The Inside Line Downhill Mountain Bike Club (Inside Line) is a family friendly group of downhill mountain bikers based in South Australia. The club’s main role is to support the downhill discipline of mountain biking in the state. Inside Line runs the State Downhill Series and State Championship races as well as hosting national level events in the downhill and gravity enduro formats. We are also extremely active behind the scenes, advocating for trail development, maintenance and sourcing finance to fund projects that keep the scene buzzing! For more information about our club, visit the About Us page.

Inside Line relies entirely on volunteers to get the job done. There is a volunteer behind everything that needs doing, from event planning through to driving shuttle buses and there is always room for more help!

If you would like to lend a hand in any way it would be graciously accepted. Contact us to join the team.
