A nice sturdy helmet, with easily adjustable head alignment mechanism at the back. Ideal colour for being visible on the road. Have used it many times now and is very comfortable and lightweight, just what you need from a helmet.
Racing standard Head hugger.

Just arrived in the post.If this helmet was 50grams lighter (its 300g in large), it would be used by all sportif riders. Brilliant helmet; shape is not too big, well vented. Because it's relatively slim, my rain cover fits perfectly onto it. Having a big head with a not overly big helmet means I don't look like an area 51 martian head. Despite looking trim, it fits well with the adjuster and there's enough room for a hood underneath (im size 58/59cm). Bright neon- I am definitely going to be seen.
Being a commuter-this is perfect. Being a velodrome enthusiast, I would also wear this helmet more so than my aero helmet because it fits so well. This is the best fitting helmet I have ever worn and I've tried a fair few road,pro end, and aero helmets (GIROS, UVEX LIGHT AS HELL HELMET, CASCO WARP SPRINT). It is comfortable also because of the pads, they are the most well cushioned I have seen on any helmet. This beats their cheaper helmets I have worn the last 2 years, and definitely beats the hell out of Giro helmets (weird sizing has meant I've had to wear extra large giro helmets with poor adjusters too). PLEASE MAKE A LIGHTER RACING VERSION, many racers would buy.
Everything!!!!
weight- being nit picky!
Saved my life
The best test of a helmet is to crash while wearing it. I did that, not on purpose of course, and the helmet did its job.
After hitting the deck in a 30+mph i whacked my head off the ground. My helmet broke taking the impact and i walked away with nothing but road rash.
I plan on buying another, it looks pretty good too! Thanks btwin!

The strap adjustment could be better. The under ear clasps move too easiy and the strap just won't stay tight, However for £27 its a decent enough lid.
Low cost and reasonably stylish
Strap seems to loosen every ride.
Great Bike Helmet
Used for More than 1 year
Great helmet at a fantastic price. I use it for cycling to work but have also done several sportive including the Tour Of Cambridge and it's comfortable for long rides as well.
Combines well with the B'TWIN VIOO CLIP 300 LED light that clips onto the rear head band for added viability at night.
Comfortable, Stylish & good protection
Commuter
Used for 7 to 12 months
Thumb wheel is the way. One hand action, even wearing gloves.
To adjust this sliding thing you need to stop and use both hands.
It could be a great lid! Shame.
Light, not mushroom type of helmet, good ventilati
Rear adjuster? TERRIBLE, TERRIBLE
Snazy

Decided to update my cycle helmet as the previous one bought from Decathlon was getting old & was actually for mountain biking; whereas I mostly cycle on the road commuting.
Having looked around at the options this seemed a decent helmet at a good price. Plus it didn't have a visor & because it is white think it stands out from the crowd. Useful on the busy London streets commuting.
Lightweight, bright
Keeping it clean
