Popular CST Ranges Explained
CST Schrader
The CST Schrader tubes use a wider American style (Schrader) valve and strong butyl rubber for reliable inflation and durability. Ideal if your rims are set up for Schrader valves and you want low-maintenance tubes. Every ride stays pumped.
CST Presta
CST Presta tubes include the longer, thinner French style (Presta) valve that fits many road and performance rims. These tubes are lighter and allow for finer pump interface where every gram and every valve-head counts.
CST Acimut
The Acimut series spans wire and Presta/Schrader options to match common tyre widths. Built with reliable wall thickness and solid valve lengths, Acimut tubes give you flexibility and trustworthy performance on commuter or trail setups.
CST C1854
The C1854 ‘Vault’ youngest-rider’s tyre offers kid-friendly 20-inch sizing with wire bead construction. Grip, sidewall reliability and easy tube pairing help keep bikes rolling younger wheels with safety in mind.
CST Caldera
The Caldera road / foldable-wall tyre combines smooth sidewalls, reflective elements and designs suited for sealed surfaces. It balances grip and low rolling resistance so road riders travel farther with steady comfort.
CST Jack Rabbit
The Jack Rabbit Mountain Bike tyre brings wider wire-bead tread suited for rugged trails. Strong side knobs, solid carcass and classic sizing help it cling to loose dirt and roots without breaking the bank.
