Not that great

Added these to my bike and on it's first ride at just below the tyres recommended psi did a small jump and when I landed it had a rear blow out and threw me off. Wasn't happy at all, luckily rims were not damaged, but could have been costly.

Thank you for taking the time to review these innertubes. Whilst they are effective at preventing small thorns and the like from leading to a puncture, they offer little protection against tyre pinching. We always recommend you follow the tyre pressure recommendations as stipulated by your tyre manufacturer. Looking at going down the tubelss route may be a more sensible option as this set up is particularly suited to preventing pinch flats.

Valve

I bought the inner tube but was a bit disappointed had when I got home I didn't have the correct fitting on the pump to inflate the tyre.

Patch it

Already bought one of these when fitting a new tyre to my partners bike, bought a second to fit when the requested tyre is in stock. First time tried these but you don't know until you try them, so far no problems with the first one I fitted, despite a couple hundred miles so far on thorn covered tracks, I think the ungraded tyre helps to.

Highly recommended tube.

I've had these tubes in for around 4 months now, had no trouble fitting and haven't noticed the extra weight as some people suggested I would. I am really enjoying going out with the club and not being the one with the punctures. I'm out several times a week over some rough terrain and I know there are several thorns that have gone in them but they are still fully inflated so very happy. Some say the downfall of these tube are that if they deflate and you need to repair you will probably find several punctures and you would have to repair them all before re inflating. My answer to this, if I found the tube had multiple punctures that needed repairing, for the sake of £3.99 I would just replace with a new one. If every set lasts over 4 months I'm more than happy with that.

Todo perfecto

Muy buena calidad

NO ME GUSTA

La válvula es demasiado larga y además no lleva rosca en la parte inferior ni tuerca para q la válvula se ajuste a la llanta. La coloque y a los 4 días ha bajado la presión considerablemente. No lo recomiendo.

Pinchada el primer día

Primer día que salgo con ella se pincha con un clavo muy fino. No se ha tapado el pinchazo con el líquido. Poco recomendable. Además, válvula muy fina que baila en el agujero de la llanta.

Buena compra.

Válida para pequeños pinchazos.

Muy buenas

Tan en pinchar

Regular

No lleva seguro cuando lo montas en la rueda y cuando quieres hincharle se mete la válvula y pierdes tiempo.

No va bien

Compré dos recámaras y solo he utilizado una porque al montar una hay que darle mucha presión como si la boquilla estuviera obstruida así que devolví la otra

Additional Product Information

Composition

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 27.5 x 2.00 means a tire with a 27.5-inch diameter that is 2.00 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means that the tire is 50 mm wide with a 584 mm internal diameter (approx. 27 x 2.00).

Removing an inner tube

Remove the old inner tube using B'Twin tire levers.

Checks to carry out before installing an inner tube

Check the condition of your tire and replace it if necessary. Make sure no objects are lodged in the tire. Check the condition of your tire rim strip. A rim strip that is even slightly bent can cause punctures. Check that your rim does not have any other issues that could damage your inner tube

Mounting the inner tube

Watch our video before you start. Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rim. Put the inner tube entirely inside the tire so that it fits inside the rim. Take care not to pinch the inner tube when fitting.

Mounting the tire

Start by mounting the tire onto the wheel on the opposite side to the valve. Finish mounting the tire at the valve to avoid pinching the inner tube. Never mount your tire with a screwdriver or a tire lever, as you risk pinching and puncturing the inner tube.

Inflating the tire

Inflate your tire carefully, to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tire is in the correct position as you inflate it.

Tip from the pros

To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tire before each ride.
