This tube fits gravel clincher tyres in the 32 to 47C range, covering everything from fast gravel race tyres to wider adventure rubber. It's available with either a plastic or metal valve, and in two valve lengths — 45mm and 65mm — so check your rim depth before ordering to make sure the valve stem reaches through and out the far side comfortably.

A metal valve stem is generally more rigid and heat-resistant, holding up better to repeated pumping and valve extenders over time, which suits riders who inflate often or use deep-section gravel wheels. The plastic valve version shaves off a few extra grams and costs a little less, making it a fine choice if you're prioritising weight over long-term valve durability.

Gravel riding in India often means washboard tracks, loose stones and the occasional pothole-riddled stretch of tarmac, and this tube's 46g TPU construction is built with exactly that kind of abuse in mind. It won't make your tyre indestructible, but it seals small punctures better than butyl and holds up well to the vibration and impacts of longer unpaved rides.

TPU tubes require a TPU-specific patch — standard rubber patches don't bond to the material and will peel off quickly. Cyclami's glueless TPU Patches Kit is made for this exact situation: wipe the area clean with the included alcohol pad, press on a patch, and you're back rolling in under two minutes, making it worth carrying alongside this tube on any gravel ride.

TPU tubes lose air a little faster between rides than butyl, so top up pressure before you head out rather than assuming last week's fill is still good. Beyond that, use it like any gravel clincher tube — inflate with a Presta-compatible pump to your usual gravel pressure and expect occasional slow seepage, which is normal for the material.
