As it continues to roll through our doors in fits and starts, we've started to notice a common thread running throughout Pivot's 2017 line of trial and enduro bikes: the Phoenix. Pivot's DH firebird has proven to be something of a testing ground for suspension and geometry tweaks that are now finding their way into the rest of the Arizona-based manufacturer's line, and the latest Mach 6 Carbon Mountain Bike Frame is no exception. Considering the praise heaped on its predecessor, it may seem surprising that the Mach 6 should be importing rather than exporting tech; however, given the trend of enduro moving more toward wide, big, slack, DH-type designs, the changes bring the Mach 6 in line with the oversized trends of today's all-mountain rigs.

These tweaks manifest primarily in the rear triangle, which is where the influence of the Phoenix surfaces most apparently. The double wishbone rear triangle is clearly carrying some DH DNA, and it's combined with an ambitious upper linkage design that's 40% wider and engages the frame with larger bearings. Pivot continues the elephantine trend to the rear axle with a new Boost 148mm standard. Boost 148 ushers the Mach 6 into the modern era of enduro, where the tech seems to always be straddling the present and the future, trail riding and DH. The cumulative effect of these changes is a claimed 150% increase in rear triangle stiffness, meaning that — though the new Mach 6 leaves a wide, DH footprint — it still climbs more like a four-inch XC bike.

The DW-Link suspension design governing the Mach 6's six-inches of travel also does its part to maintain a secure climbing hold on rocky trails. Its anti-squat tendencies maintain a firm pedaling platform while cleaning terrain-riddled cruxes or picking lines with abandon across trail furniture. That responsiveness is matched on the opposite end of travel with a square-edge capacity that feels virtually bottomless, so time saved on the climbs isn't lost because of overly cautious descending.

The bike's changes are finished off with re-imagined internal routing, which accommodates mechanical groups with a more intuitive, clean system, and slots a Di2 battery in the seat tube from below for easy installation and maintenance. Some returning features worth mentioning are the PressFit 92 bottom bracket, which Pivot was on the leading edge of implementing and which finally has an equally stiff partner in the Boost rear axle.

Pivot's hollow-core internal molding process also returns for uniform, controlled wall thicknesses and material distribution. This process virtually eliminates inconsistencies and resin pooling, increasing structural integrity while targeting areas for weight loss. The frame's slacked-out geometry and stubby, 17in chainstays mean it's slack enough to challenge lines across enduro rock gardens but nimble enough to pick its way through eight-inch terrain — all while sticking climbs and roosting berms with an eagerness that begs to be pushed to the ragged edge of control.

A Hard-Charging Big Goat

  • Familiarity: I've used it once or twice and have initial impressions

The Mach 6 is a big bike. 155mm travel.... that's a lot of squish. It should be slow and sluggish right? NOPE. I was caught off guard with how nimble this felt. It's not going to climb like a Niner RKT9 or a Pivot 429SL even... but the DW-link is so efficient- I was very impressed with how quick it climbed. 66 degree HT angle seems pretty slack, but it felt surprisingly quick on it's feet too. My thoughts about the Mach6 were certainly changed after I actually got to experience it. It almost caught me off guard how fun this bike was when not bombing down- because I knew it would kill it on the downs- and yes... it did. Swallowing up babyhead sized rocks, drop offs like they're nothing. 5'11" and the Large felt like Kris Kross wearing their clothes backwards.... just right.

  • Familiarity: I've used it several times

Just finished building up my new Mach 6. I am 6'1" and went with a Large in Stealth Black/Green. Big thanks to Joe Bolton in our Retail Store Bike Shop for getting it put together. If you are ever in Salt Lake City definitely stop by our Retail Store to check out their bike selection and visit Joe (2607 S 3200 W, Suite A, West Valley UT 84119). I will follow up with a proper review once I ride my new whip a couple more times. Contact me with any questions, especially if you are interested in custom building a new Mach 6.

Gen 2 of an Enduro classic!

    I’m very excited about the second generation of this enduro classic. It’s designed for riders looking to hammer the trails both up and down on a super versatile, dynamic trail bike. A few highlights on handling that sets it apart:
    The DW Link suspension that was specifically designed for 6.1 inches of rear wheel travel which makes for an ultra-efficient climber, paired with the “hollow box” ,high compression carbon frame which is light and stiff. You can effectively assault any climb with confidence and vigor.
    With impressively short chain stays and a long front end- paired with a short stem makes for a feel as if it were cornering on rails which allows you to dive hard and fast around even the most twitchy trails. It has a very even weight disbursement and the lower bottom bracket keeps your center of gravity low making it handle like a dream. Adding to its impressive handling is the new boost standard making the bike very,very laterally stiff. The balanced geometry makes for a very dynamic descender as well rounding out this impressive bike.
    These are just a few of the characteristics of this awesome ride from an awesome company.Pivot knows what it means to be a mtn biker and you will be a believer with your first ride. If you have the means I highly recommend picking one up.
    If you have specific questions or need help configuring this bike do not hesitate to contact me direct.
