The official program that guarantees buyers of used Lightweight wheels absolute safety and peace of mind is called CPO: Certified Pre-Owned. Within the framework of a careful selection process, eligible wheels are selected. These are wheels that, for example, served as exhibition pieces and were never ridden on the road, test wheels or carbon rims that were purchased from us under Crash Replacement or Wheel Protection regulations. Our qualified service center team prepares the wheels for resale after the selection process and performs a thorough check-up. Depending on the needs, the bearings are replaced, brake tracks are renewed, the wheels are freshly centered, the freehub service is performed or even a new sticker is applied. A one-year warranty applies to all CPO wheels from the date of purchase.
