Excellent Value

This has got great venting, looks aero and more expensive than it is. Padding is comfortable. Only one very slight niggle, the strap can be difficult to adjust properly, but not impossible. The size came up a little small for me so I would double check sizing before ordering. Overall I would highly recommend this helmet. Great work Decathlon! Cheers.


I find these really comfortable.

Van Rysel Road Cycling Helmet

This helmet did its job when I came off my bike and my head slammed into the kerb. There was a significant dent in the helmet, but I was unharmed apart from a few aches and pains for a few days afterwards. Replaced the helmet with the same one as I know I can trust it - but I don't recommend testing it like I did!!

Van Rysel Road Cycling Helmet

I only had the helmet about 1 month before it was tested in an accident. When I came off the bike, my head slammed against the kerb. There was a significant dent in the helmet, but my head was still intact. The helmet did what it was designed to do, and probably saved my life. It will be replaced with another, identical helmet as I am happy with the way it performed.


The items I bought were Very good quality but having problems at the till very slow

Not a great fit

It fits more like a child's helmet. Had to return and bought a much better fitting giro helmet.

Careful on sizing

So I took all the sizing comments on here with a pinch of salt as in my experience usually, this is people who cannot measure their heads properly. My head is 58cm this puts bang in the middle of the stated large sizing. I very nearly ordered online but when I realised the delivery times were so long and I noticed the large helmet I wanted was in stock in a local decathlon I decided to buy in person, I am glad I did! The large size helmet on my 58 cm head did fit but it was perched more on top of my head than around it so there was no protection to my forehead area at all and whilst some cyclists seem to think wearing a helmet on the back of your head exposing your forehead is correct, it is not! same as a helmet is too small, a helmet is supposed to cover as much area as possible both at the front and the rear of your skull. Luckily there was an xl helmet in the store and this fitted almost perfectly although as other people of said the helmet does seem to have a very round profile so there are slight gaps on the sides but for me, it was close enough. This XL helmet is allegedly for 59 - 62 cm this is total nonsense, I highly recommend you try this helmet on before you buy, visit a store if you can do so. On the positive side for £40 this seems to be a very well constructed, quality, not bad looking helmet on par with the big brands at a fraction of the price, as people have said there is some moaning about no being able to adjust the straps in the "triangle" or ear area, in my opinion, this is nonsense if you are wearing the helmet properly i.e. on your head covering the forehead area and not on the back of your head like a goon this area won't need adjusting in 99% of all cases. would be a 5-star helmet if decathlon actually did something about the sizing, it's not like no one has told them the last couple of years or so!

Great fit.

This helmet lives up to the description, it fits well, its comfy and very light given me full confidence in the product.

We have designed the helmet's inner ventilation to maximize thermal regulation of the head using the "jet" effect generated by air inflows through the grille, 16 inner channels, and extractor.

In-mold molding technology and eps

The In-Mold molding technology used in manufacturing this helmet makes it possible to mold the external polycarbonate shell during the expansible polystyrene (EPS) injection stage. This results in a structure that is much stiffer, very durable, and extremely light. The inner EPS structure absorbs the energy generated during an impact so that it is not transmitted to the skull, while the stiff external shell provides the helmet with longer-lasting durability.



Storage instructions

Keep away from UV rays (direct sunlight exposure) to avoid premature deterioration of the helmet. Do not expose to high temperatures (140°F max.); store in a dry place.
