Product Customer Reviews

At least for 29 wheels it does not protect from dirt
Does exactly what it says on the box
Quick and easy to fit or remove, adjustable as required, once fitted it's solid and stable. Using on hybrid bike with 700x40 wheel and covers well with room to spare.
Excellent mudguard, easy to fix.
Does what it is intended for with the advantage if having a quick release type fitting. A good purchase.
Rear mudguard used on 4 occasions. First 3 times needed to stop to re-adjust as it kept moving and slipping down the seat post. On the 4th time using it the clip snapped so I had to bin it in the nearest bin. Spend a bit more money and get a better quality product.
I love this rear mudguard I almost use it on every bike I ride. Very easy to install and very effective as mud protection. Strongly recommend.
Fitted according to instructions, but unable to get it as tight as I would have liked and it just kept slipping down and going from side to side. Retried a couple more times, but no better. I then tried a pair of pliers to try to tighten it and broke the spring. Was then easier to get it tight, but without the spring had to tape it up to keep it in place.
I have had this a good few months but with constant adjustment due to raising and lowering seat whilst riding the hills the spring on the clip came off and I can’t fix it. Was great until then. No receipt kept so doubt I can return.
Bought for a 29er. Ironically, front and rear bought separately were cheaper than the set.
Cost effective product the mudguard is easy to fit and fully adjustable. Happy
Does the job, easy to fit.
Bought for my son's bike -fitted in a couple of minutes
Quality product-does the job keeping the mud off
Does the job, time will tell on quality but can’t complain on price.
