This tube fits road clincher tyres in the 18-32C range, covering narrow race tyres through to wider all-road rubber. It comes with a 60mm valve, sized for shallow to mid-depth rims — if you're running deep-section aero wheels, check the valve reaches through and out the far side before buying, since Cyclami also offers an 80mm valve version of this same tube for deeper rims.

Cyclami offers this TPU road tube in two weight tiers. This 38g version is the sturdier of the two, giving you most of the weight saving of TPU while keeping a slightly thicker wall for everyday durability, making it a sensible pick as your main tube rather than a race-day-only swap. The 30g tier trims a further 8g by going even thinner, which is great for racing or as an ultralight spare, though honestly it gives up a little of that extra margin on rough roads.

A metal valve stem is generally more rigid and heat-resistant than a plastic one, so it holds up better to repeated pumping, valve extenders and the vibration of rough roads over time. Cyclami also sells a plastic-valve version of this same 38g tube at a slightly lower price if you'd rather prioritise every last gram over long-term valve durability.

TPU tubes need a TPU-specific patch — a standard rubber patch kit won't bond to the material and will peel off within a few kilometres. Cyclami's own glueless TPU Patches Kit is made exactly for this: clean the area with the included alcohol pad, press on a patch, and you're back rolling in under two minutes. It's worth carrying one alongside this tube on every ride.

TPU tubes tend to lose a little more air between rides than butyl, so it's worth topping up before you head out rather than assuming last week's pressure is still good. Beyond that they're used the same way as any clincher tube — inflate to your usual road pressure with a Presta-compatible pump, and check occasionally for slow seepage, which is normal for the material.
