Pivot's Vault Frameset is all-new and adds some interesting features and designs that further extends its all-around, ride anything capabilities. It looked closely at the ever-popular gravel scene, didn't neglect its 'cross roots, and confirmed its placing as a mountain biker's road bike with some innovative frame details that simply make it faster, more comfortable, and more capable than ever before. Its design goals were increased compliance, more clearance, and extra mounts that boost its performance over gravel, on the cross course, and the weekday world's loop. A quick glance at the tech specs reveals all of the current frame standards while a peek at the geo numbers show a frame that offers added stability at speed over rough terrain. That conspires with a new carbon layup that offers a responsive, comfortable ride with the efficiency we've come to expect from Pivot.
First up is the bike's geometry. Pivot has carefully refined it for cross, gravel, or road and it pretty much excels on any surface. Thanks to its new dropped chainstay design, the stays sit at a decidedly stubby 420mm, whacking some 5mm off of the already impressive 425mm length found on the previous versions of the Vault. This not only helps keep the frame nimble and the wheelbase tight, but it also makes for more efficient power transfer. You'd be excused for thinking the shorter stays limit tire clearance, in fact, clearance is increased everywhere from the massive 700x47mm or road plus 650x2.0in tires to the more welcoming crank and chainring clearance, right down to the non-driveside crank clearing crankarm based power meters.
The stays complement the returning BB386EVO bottom bracket shell that reduces watts lost to waggle and flex while sprinting out of hairpins or hammering up climbs that amount to 5-digit elevation days. Also returning is the tapered head tube, oversized steerer tube, and 12mm thru-axles front and rear that also contribute to overall stiffness while keeping the Vault tracking like it's on rails on smooth canyon roads and flowing hardpack alike. The bottom bracket also drops half a centimeter across all sizes providing more point-and-shoot stability for confidence powering through sandpits and down steep, washboard riddled descents.
Pivot also refined the carbon layup and tuned the tube shapes to impart more comfort and compliance while still relying on its tried-and-true hollow core internal molding. It involves laying-up and compacting the carbon around an internal form, ensuring that the frame doesn't carry any additional material in the form of resin pools or wall thickness inconsistencies. The process makes for greater structural integrity, which our practical side appreciates, and a lighter, stiffer frame, which satisfies our less practical hunger for podium places. The lay-ups are also tuned specifically for each size, allowing Pivot to imbue each size with the same level of eager responsiveness without undue weight gains. Requiring a larger frame no longer comes with the penalty of a noodly, poorly tracking ride.
There are of course some new frame details we'd be remiss for not mentioning and one is its patented Iso-Flex Technology that fits 27.2mm seatposts. Iso-Flex is essentially a shim that sits in the seat tube and isolates the post from the frame for next-level comfort without compromising frame stiffness. Now you can remain seated and dish out all of the watts without getting bucked over rough patches. Furthermore, the frame is compatible with dropper posts if you're looking to take your monster cross to the next level. Other notable features include its 1 and 2x drivetrain compatibility with removable front derailleur braze-on and integrated cover, trap door on the bottom side of the downtube for easy cable routing and Di2 battery storage, top tube bag mounts for the longest days, and hidden fender mounts for staying clean during all season riding.

I recently built up one of these frames with a GRX 1x setup. It has been great. I have both a road and gravel wheelset and the bike is very fast, stable, and comfortable for both. The ISO Flex must be doing what it's supposed to because even sketchy gravel descents seem smooth. I got the Sandstorm frame, which is a bit bland, but added some orange bike bling so it looks great. Frame was easy to setup, route cables, etc. Highly recommended.

After researching a new gravel bike to replace my Niner BSB RDO that I got from Competitive Cyclist over 3 years ago, I settled on the Pivot Vault. It seemed to check a lot of the boxes that I was looking for: clearance for wider tires, lively handling, internal cable routing, option for 1x or 2x, and a lightweight frame. Building the frame up was easy. Pivot did a really nice job with the cable ports and having the bottom bracket cover to help with routing. I transferred most of my components from my Niner, but did learn a few things after I built this up. There was not much tire clearance between my WTB Nanos (measuring 45mm) and my Ultegra Di2 FD. I did some investigating and opted for the GRX Di2 FD. I highly recommend going that route if you plan on using Di2 on this bike. With GRX FD, there is plenty of tire clearance and I could probably fit one up to about a 47ish. I also opted to get the GRX Di2 RD too, so I could run a bigger cassette if I wanted too. So, how does it ride? One word...FUN! I enjoyed my Niner BSB (which was more CX geometry), but the Pivot seems more lively while also feeling sure footed. I wondered how well their ISO Flex seat post system would work and I have been pleasantly surprised. It does take some of the bumpiness out of the rear end. I have primarily ridden the Pivot on fire roads, including areas with a lot of erosion channels from the winter rains. It feels nimble on the single track I was able to test it on. This bike also responds well when climbing either seated or out of the saddle. While I have only had the opportunity to put a few hundred miles on it, I am happy with my purchase decision.

What is the frameset weight of a Small including the isoflex shim? Does the frameset come with axels?
