Vivente carries stock of frames and forks and any thing unique to the VWR bikes. Most components used on the bikes used are from premium-level brands which have their own distributors around the world. They have territories within which they are responsible for holding stock. Although VWR does hold stock of many items it does not wish to be a mainstream supplier of bike parts. Hence it does not publish a retail stock list. The message is, if you need something there is likely to be a supplier other than Vivente and your bike shop will help you to obtain what you need. If you are in trouble, particularly if you are on a journey somewhere, don’t hesitate to check with Vivente by email. We respond quickly.
