Full-9 Helmet

Bell's Full-9 helmet packages all of their engineers' expertise from motosports into a bike-specific helmet. They also gathered a year's worth of feedback from professional downhill riders to make this their flagship bike helmet. Ready to take on anything you find on your mountain or BMX bike, the Full-9 is one of the best full-face helmets money can buy.

Bell's engineers built the Full-9 with a unidirectional full carbon shell. This makes for a highly durable and incredibly lightweight helmet that doesn't weigh you down like other full-face helmets. The Overbrow Ventilation system uses 10 vents to actively channel air over your head from the front to back to keep you cool as you ride.

Bell packed the Full-9 with features to keep you safe and to enhance your overall riding experience. If you are injured, you can use Bell's Integrated Eject system, which allows safe removal of the helmet due to a recess in the EPS that allows the cheek pads to quickly slide out. And the helmet's removable, 360-degree breakaway camera mount allows your camera to pop off when you fall in any direction, protecting your neck, camera, and the helmet itself.

To make your ride more enjoyable, Bell added Soundtrax built-in speaker pockets and cable routing out the back of the helmet so you can pump tunes without getting tangled up. The helmet weighs around 1130 grams and is certified to CPSC; ASTM BMX, Downhill, and CE standards. Finishing touches include a padded chin strap with a D-ring closure, a fully-adjustable Flying Bridge visor, and removable magnetic cheekpads.

Everything you want in a full face

I've used it several times

It's light, it's tough and it's pretty well ventilated. Haven't really used it yet and hopefully I won't have to. Fit is true to size. The detachable cheek pads are top notch quality, they stay put when you want them to yet remove fairly easily. My only real complaint is that the visor doesn't come down as low as I'd like and as such doesn't block as much sun from my eyes as I'd like. Other than that, it's perfect. Oh and that carbon fiber shell looks pretty sharp in the sun!

I went through through all the big hitters (Fox, TLD, POC, 100% and Giro) flagship helmets. I couldn't find one that fit me well. Called up the nice dudes at Competitive Cyclist and was recommended the Bell Full 9 after sharing my frustration. Couldn't be happier! I took this thing out on its maiden voyage to Angel Fire NM and had a blast. The helmet is super comfy, breathable and makes me look way cooler than I actually am.

The Bell Full-9 is my helmet of choice when riding big lines. Comfortable, breathable & lightweight, perfect for long days on the hill getting gnarly AF

Love it.

I've put it through the wringer

I love this helmet. I have owned Giro Cipher helmets for years and really have enjoyed those and for the price I think they are the best helmet out. However, if you 're willing to spend an extra $100 or so I think that this helmet is well worth it. It is lighter than the cipher and the matte black color looks super sleek. It vents very well and I often forget that I'm wearing it. 5 stars all around.


Are there speakers included for the speaker pockets?
