These inner tubes are light and work well, I`ve had no punctures as yet and I`ve done over 100 miles so all good as yet, I would recommend this product to anyone who wants a light inner tube with good puncture proof properties, and also I don`t have any problems with them losing pressure like some people have stated, I just pump them up to pressure once every 3 days usually ten strokes with my bike pump and they`re ready to go
Quite light for their puncture resistance, price is reasonable too
Much lighter then standard Michelin butyl tubes.
Have not been using them long but feel great to ride on.
You do have to pump them up almost every day but its a small price to pay.
Usual excellent service from merlin as well
just started using these and they seem pretty good much lighter than standard tubes and are less likely to pinch flat only problem is they loose a couple of psi a day.
Nice and light, but only slightly lighter than the butyl tubes I took off. Haven't used them long enough to comment on puncture resistance. Have had them long enough to say that you need to pump them up before every ride though!
I've tried various types of butyl, I've tried 2 types of slime and had problems with all of them. Latex tubes just work. Threw an old one away last week after the valve failed - I'd had it about 7 years and it had no patches on it...
