In addition to the new Mach6, Pivot is bringing another 27.5 bike to life as a 650b version of their carbon LES 29er. Combined with the Firebird 27.5, Pivot now has three options for the middle wheel size.
In addition to the mountain bikes, Pivot is also making their foray into the world of cyclocross with the introduction of the Vault CX bike. The carbon frame and fork will be available soon meaning you can get yours covered in mud and dirt this coming cross season.
Like other carbon Pivots, the LEX 27.5 uses their Hollow Box High compression molding system to create a lighter frame with less excess resin and better compaction of the tube walls. Like the LES 29, the 27.5 runs full internal shift cable routing with an access port under the bottom bracket for ease of installation. 
Also new for the 27.5 LES is the introduction of an XS size with the sizes ranging up to Large. Riders looking for a 21″ frame will have to size up to the 29er which runs S-XL.
The 27.5 LES has a dedicated, geared, thru axle 142×12 dropout – so no single speed options like the 29er. To keep the ride lively and quick, the 27.5 is built with short 426mm (16.77″) chainstays.
Now for something that is definitely not 650b, the all new Pivot Vault CX bike. The carbon crosser features the same carbon technology as the LES 27.5 built into a frame with “new school” cross geometry for a race tuned CX bike that Pivot claims is also competent for gravel races.
The frame is built around a tapered headtube and BB386 bottom bracket that allows for clearance of wider rims and tires and efficient power transfer. The Vault is both disc and cantilever compatible with hidden, plugged canti bosses for a clean look when running discs. The rear end of the bike has carbon dropouts with and aluminum spacer system allowing the use of 130 or 135mm rear wheels, and runs post mount discs inside the rear triangle. Shift cables are routed internally and the frame is Di2 compatible, with the rear brake cable routed along the down tube for a clean top tube for shouldering. The frame includes an oversized full carbon tapered fork with a 1.5 lower that is chatter free even with canti brakes.
The vault will be offered in XS-L (50-58cm) frames the have a 285mm BB height and 425mm chainstay length.
