When the designers of German carbon fiber outfitter UBC were given “carte blanche” directly from their CEO Ulf Bräutigam, it was clear that the Coren would become something exceptional. The result is a high-tech single speed made of T1000 carbon fiber that is usually reserved for Formula 1 with a Gates Carbon Drive belt system. Each frame is handmade and each bike weighing 7.7kg (17lbs) requires 40 hours to be made. Price tag: €25,000 ($32,500). Enjoy!
