It keeps the mud of me!

They do the job, but fitting the front is tricky, and the rear needs frequent adjustment.

Rockrider Mountain Bike Mudguard Set

Fitting the rear was simple enough but the front proved to be more difficult. There are two different fitting supplied for the front mudguard but both proved to be of no use. These fittings were either to small or to large to fit the mounting point on the MTB. Instruction supplied were basic and could do more additional fitting information. In the end, I opted to manufacture my own mounting point for the front which was simpler and a lot easier to fit.

Not suitable for 26" wheels

The grommets to fit the front mudguard into the front forks were the wrong size - I had to use some old inner tube to make it fit. The back mudguard falls off so often I am going to have to buy something else. Would not recommend.

Fits a treat

Fits the bike perfectly.

I purchased a Decathlon mountain bike at Christmas and then ordered the corresponding mud guards. The rear one moves around a lot due to poor frame fitting and the front one just doesn't fit and dropped out when riding - which could have been nasty. Waste of time and money - not cheap either. Has put me off Decthlon.

Fiddly to fit, keeps moving position, right annoying it is! However when it stays where it belongs it does block a lot of muck n debris. I thought it was a little expensive to be honest, it's only a couple of bits of plastic after all.

Don't buy

Do not buy This product is rubbish and doesn't stay where its ment too

Poor quality - broke on 2nd ride out

This is the first decathlon product which for me has been sub-standard. 2nd ride out the rear mud guard clip failed and broke off completely. Really disappointed, as I had to bin it whilst on my ride out as I had no way of carrying it back half way through my ride - so now wont be able to claim a refund. Given the price, I was hoping for much better quality. Usually I am very happy with Decathlon own products.


I’m 13 and went to school on my bike today with my new mud guards. I went down a kerb and both front mud guards fell off . When I was coming home I went down a kerb and the back fell off and it is broke and will not come back on. The front mudguards are awful and I don’t recommend buying

Poor build quality, doesn't stay in place for long

Front mud guard is ok, could be slightly wider to actually deflect water when cycling through, but ok and stays in place at least. The back is entirely made of plastic, and the ratcheting attachment doesn't stay in place so rotates out of alignment leaving it useless.

Very good
