be a section for 650b conversions.

I bought the version XT/XTR, and I’m amazed, my last bike before the Pivot was the Specialized Stumpjumper FSR (before that I had, trek cannodale and GT), and this bike is waaaayyy better, has more travel and the Dwlink system is great in the climbing sections, either technical or not. I’m from Ecuador and in our privileged biking geographic, this bike does everything great, especially in the downhill sections this bikes is very maniobrable and suck every obstacles in the road, sometimes you got too much speed and when the drops shows in the way, this bike laughs of them.
Amazing Very very recommendable.

Strengths: Incredible bike. Climbs better than the xc bike I had (RM 70 msl carbon that was stolen; bought 5.7 as replacement) and descends for me like Pivot Firebird (which I had and traded in to get my wife a 5.7). The Firebird was probably more than I needed given my skills (limited), but in terms of going down, the Mach 5.7 feels basically like a super light Firebird. I don't know how Pivot does it. Best of both words. I can ride up and down terrain that I couldn't clear before.
Weaknesses: I put on Nobby Nics instead of the stock Kendas.

Strengths: Climbing in or out of saddle, rear wheel traction, small bump compliance, ability to ride through rough terrain at speed while seated and in a higher gear than any other bike I've ever been on. Feeling of total braking and handling control while descending. DW Link rear suspension is awesome it lives up to all the hype and more. Rigid frame, drives like on rails.
Weaknesses: Kenda tires are quite heavy, my XTR build was 26.0 lbs after changing the rear tire to a Racing Ralph and changing the grips the bike weighed in at 25.0 lbs yesterday. Although the digital scales were different I believe both were accurate.

Strengths: The bike is really light. Power transfer feels just about right and the suspension keeps the bike nice and planted. I feel really comfortable on this bike and can't wait to get more aggressive with it.
Weaknesses: 6'-0" tall and I'm on a large. I have wide shoulders so I put a wider bar and not it feels perfect. I also changed out the grips because they felt cheap and the sat was too narrow for my backside. Overall just 3 minor adjustments and now it's perfect.

Strengths: Give 6++++ not 5, Frame is excellent with down tube design, carbon finishing, handling, head angle with 150mm folk. Specially I'm very impressed for down tube design. It gives to me a sense of stability when I'm riding. Excellent finishing of carbon frame with printings and eggshell than I thought with pictures before I got. Handling is perfect.nobody can complain for this handling.
Weaknesses: - cable route around seat post : sometimes the cable hit my leg when I have pedaling. of course I fix this problem with cable tie temporary but need get permanent solution.
- No badge in head tube. I need a badge for my bored head tube such as al. 5.7.

Strengths: This bike is light (27.5 lbs), but not that much lighter than my Motolite (28lbs). Slack headtube angle. Very active suspension. DW link works once it is set up correctly in tandem with the fork pressure.
Weaknesses: Front end too light? Coming off an El Guapo with the heavier 160mm Talas fork the bike feels like a toy in comparison. Only time will tell how this bike holds up in the gnarlier sections. This is the only part where I have held off so far, otherwise the bike excels.
Last December, just like Dj who put in the first review, I demoed the 5.7 Carbon as a lark with 2 friends in SoCal, not intending to buy anything, but knew instantly that this bike could be a lot of fun. Even though I had just built a new bike at the beginning of the year and I try to go at least 3 seasons before getting a new one I was encouraged by my beautiful wife to order a new frame (I'm twice lucky).
I now have 5 rides on it in a little over a week. I built it by transferring all my motolite parts, so essentially although the bike is light, it is not significantly lighter than the motolite. It could be stiffer than the motolite, but I've never been a good judge on any succinct differences responsible. For me differences show up in what the bike lets me get away with and there the 5.7 really shines. I essentially wanted a lighter El Guapo and that I got in spades. The margin of error is the same, so that I can push this bike to extremes. 3, 4 and 5 foot drops are a pleasure and don't have to be executed with perfection so there is room to go higher without fearing a crash. It took me 5 rides to perfect the set up (fork pressure, shock pressure, stem length) but I now have it where it rides uphill very well (something that the EG with CCDB even with the additional weight excels at as well). The DW link difference is there as well. I tend to mash the pedals and the motolite under heavy pressure tended to cause a lot of bobbing that is absent in the 5.7, rocky sections are now a pleasure and don't sap my strength.
Having ridden the EG for the last year the only issue I have going back to the 5.7 is how light the front end is in comparison. Going through rock gardens at speed with the suppler 150mm fork will need getting used to, but it is so much more agile that it those circumstances a change in direction is altogether possible.
Like Dj, I want to give kudos to the Pivot demo team. Dj covered most of what I could say as well. I will add that the addition of a female with riding experience was a definite plus for those women that might enjoy the sport. I happened to see the Specialized Demo that was held on Sunday the19th in Newbury Park and although they had as many bikes, no women were to be seen to assist with bike fittings.
Ultimately, these toys of ours are not cheap and a luxury. As such they are nice to have but not essential. A level of guilt at my extravangance is ever present especially in the times we live in. Therefore, when building a new bike I always feel pressure that it ultimately be worth it, that the end result is a bike whose qualities are a noticeable improvement, not an emptier wallet. From my perspective, even after only a week of riding, the Pivot 5.7 Carbon is indeed worth it to me.

