The Holy Rail
The Holy Rail is a modular mounting system that enables flexibility of mounting accessories to your bicycle.
Simply attach the rail to your bottle cage mounts on either your down tube or seat tube and get creative with repositioning and mounting accessories and spares to your frame. The system uses standard M5 x 0.8 bolts meaning existing bottle cage accessories are compatible with the system.
