8 1/2 x 2 CST Inner Tubes – when it’s time to keep those wheels turning, you’ll want quality you can trust. These CST inner tubes are the unsung heroes of your bike, fit to handle whatever road (or misadventure) comes your way. Ideal for clincher tyres and rims, they’ve got reliability and value down to an art—much like a perfectly planned escape from that awkward family gathering.
Available exclusively with Schrader Valves, these tubes are the right fit for your adventurous spirit—no more worrying about wobbly rides!
Features:
With CST's long-standing reputation, these tubes are more dependable than your mate who says he’ll hold your pint while you hit the loo. So gear up, get out there, and take on those winding roads; your bike will thank you for it!

Orders $99 or more ship FREE—because spending more should mean saving more.
Non-Rural: $8.99
Rural: $13.99 (because those scenic backroads take a little longer to reach!)
Non-Rural: Ships in 2-3 days
Rural: Up to 5 days (we blame the sheep traffic)
New Zealand only—for now. One day, we might take over the world.
