Who in the land downunder is Overfast?

Overfast was born from a crew of restless engineers with a single obsession: killing every gram between you and the finish line. To them the real barrier to speed was never the rider — it was the parts holding you back. So they built their own, machining ultralight carbon components that do one thing better than anyone: go faster.

Now charging across Australia, Overfast arms riders who refuse to settle. Racers, climbers, and anyone chasing a new PB on the local loop. Engineered without compromise and built to take on brutal heat, rough chip-seal, and endless k's.

No rules. No limits. Only faster.
