Stan's Flow rims have had a long history as the go-to trail and all-mountain wheelset for riders around the world, and the Flow MK3 continues the evolution. Stan's Flow MK3 wheels have claimed victories in both World Cup DH and Enduro World Series races, while still being light enough for all-day trail rides. Stan's patented tubeless bead socket technology offers the easiest and most secure tubeless setup in the business. The patented low-profile shape of the rim also resists pinch flats and reduces overall rim weight. The Flow MK3's 29mm WideRight internal rim width provides the perfect balance of tire stability and traction. Laterally stiffer and more durable, the Flow MK3's 6069 alloy is also lighter and stronger than conventional 6061 alloy. Born and bred for control at speed and perfect for technical trails, Stan's Flow MK3 in a class by itself for trail and all-mountain performance.
