We like the idea of the drive belt blending in with the back frame triangle. Unfortunately, the laws of physics prevent that option. Due to Schindelhauers patent pending SBP-System the opening is well hidden and changing your drive belt is easily being done. A fixed connection between seat and chain stay is achieved by applying Schindelhauers positively spool piece in wave form which reflects the design of the drive belt. It can easily be removed and also reinstalled. By applying a continuous screw connecting all components, the original stiff state is restored and it looks like as nothing has ever been changed. No more an annoying quantity of diverse transmission or screw connection affecting your eyesight- just pure aesthetics of the invisible remains. If it involves a Schindelhauer Bike, this application goes visibly unnoticed. We are very proud of that..
