    Inner tubes

    Great value compared to bike shops

    Not the best valve fit

    After fitting the inner tube, replacing the tyre and starting to ride again, a noise started to emit from my front wheel which was not present before changing the tube. Every time I rode over the slightest surface bump the noise would happen. On closer inspection the issue was that the valve was too skinny for the opening on the wheel rim so was moving around and hitting the rim over every little bump. This could be solved with a threaded valve rather than the smooth finish to tighten the valve to the rim and mitigate the issue. Aside from that function seems fine. I replaced as soon as i got home as I couldn't live with the noise.

    Thanks for your review. The valve is particularly long and better suited to deep sectioned rims. If your rims are shallow and the hole is wider than 6.5mm then there may be a risk of some noise but it is the first feedback of this nature we've had with this item.
    I guess that a 48mm valve may be a better bet.
    Either way, if you're noisy then please feel free to return them to us and we will gladly exchange them for you as I can empathise with you relating to persistent and annoying sounds when road cycling.

    700x18/25 Inner Tube - 80 mm Presta Valve

    I have had no problems with this tube at all. The only comment I would make is that I asked a member of the cycling team to advise which tube I needed for the bike I had just purchased. I was advised on this tube with an 80mm valve. On reflection, I clearly didn't need a valve of this length but its not a problem.

    Terrible - 4flats in 2 rides!!

    Currently used 4 inner tubes all of which have failed, 2 within 5 minutes of starting rides, the others have lasted 10 and 30 miles - newish tyres checked for debris and nothing. Will not be buying again and would certainly not recommend. Similar prices tubes available of a much higher quality

    5/25/2017
    I'm sorry to read that you had so many punctures within such a short space of time. As a fellow road cyclist I can really empathise.
    There are so many factors which can cause punctures that it is hard to tell sometimes what seems to be the root cause but what is certain is that an object of some sort is penetrating through and piercing or pinching the tube. It may be worth checking the rim tape again or having a closer inspection inside the tyre to double check and make sure that a very small (and hard to spot) object is not causing the issue which may be embedded in the tyre.
    If of course you're not confident with the remaining innertubes, then please do not hesitate to return them to us for a refund.

    Inner tubes

    Not the lighteset but they do the job very well

    Retains pressure but .............

    The lack of a thread on the valve stem means that on the road your average pump has nothing to screw onto, and unless you have a clamp mechanism, these inner tubes can be difficult to inflate sufficiently. Otherwise they are very good, but I probably won't buy again

    Great!!

    My Husband love them

    Excellent long value tubes

    Bought these for my 50mm deep Campag Carbon rims, fit perfectly with plenty of valve exposed to enable ease of inflating. Despite there being no screw clamp to secure in the rim there is no rattle, could be different with other rims though! Much cheaper than other alternatives and works fine!

    Great value

    Would like to see a wedge to slide down the valve to stop rattle.

    Tube gets burst on rim facing surface

    We are getting frequent puncture, almost to the predictability of 50%, got my 500 model serviced on 8th Nov when they put in a new tube that did complete a 200Km ride next day, but in next 2 days got puncture facing inner side of tube facing the rim, I called them that this is a defect by manufacturing and there were a line of blisters facing the rim. They called me with the wheel, replaced the tube. A month later on the new tube, got a burst next to valve, again facing the rim, following week same issue with my Triban 100 front wheels. I use your own pump and put the recommended pressure.

    Hello Pankaj

    Thank you for taking the time out to review our product. We apologise for the bad experience you faced with our product. please check if the inner liner which placed inside the rim to cover the spoke holes are in good condition? and if there is any cut or anything on it, 
    Inform the same to our technician and get the rim tape changed and see if there is any change that you notice.
    Do let us know your feedback, 

    Thank you

    very poor quality valve , get distorted and broken

    the presta valve in the inner tube is very bad quality, while pumping air using a hand pump (Btwin 500hp), the valve bents and leaks out entire air. The valve which came with the Triban 100 bicycle got broken while filling air, I went Decathlon and purchased a new inner tube, again same thing...its the way this valve is constructed, very delicate and totally useless...

    Hello Pujan
    Thank you for taking the time out to give your valuable feedback. we will inform our product manager regarding the delicate Valve construction, in the meantime, if you facing the same issue again please take the defective tube back to the stores, and you will be given a new tube as a replacement.

    Thank you

    Size issue

    My requirement was 22* 28 tube as tube doesn’t get thin over the period. And now riders are shofted from 23*700 size to 25*700size tyre. I did not get option in Decathlon so ordered 18*25 tube . I hope Decathlon will make it available for future with 80mm clincher.

    80mm tube @ cheap rate

    These tubes are durable and offer excellent value for money @ Rs 199. You can not find 80mm tubes at such price point. If you are facing issues then you have not installed it properly. always inflate the tube as instructed before installing it.
