Vittoria Competition Latex Tube - Performance Bike Tire Tube - Lightweight Bicycle Inner Tubes for Racing

Originally I was sceptical about making the change from butyl to latex tubes but I needn't have been. People will tell you that latex tubes are fragile and puncture easily but that's all a myth. If you install them correctly they are more puncture resistant than butyl and they weigh significantly less. They key is to dust the inside of your tyre with talc, seat the tyre, inflate the tube slightly, install the tube and then fully seat the tyre. You must then ensure that the tube is not pinched under the tyre bead. Then inflate as normal and you're good to go. They ride smoother than butyl and I have not punctured yet in 3000 km. Suffice to say I'm not going back to butyl and time soon.

I've been using these for 3 or 4 months now without issue. There is a noticeably nicer comfortable feeling on the rough roads we are subjected to these days, with a nice cushioned feel to them and harsh road vibrations dampened greatly. They also save you weight over standard butyl tubes. These weigh 79g each on my scales - down from 120g each for the butyl tubes I was using.My tyres are inflated to 60psi and as others have noted they do need more regular topping up than standard tubes - every 7 to 10 days for me. I've had no flats so far.

First time user of latex tubes seem good quality, surprisingly they don’t include valve washers.

Really impressed with these, i've done about 40 miles on them since changing from standard Butyl. I had begrudgingly dropped the tubeless setup on my road bike after issues with sealing, then gone back to standard inner tubes. I really didn't like they way it felt after being used to tubeless, but these Latex tubes really do make you feel like you're back on tubeless again. Love them!

Does what it says on the tin

I have to pump each time I go on a ride but it made the poor road condition in the UK less suffering. It no longer felt like riding up-hill on flat bumpy road after installing these tubes.EDIT: the first one got a puncture after ~50km and the second one after about ~150km ride. Both got the same kind of puncture. They both sticked to the tyre and got stretched from the rotation/bump. The stretching ripped a hole.

I used standard butyl tubes before but saw that these make quite a big difference so thought I’d try them. They make your bike ride a lot nicer. They feel noticeably faster on straights but I felt like the biggest difference was cornering, I seemed to be able to corner faster with more confidence as it felt like I had more grip. They do lose air overnight so you’ll have to pump them up before every ride but not a problem for me as I don’t commute I just ride about 3 times a week.

These were great for the short time that they lasted. Installed correctly in the front and back wheel on my bike and inflated to 120 psi (fine for my 25c tyres). I went out with them in for a couple of rides and they were great. Then, whilst the bike was just stationary in the house, the front tube deflated. On examination, I found the above hole near the valve. I examined the wheel and there was nothing at the location that could have caused the puncture. The rim tape was fine and the black reinforcement on the tube would easily cover the valve hole. Thinking I was just unlucky, I ordered a replacement and went for a ride with a butyl back in the front. The next day, whilst doing some maintenance on the bike I discovered the back tube had deflated. On checking it I found a hole in the exact same place as the front. I obviously didn't fit the replacement when it came through as I don't trust these tubes at all.It's such a shame as they really did feel great to ride on.

Excelentes cámaras, muy ligeras y duraderas. Al principio pensé que se pincharían rápido pero me han sorprendido por lo bien que se sienten y por el rendimiento. Inicialmente compré solo un par pero dados los buenos resultados ya me hice de un par más como repuesto.

Yes, they'll lose air. I toured with these and found myself down 20 psi every morning of the tour. I'd pump them up to 100 psi and be down to 80 again by the next morning. With a good pump, this is not a big deal. Just plan on pumping them up every day that you ride. I don't ride often enough for that to be an ordeal, and even if I rode everyday, I'd just have my compressor ready to fill them.So why are they worth pumping up every day? They're light. I've read poly tubes are even lighter. I put them in a pair of GP5000 and they really roll. They're also reported to have low rolling resistance, maybe a couple watts lower than butyl. No flats after a couple hundred miles, even a few miles of gravel. If they keep going like this, I might stick with them over butyl -- and I just do recreational touring -- hey, why pump harder than you have to? It adds up over the long haul.Update: The front tube developed a leak at about 250 miles. There is a small crack about half a millimeter on the latex on the inner circumference of the tube. This would be against the Velox Fond de Jante rim tape, so not a puncture and not a pinch flat either. It would seem this latex is not that durable. I can patch it with another piece of latex and glue, but until I get around to it, I've put in a butyl tube -- all the LBS had in stock.

Il confort di questi camere d'aria, sopratutto in combinazione con copertoncini Conti GP5000, è superbo. Peccato che Vittoria abbia deciso si non produrle più a scapito delle camere d'aria in TPU che offrono maggiore leggerezza si, ma molto minor confort. le performance di vittoria latex + ContiGP5000 sono ancora superiori alla maggior parte di tubless... (verificate i dati)

Até ao momento têm demonstrado ser de qualidade e estou a gostar bastante do comportamento da bike com estas câmaras. Apenas lamento que não tenham outras opções de comprimento de válvula (40, 60, 80 mm) para não ter de usar extensores de válvula.Boa relação qualidade/preço.Recomendo.

Leggera, scorrevole e performante, purtroppo bisogna gonfiarla tutti i giorni perché perde pressione molto facilmente.
