This tube is built for 1.9 to 2.5 inch MTB tyres and is offered in versions sized for both 27.5 inch and 29 inch wheels, so make sure you pick the variant matching your wheel size rather than just your tyre width. Using the correct wheel-size version keeps the tube properly seated without excess folded material bunching inside the tyre.

The 65g weight is specifically tuned for trail and XC use rather than being a stripped-down race-only tube — it's thicker than Cyclami's road and gravel tubes because MTB tyres see harder impacts from rocks, roots and drops. Riders doing everything from casual singletrack to more aggressive trail riding use this tube as their everyday choice, not just for race day.

This tube comes with a plastic Presta valve, which keeps overall weight down and works fine with standard MTB rim depths. If your rims are unusually deep or you use a valve extender regularly, it's worth checking valve length before ordering, since plastic valve stems aren't extendable the way some metal ones are.

TPU tubes need a TPU-specific patch — ordinary rubber patch kits won't bond properly and will lift off within a few kilometres. Cyclami's own glueless TPU Patches Kit is designed for exactly this: clean the puncture with the included alcohol pad, press on a patch, and you're rolling again in under two minutes without waiting for glue to cure.

TPU tubes tend to lose a touch more air between rides than butyl, so it's worth topping up pressure before you head out rather than trusting last week's fill. Otherwise it's used exactly like any MTB clincher tube — inflate to your usual trail pressure with a Presta-compatible pump and check occasionally for slow seepage, which is normal for the material.
