SQUAMISH, British Columbia (BRAIN) — The Canadian components maker OneUp Components has been granted a U.S. patent that applies to its 42-tooth sprocket, which can be used on 10-speed cassettes to create a single-chainring drivetrain with an acceptable low gear. The company said it is now accepting applications from those who want to license the patent.
While there are several other companies offering 42-tooth sprockets for similar applications, it's not clear whether they would be violating OneUp's new patent. OneUp also said a Canadian patent is pending.
