The CST Cosmo is a big-volume 29-inch urban tyre for e-bikes and cargo bikes: a smooth, stable ride at low pressure with an intelligent tread that keeps control on busy streets, plus a Defender Cobweb puncture layer.

Highlights

  • High-volume 62 mm casing — comfort and stability at lower pressures
  • Defender Cobweb / EPS puncture layer — fewer flats on city glass and debris
  • 120 kg load rating — suits commuter e-bikes and light cargo duties
  • Wire bead single-compound tread — long-wearing and easy to fit

City comfort

CST designed the Cosmo for riders who want a smooth, comfortable ride with exceptional stability, with a tread pattern crafted for control on demanding urban surfaces.

Fit and compatibility

29-inch / 700c (ISO 622) clincher rims; run with an inner tube. At 62 mm wide it needs a frame and fork with generous clearance — typical of e-cargo and modern urban e-bikes.

Need it fitted? Tune Cycles can fit and true it in the workshop, or ship it to your door.

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.
