CST Bicycle Inner Tube (12" – 29"). Choose your size and valve – each option shows the matching box, so you can check it against the size printed on your tyre.
SV = Schrader valve (same as AV, the car-type valve). FV = Presta valve (thin French valve).
Bent valves are for e-bikes, scooters and small wheels.
Longer valves (60 / 80mm) are for deep rims.
A range such as 1.90/2.125 fits any tyre width inside that range.
Sizes marked non-CST brand are a different brand with the same fit.
Installation available at our Woodlands (Primz) and Yishun (North Spring Bizhub) stores. Not sure? WhatsApp us a photo of your tyre sidewall.
