It was built from frame up, has gone through many upgrades and different setups. Drivetrain is modified with a ratio technology actuator, so you get 12 speed eagle gearing with drop bars without electronics shifting. Brakes are cantilever Tektro cr720, super stiff and will stop on a dime if you want them to. Comes with Nir wheels, it's tubeless and fits up to 40 mm tires easily. Chris King No Threadset headset, carbon seatpost, alloy pro ergo bars and Easton cranks. It comes with both front and rear dedicated racks, it can fit 2 panniers on the front and two on the back I've used as my touring bike, gravel bike and commuter at different times, . It's a smooth ride and corners on rails .
