Designed in collaboration with Downhill Mountain Bike Legend, Chris Kovarik, also known as Karver.

Chris Kovarik has been a strong figure in the Mountain Bike world since he first appeared on the World Cup racing scene in 1998. Under his belt he holds several National, International and World Cup wins as well as track records and countless podium appearances at all levels of the sport. He still holds the record for the largest winning margin in World Cup history. Chris’s aggressive riding style make him a favourite with the media and his skills on a bike are owed to his natural ability and years of dedication and experience.

For many years, Chris has put his bikes and equipment to the test and continues to do so. After many years of fine tuning his machines, he began to search for ways to eliminate noise. After 7 years of experimenting with zip ties, velcro, strips of rubber, PVC piping, rubber O rings and other materials he could find, the idea for our STFU devices was born.

The complete range of STFU drivetrain damping devices are designed to keep your bike running quiet and efficient while minimizing wear.

Designed and tested right here in Whister BC, Canada
