I've always used 'Conti. supersonics' in my FRONT tyre for several years now. I simply became fed-up with always having to reflate a latex tube every 12 hours or so! These ultra-lightweight (50g) butyls are supple, retain the air much better, and last. I've had no problems with them (some cyclists say they blow around the valve seat) over several years of summer road cycling.. Just treat them with care & respect when you put them back in the tyre, (a procedure which is dead-easy & by hand, on my Mavic Open Pro rims and Vittoria Corsa tyres.)Report this review
Only just received and 3 x 30+ mile rides in.........no problem. Lightweight. Hoepfully it's one of those items that remain important but largely unnoticed!Report this review
Expensive but worth it as weight on the outside of a wheel matters. Weight in the center (Hub) is less critical. Need to be careful when fitting as the tubes are very thin , making them easy to pinch or twist . Bonus is these tubes take up little space in seat pack although i only carry standard spare tubes . Tubes also have removable core on valve so one can use valve extenders. I have patched one of these too and worked well .They are no more or no less puncture resistant than a standard tube. Basically the only tube i would now use.Report this review
Continental Race Supersonic Road Inner Tube - 700 x 18-25mm are great lightweight tubes. I'm unsure whether you really notice the difference, but psychologically, it gives me that edge on gradients knowing that the only thing slowing me down is my legs! I would advise, though, avoiding trying to inflate these from flat with a CO2 canister - I managed to burst one in just a second! This is probably sound advice for any inner tube though. If I have the cash spare, I will continue to buy these.Report this review
Be gentle when installing these, make sure its properly inside the tire before pumping it up. Weighs 50 gram in the short valve version, which is great, especially considered the price.Report this review
I use these tubes with Conti GP4000s tires and have not had a flat yet. I find the road feel is better than with heavier, thicker butyl tubes. Yes, you must be a little more careful when mounting the tire but worth it!Report this review
Use these for training and sportives on both the road bike and the MTB (in the 26 version). can feel the weight saving and havnt had a punture yet in 2000 miles on the Cervelo. No punctures in the mtb over the 3 years I've been using them
I think the suppleness of them actually allows them to puncture less, they deform around things
Just be careful when fitting, they wont survive the slightest pinch
So small and light you can carry 2 spares in the space a single spare would normally take
51 grams for long valve, lovely ride, similar to latex in many ways. very forgiving.
Less prone to punctures than many thicker inners as the thin rubber deforms over stuff easier instead of puncturing, but yes you do need to be careful when mounting. They remind me of the old Air-B latex tubes from the 90's (just not pink)
Use these for everyday commutes, training and racing on the cervelo (Conti GP4000s and Grand prix)and run them on my FS MTB (Panaracer cinders). In 3 years the only puncture I've had is when the rim tape failed on the MTB and the tube blew into the spike hole. (mind you I had put road tyres on it and pumped to 90 psi so wasnt suprised) Thats me doomed having said that
Another advantage is they are so small rolled up so you can carry 2 in the place of a single normal tube. Plus of course you loose nearly 100g over most other so called lightweight tubes in the most vital important place possible
For Duzza, pinch flats are caused by you not putting enought air in the tyre, they are not a function of the inner tube
I bought a batch approx. 3 years ago and all went bust within the same time after 3 years. The Butyl rubber gets old/ brittle and is prone to break/ leak where the valve stem attaches. I don't think the tube punctures any easier than others since this is more tire dependent. Only 3 stars for high price and the self disintegration after 3 years, Latex might leak but stays supple longer for the same price. One might argue if you can ride a tube for 3 years / 9000 miles it has done the job.Report this review
Very lightweight tube but extremely fragile and rather expensive, have only had them fitted for a couple of weeks and have had a pinch flat, never had one before using standard tubes. Not sure they are worth the hassle but will persevere with them for now.Report this review
