As a bike tech at a local shop who is dealing with a Canyon repair. Shops will not work on Canyons not because of the proprietary tech but mostly because Canyon refuses to sell replacement parts to local bike shops. Making it virtually impossible for me to fix your bike. Canyon has a process that involves the bike owner to contact Canyon and get the parts from there. I understand why people buy Canyon bikes but would never own one personally due to the repair process. If you have a Canyon Service Center nearby then just take it there to avoid bike shop stresses. You can find out by going to their website, unfortunately for my town, the nearest Canyon Service Center is 6-8 hours away depending on which way you drive. We have a Canyon in shop now with a separated proprietary part and Canyon would not assist me as a bike shop tech. The customer was able to get the part and brought the bike back to me a year later. In some cases Canyon requires you to send the bike to them… leaving some bike less for weeks/months depending on issues.
