Fits my bike and good value.

Fits my bike with slight adjustment to not interfere with the V brake.

Needs care when fitting.

Instructions weren’t too clear for fitting, and the first attempt resulted in them coming loose and eventually coming away completely. Had to use a lot of strength to get them slotted in securely, and without any screw fittings am always worried they may come away again if caught by my knee. Apart from that, they are neat and work well.

MTB front mudguard.

Works well, easy to fit and very reasonable price.

Bought for a 29er. Ironically, front and rear bought separately were cheaper than as a set.

Would these fit the Rock Rider 520?

would this mud guard fit the Rock Rider 520 bike?

Did not fit

The fitting would not fit my shocks. The large was too large to go in, the small too small. Used fittings from the old mudguard and now all ok

Thank you for taking the time to give us your review. Apologies for the bad experience you have had with the mtb mudguard. The front mudguard for mtb is  installed from the bottom or the stem. This clamp cannot be adjustable because it holds together the mud flaps. The mud flaps can however be detached when not needed. Do let me know where else you are looking for an adjustment and we will try to get it incorporated. Also you can visit the closest Decathlon store and explain the concern and we will be happy to find a solution for you. 

Removable flaps are good.

The mudguard has removable flaps. I put it on only when I ride in the rain since I like the way my MTB looks without the flaps.

Decent product

Don't expect it to help you end the ride spotless. But does it's job.

Guards from eating dirt

Does not completely eliminate from every single drop of mud not being splashed. But guards to a certain extent.

Bad Quality Mudguard

The Front mudguard groove fixed to metal insert broke easily . The Groove is bad engineering

Hello Prashant,  

Thank you for taking the time to give us your review. Please note that the mudguard hinged are designed to be removable and is made of flexible plastic. It can only break on hard impact. I suggest you visit the closest Decathlon store to check if you can get a replacement.  

Mudguard is not fixed tightly.

Mudguard is not fixed tightly. we could remove it easily, need to fix it tightly.

Hello Joshi, 

Thank you for taking the time to give us your review. The mudguard works well for MTB conditions. The flaps can be removed when you are not practicing MTB. Please let us know where we can improve on the quality of the mudguard and we will help give better feedback to our product engineers.
