Mr Lao These are awesome! so light and easy to put in your back jersey pockets cause of its small compact size
Mr Cohen They arrived on time. They are great tubes. What else can be said about tubes?
John Have always used Continental light tubes, seems to improve rolling resistance, at 95kg I need all the help I can get
Alberto After blowing a few supersonic ones while trying to mounting them, these work pretty good. 87g on my scales for a 6mm length valve. I have saved a few grams with these, it all counts!
Luckyhawten Light and durable. Highly recommended!
Mr Crawford Good tubes. Value for money and one of the few available with a long enough valve for my Zipp 404's
Mr Oakes Great spare tube. Heavier than the supersonic but a bit more durable.
Francis I'm an advocate to continental products. Lightweight and does it's job well. Big thumbs up
Lucas These are great inner tubes. Light without being flimsy and at a good price point on Merlin!
Mr Hunt Good quality tubes, only ones I know that have the removable valve, used them before with no issues.
Mr Goh Correct size and serves purpose. However, metal shaft does not come with entire spiral screw threading and screw. Hence shaft may wobble on the move. Solution is to use a bit of electrical tape around shaft to secure position in contact with the rim.
Christopher Good quality lightweight tubes at a great price
Stephen Lighter than the usual tube, require more frequent pressure checks.
Daniel Go to tubes - always reliable
b.champ Very light. Quite fragile. Do not use as a spare tube.
stephen This is a lightweight tube that has a small volume when rolled up and fits in easily to small saddle bag. Ive only used one so far but found it worked as well as anything else on the market and at a lower weight and size. I have just bought the even lighter Supersonic tube to try but haven't had a chance yet. I am careful putting on tubes and mostly have been using Specialized Turbo lightweight tubes but these are more expensive and a bit bigger to carry in a pocket or saddlebag. If you fit a tube with a small amount of air in it without twisting it or pinching it and put in well into the rim and take your time (as you should with all tubes) then you have a perfect fit. All lightweight tubes will need their air pressure checked a little more than thick, heavy tubes but they don't lose air anywhere near as much as Latex tubes.
Erwin As usual service delivery is always excellent. Product quality is 5 star. Very light inner tube perfect for my Conti GP4KS
Mr Crittenden I could definitely notice a difference between the light and regular. These are really easy to damage, but worth it.
Mr Ramirez Rayos Continental inner tube is one of the best inner tube in the market.
Mrs Stislow This is the only tube I trust. Excellent product and excellent service from Merlin. I'll be back for more!
Mr Kenc I bought these to replace my stock inner tubes which were large tubes designed for 25-32c tyres and they were 125g each. These light tubes came exactly 80g as claimed, so I saved 45g of rotational weight from each wheel. It was easily noticeable in the first ride (could be the lowered rolling resistance also). It has been about 700km now and never experienced a puncture. I used them with 25c GP4000S II tyres and inflate them to 110/120 psi. Our roads are far from smooth either. So far so good!
Koji Lighter with no higher risk of flats. Worth little more investment.
Mr Calabrese A good, high-quality, lightweight tube.
Mr Achten Used Continental tubes now for a while, no problems highly recommend.
gMoney Great value. Conti tubes have always been my choice for a quality product that you can rely on.
Lucas Solid tubes, the extra money seems worth the weight savings.
sPATZ Been using these for a while with no more or less flats than with standard tubes. You do save about 1oz./wheel.
Mr Bartlett Super light, makes it easy to carry a couple with no issues on longer rides. No punctures as yet.
Zadeh Very light tubes. Will make a huge difference in performance.
Mr Atkinson Bought to go into GP 4 seasons. Light and durable.
Mr N My favorite tube... light and Conti... nothing else to say.
Mr Rothwell Lightweight good quality inner-tube with valves that are the perfect length for 50mm deep section rims. A much better alternative to valve extensions
Joe W A very good tube in my opinion, a good compromise, light enough to notice a difference but not too thin and decent puncture resistance. Merlin as always fantastic service and delivery, now my favoured site to order through for cycle bits if possible.
Tinman Lightweight, durable tubes.
Mr Newman Very light and occupies little space in my spares kit. Holds pressure well.
JustAddLightness Light and leak-free. Pack down nice and small. What more could you need?!
Bikeboy29 Wanted to reduce my bike's overall weight, which meant new wheels and tyres and thought I'd go the whole hog with new inners. Only used once, on a 70 mile jaunt on potholed London and Essex roads. No problems and didn't lose much (if any) air pressure.
Peter C I purchased a relatively narrow wheel with a 42mm carbon rim and soon realised it wasn't easy to get a quality tube, presta with a 60mm valve to fit. The Conti tube has ticked each of these boxes and has ridden really well.
Mr Cleary Great tubes, never a problem with them so I keep buying them
Mr Evans Noticeably lighter than the standard Race. Don't lose air too badly either. Haven't had a puncture since putting them in. Like fact that same weight as a narrower tube, but suit my 25mm Contis.
Mr Roberts Nice and light weight but hold pressure well
Mr McBride Really pleased with these, so much lighter and thinner than the standard conti tubes. Over 300 miles so far with my new Gatorskins also from Merlin and no p f visits yet, and great service from Merlin as always.
Tommy Gunn Can definitely feel that this tube is lighter than regular tubes.
Mr Greatrex Nice light tubes, don't lose pressure too quickly at high pressures like some tubes can.
Mr Large What can you say about inner tubes. They either work or they don't. The only additional thing I can say about these inner tubes is that the extra long vale means that you don't have to use valve extenders when using deep rimed wheels.
Mr Baker Much lighter and better tubes than the ones I used before. I will definitely use these in the future. Great service by Merlin as usual.
Mr Nayler I've just bought a beaut set of light wheels for racing so why put anything but light tubes on them. As part of a lightweight combo its a no brainer.
Mr Hsu Its Continental, its good. Merlin deliver the item promptly to Hong Kong, arrive in under a week
David Great lightweight tubes, no puncture issues and a good weight saving over standard version. Great combination with the Continental GP4000s tyres.
Brad Great tube, I always use them.
RickyM Great inner tubes. My preferred choice.
Mr Cook Nice and light
Mr Barta Very light and strong.
Mr Barta Very light and durable!
Happy cyclist Good light tube, shorter 42mm stem length fine with non aero wheels, another good buy, will be ordering some spares too.
Mr gormley Do the job well
Mr Andrews Good light tubes which seem to hold pressure well. Only ridden 20 odd miles on them so far, but no problems. Bit expensive but still the best and cheapest way to remove meaningful weight from your ride
Dr Mason As described. Best price on the web.
Mr Smith
Mike Good reliable tube.
Mr bilton Always good to have a spare tube you just never know if you or a mate is going to get a flat.
Mr Gore Solid tubes. No complaints.
