No worries! Our new HUSKE Fork Mount is designed to easily adapt to different hub standards. In fact, it's right there in the name: HUbs Standards Keep Evolving. If you happen to get a new bike with a different hub standard, or manufacturers introduce new ones in the future, we'll develop a new HUSKE plug to make it compatible with the existing HUSKE base. The good news is that all our new racks come with the fantastic HUSKE Fork Mount, and you can retrofit it to your old racks since it uses the same bolt hole pattern as our previous fork mount.
