Vittoria Competition Latex Presta Valve Tube

I'm writing this review because I've had a different experience than the others here. Maybe this is a bad batch/good batch situation (I purchased it in late 2022). Anyways, these have been stellar tubes. To start with, yes, they do slowly leak air. However, this is a characteristic of latex inner tubes, which you must consider if you decide to run them. This is no different than maintaining a tubeless setup, where you must add air before each ride.Yes, they are faster than butyl tubes. There is a lot of research online about this subject, and the general consensus is that latex with high-performance tires is roughly the same efficiency-wise as tubeless. I personally prefer latex because I'm not too fond of the mess, and have found clincher tires far easier to ... MoreI'm writing this review because I've had a different experience than the others here.

I personally prefer latex because I'm not too fond of the mess, and have found clincher tires far easier to mount. There's no way I could ever go back to butyl: the difference in rolling resistance is pretty apparent.

I use these with Bontrager Aeolus wheels that are 38mm in depth. Valves fit and allow extra room without the need for extensions.I've never puncture popped one, but have popped a couple via carelessness. They allow for an incredible ride feel when set at the right pressure. Best thing next to tubeless.Air loss on latex tubes is normal, I generally pump them up every other ride, if not every ride.

I heard a lot that these chambers do not hold pressure well.However, the reality turned out to be different.On the recommendation of the tire manufacturer, I pump 7.5 bar rear wheel and 7.0 bar front. 24 hours after installation, the pressure dropped by 0.5 bar / And this is comparable to the butyl chambers that I used before.As for performance, I rely on the opinions and results of more accurate and continuous research conducted by experts.
