Generous tyre clearance — runs the wide rubber Mackay's gravel actually wants
Why You'll Love It
Mackay's gravel scene runs through Pioneer Valley, Eungella forestry roads, and the QLD State Champs course at Sarina — and this is the bike that makes all of it possible without compromise. The Crux is built for fast gravel, not tour-loaded touring. Generous tyre clearance lets you run the wide rubber Mackay's surfaces want; race-gravel geometry gives you the position you need when you're chasing a finish. We sell every Crux through a sizing + fit conversation in-store at Mackay Cycles — Retül session available if you're new to gravel geometry. Pre-delivery service, 6-week first-service, and a phone we actually answer when you need it.
