Whether our route consists of asphalt, gravel, or dirt terrain, the Pivot Vault Pro Ultegra Di2 Gravel Bike is built to take on it all. This bike is constructed with a full carbon frame with a hollow core internal molding technology, providing a high stiffness-to-weight ratio and all-day comfort. Pivot's patent-pending ISO FLEX seat post technology keeps us pedaling with ease as we rack up the miles. Optimized for speed, the Vault Pro features internal cable routing for a sleek, aerodynamic look and geometry built for power. We experience quick, smooth, and reliable shifting performance with the Vault Pro and its Ultegra Di2 groupset. It features a 48/32T chainring with a 12-speed, 11-34T cassette, providing us with a wide range of gear ratios for whatever terrain stands in our way. A BB386 EVO bottom bracket creates a more powerful and rigid feel during the ride and increases the rear wheel's tire clearance. Its wheel setup is complete with Maxxis Rambler TR Tan Wall EXO 700 x 40mm tires, but it's able to fit up to 700 x 47mm to ensure our setup is ready for an epic adventure.