Strengths: Light - 5 pound frame weight in size small. Fast with efficient pedaling dynamics and Smooth - active/plush suspension due to DW-Link. Fox RP23 rear shox with tuning options and Kashima Coating. Stiff and very stiff. Looks - I like the matte carbon finish - I have the frame with the blue accents. Climbs like a goat, just as well as my Mach 4 but better than my Titanium hardtail. Descents are fun on this thing - I look for the roughest ugliest lines because it just plows through without hesitation - point and shoot - this bike will cause accelerated erosion to rock gardens. Wheels stay planted - eats up rough terrain climbing and descending while holding its line. Can hit tight corners and switch backs well with good stability, control and traction.
Weaknesses: Expensive, but price is similar or less compared to other bike companies carbon trail bike offerings. A lot of blogs and forums mention different opinions about the graphics - love it or hate it - but blogs and forums can be a lot of BS. First off, the frame looks way better in person vs. pictures seen on online, catalogs, magazines, etc. Pictures don't do justice of how the bike looks in person. The graphics are ok, but I don't mind the graphics because I don't plan on entering my bike in a beauty contest, bike show, nor use it to pick up chicks - my wife likes that one, and nor do I care about turning heads on the trail. I do think the Pivot name on the bike is a bit over stated (I counted 10 times). I would personally prefer a simple minimalistic look of a plan matte carbon finish with just a white outline Pivot name/logo on the down tube, head tube badge logo and of course you gotta include Dave Weagles DW-Link logo somewhere on the frame. I can't think of any performance weakness.
This bike is light. I mean you can flick it, whip it, jump it, throw it around - I mean its pretty quick, responsive and nimble. It accelerates fast. Minimal to no Pedal bob. The suspension is plush and buttery smooth through its travel most likely because of the Kashima coating, DW- Link design, and Fox RP23 shock. This bike can handle steep rough rocky climbs without the front end lifting off and no front end wandering. Awesome front end and rear end traction. With the 5.7 Carbon, I was able to easily ride through rough technical terrain that I used to sometimes put my foot down or hike a bike when I rode the above mentioned XC/trial bikes. Descends with confidence. Active suspension with good small to big bump compliance. Tracks the trail well no matter how twisty or technical. Carbon helps dampen the trail chatter, carbon is stiffer/lighter, and the ride of a carbon bike is less fatigue on my body vs. my aluminum Mach 4.
This is my first Trail Bike that has more than 4 inches of travel. Im used to bikes that are XC oriented - 4 inch suspension, hardtails, steep head angle, light weight, etc. So Im used to bikes that are fast, quick handling, climb well, pedal efficient and light weight - the Pivot Mach 5.7 Carbon has all of those ride characteristics plus a lot more making it a more versatile trail bike capable of handling a variety of terrain.
Pivot Customer Service is A+: everything from the phone calls, emails and demo rides (the Pivot guys at the demos rides were very helpful to a lot of experienced mtn bikers who wanted to test ride the bikes, but what I thought was more awesome was how they helped and treated a lot of novice mtb riders and even some roadies who wanted to try out the mtn bikes - many of whom were not sure what type of bike to try). Pivot even gave away T-shirts at the demos if you test rode a bike. Pivot answered all my emails in a timely manner. Even the man himself, Chris Cocalis emailed me back re: my concern about the integrated in molded post mounts for the rear disc brakes. When I was in the middle of building up my bike w/ grease n dirt on my hand some of which got smothered over my iphone, Pivot was able to answer my questions about building/setting up my bike. Thanks Pivot, Keep up the good work and keep making awesome bikes. It wont surprise me when they come up with a Carbon Mach 4, 429 or maybe 529, and Firebird - The DW-Link w/ eccentric pivots looks interesting.
