STFU Bike is a collaboration between two Australian friends living in Whistler, Canada. Chris Kovarik is a multiple downhill World Cup winner, still holding the largest winning margin in DH racing history at 14 seconds against 2nd place Cedric Gracia in Fort William in 2002. Chris has been testing his bikes and equipment and continues to do so.
After many years of fine-tuning his machines, he began looking for ways to eliminate noise. After 7 years of experimentation, the idea for our STFU device was born. One 3D printer, a bunch of CAD and prototypes, 2 seasons at Whistler bike park and this is the end result. The ultimate gadget that stops chain chatter and turns your bike into a silent bike.
