Bought from service champions and can confirm that they are genuine. Quality is excellent, much thicker than the last one I used (Tesco brand) which didn't last long. Do quite a bit of off-roading these have done 20 mile punishing ride in the last couple of weeks, absolutely no loss of pressure.
It's an inner tube, what more is there to say. Arrived boxed as shown in the product description, I noticed some other reviews reported it being delivered out of box, probably depends what size or seller you order from.
Ordered via the Amazon Add-On program. Seems to be of good quality, been using my 26x1.5 on an old mountain bike I use for short journeys.
Selected this one as a known brand (Raleigh) rather than a manufacturer I didn't recognise.
Honestly, I don't know how they can sell these for £2, including postage (albeit with Amazon Prime or if spending more than £20 otherwise). Great value, great quality, works perfectly. No complaints! Will be buying more of these in future.
