The adoption of quick-release devices on bicycles has led to a heightened potential for injuries due to front wheel separations. A new ASTM International standard defines the performance of primary and secondary wheel retention systems in order to prevent unintended wheel separation.

The new standard, F2680, Specification for Manually Operated Front Wheel Retention Systems for Bicycles, was developed by Subcommittee F08.10 on Bicycles, part of ASTM International Committee F08 on Sports Equipment and Facilities.

David Montague, president, Clix Systems Inc., and a member of the F08.10 task group that developed F2680, says that the new standard defines the performance of primary and secondary wheel retention systems, with the focus on preventing unintended wheel separation.

“We hope F2680 will help to cause forks and wheels used together by bicycle manufacturers to be more compatible and less prone to unwanted wheel separation,” says Montague, who notes that complete bicycle assemblers as well as hub and fork makers will find the standard beneficial.

“Bicycle riding is one of the most popular recreational activities in the world,” says Montague. “When a bicycle wheel separates during riding, the resulting injuries can be substantial. Therefore, any standard that helps to reduce unwanted wheel separations could have a major impact on many riders around the world.”
