Pivot has launched a redesigned version of their Vault gravel bike which features special inserts in the seattube that allow the rider to tune the flex, which they claim results in a much more comfortable ride.
The all-new carbon Pivot Vault joins the gravel brigade with an improved tyre clearance of up to 45mm tyres on a 700c or high volume 650b rubber, plus that cunning seatpost suspension system, which they call Iso Flex.
What is Iso Flex?
The new technology isolates the seatpost from the frame, allowing for maximum compliance and comfort while maintaining the frames torsional stiffness. Iso Flex adopts the use of different rubberised inserts to allow the rider to customize the frames seat tube diameter which offers the option to fit a 27.2mm seat post up to a 30.9mm post, including dropper posts.
Inserts are secured in place with a lockring compatible with Shimano's Hollowtech II bottom bracket tool, sliding a lockring over the top to keep the post in place. Pivot claim that this technology will be significantly more comfortable over rougher terrain.
As well as Pivots clever seat tube tech they've fitted the frame with 420mm chainstays and have significantly improved the provision for 700c and 650b wheels thanks to the dropped driveside chainstay. There is also space for either a Stages or Shimano power meter.
ISO FLEX isn't the only thing providing the compliance here, the carefully chosen carbon layup and hollow core moulded frame along with its progressive new school geometry helps smooth out the ride. Pivot have added top tube bag mounts and hidden fender mounts. Adding to the versatility of the bike, the front derailleur is removable for more offroad orientated 1x gearing, included is a sleek cover to disguise any unsightly derailleur mounts.
Prices start at £2,115 for the frame only.
