Just bought it yesterday. This bike is originally sold by [Bikesdirect.com](https://bikesdirect.com), the early days online direct to consumer shop before Canyon rolled in and dominated the business model from better marketing strategy.
This bike is well equipped, with Ultegra groupset, SL-K hollow carbon crankset, Richey components throughout, Cane Creek SCR-3 caliper brakes, and a purpose build endurance geometry. Stepping on the pedal gives you a smooth but firm ride on the 700x23c tires, which are perfectly fine.
The bike can take tires up to 28c and anyone who found it would be really happy with the ride quality.
