Our new "jade black" 8/11 speed bike is a real classic. The Shimano Alfine internal hub gear seamlessly integrates into the sleek design of our glossy black bike. Leather components from Brooks and high-gloss polished rims underline the value of our city bike. We use high-quality Columbus tubes for the hand-welded frame. The maintenance-free, lightweight, and quiet belt drive (Gates Carbon Drive, CDX) is impressive. Smooth running, a small evolution! Also new are our aluminum pedals and headset - both CNC machined and equipped with durable industrial ball bearings.
