Freakynuts makes my life easier!

The Fox40 Adapter makes my life much simpler. I now dont have to carry arround 4 front wheels for my DH and Enduro to be prepared for muddy and dry soil. The Team was really helpful in improving the product upon request. Thanks a lot!

Absolutely incredible product!

This innovative solution has saved me both time and money. As someone who owns multiple bikes and three Boxxer forks, I could not be more impressed. Thank you for creating something so fantastic!

Moin! Mega Konzept!

Ich musste mir schon extra eine neue Felge kaufen nach dem Gabelwechsel und habe jetzt zwei unterschiedliche Felgen, was mich total nervt. Aber mit diesem Adapter kann ich meinen alten Laufradsatz weiterfahren.
