Fit and compatibility

Pick the size whose width range includes your tyre (printed on the sidewall). Schrader valves need an 8 mm rim hole; Presta needs 6 mm or an adaptor in a Schrader rim.

Pick your option from the dropdown; price and stock update to the exact variant.

CST backs its tyres and tubes against defects in materials and workmanship, assessed while serviceable original tread remains. Road hazards (cuts, snags, punctures), plug repairs, under- or over-inflation, overloading and incorrect mounting or rim fit aren't covered.

For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you. This cover is in addition to your rights under the Australian Consumer Law.
