This listing is made for a specific tyre width range and valve length as noted in the product title (for example 18-28C or 18-32C, with either a 65mm or 85mm valve), so it's important to check your tyre's printed size on the sidewall and your rim depth before ordering. Using a tube outside its rated width range, or a valve too short for your rim's depth, is one of the most common reasons for a poor fit or early failure, so please match the size on this listing exactly to your tyre and rim.

TPU tubes are generally reported to handle small debris and gradual wear reasonably well and offer strong air retention, but because the material is thinner than butyl, they can be more susceptible to pinch flats during fitting if levered or seated carelessly. For riders who prioritise low weight and fast rolling over maximum puncture immunity, this is a good ultralight spare; if you ride frequently on glass or thorn-heavy routes, keep a puncture repair kit or a butyl spare on hand as backup.

Because TPU tubes are noticeably thinner than butyl, we strongly recommend inflating the tube slightly and checking it holds air before installing it inside the tyre, then seating it carefully by hand rather than using tyre levers near the tube itself. Take extra care while working the tyre bead over the rim, since pinching is the most common cause of a TPU tube failing on its first ride.

Being a lightweight, perishable consumable item that is puncture-prone by nature, this TPU tube does not carry a standard warranty, which is standard practice across the cycling industry for inner tubes in general. We recommend inspecting the tube for holding air before final installation, since improper fitting rather than a manufacturing fault is the most common cause of early failure.

TPU tubes can be patched, but they generally need TPU-specific patches or a compatible adhesive rather than a standard rubber patch kit, since ordinary butyl patches may not bond properly to the material. Carrying a spare tube alongside your patch kit is a practical option for longer rides in India where puncture-causing debris is common.

All orders including this TPU tube are prepaid at checkout, as cash on delivery is not offered on this store. Dispatch typically happens within 3 working days of order confirmation, and the total delivery timeline after that depends on your specific pin code and courier serviceability.
