Magnetic-mechanical bottle holder for bike framesThanks to the TWIST bike base, the bottle cage is a thing of the past. Due to its flat and small design, it is perfectly integrated into the bike frame without standing out. It is easily attached with two screws to all regular bike mounting threads. Even the smallest bike frames can now be fitted with a bike bottle due to the cageless magnetic system.Fits all standard bottle cage thread insertsWeighs only 16 g / 0.56 ozFits all TWIST modules
