The ZTR Flow EX3 are extremely resilient wheels especially for downhill, enduro and demanding trails. They have been specially developed for use in extreme conditions. Equipped with a special hollow chamber system with additional connecting struts to meet today's downhill, enduro and e-bike requirements. The Flow EX3 combines the 29 mm inner width and the robust 6069 aluminium construction of the Flow MK3 with the incredibly stable triple hollow design of the classic Flow EX rim. The result is a new rim shape that strikes a perfect balance between radial compliance and lateral stiffness, setting a whole new standard for durability and shock resistance.
