I had this helmet for a little over a year. I was going too fast for the wet road conditions, down a medium grade. There was a slick area at the bottom from the previous night's rain. I was almost across and coasting at 15-20 mph when my front wheel lost traction and I went down, very hard, and very fast. I sustained significant road rash on my shoulder, arm and leg. I needed stitches in my hand where my knuckles rubbed through my gloves. Bottom line I hit my head very hard also. My Bell sustained significant damage but it really saved my head. No LOC, No HA. This is a top quality product that really delivers.
Besides the above, I can add that I appreciate the fit. Even in Florida rare occasions require a liner and the adjustments are good to accommodate different thicknesses. Looks good too, lots of ventilation.
I had a tough time picking a helmet mainly because I hate sending things back, i have a fairly large oval head 7 58th and of course it had to fit comfortably (I sent back a size large Kask that was really built for a round head shape that did not come close to even getting on my head let alone fitting) The Bell Z20 fits beautifully, and after about 800 miles of use it is by far the best choice I could have made, I never even know it is on my head while riding. As a bonus it fits pretty low profile compared to my other helmets so the light bulb head effect is very minimum.. Perfect for me and I hope I never have to find out what MIPS is..
Ive always preferred the fit of Bell over all others with my more oval-shaped head. This one is no exception. A new nice touch on the Z20 is a thin rubber edge on the rear cradle to further reduce the risk of any pressure points. Great fit. Great looks. And a great deal on sale. Done.
I wanted a MIPS helmet, and researched several before choosing the Z20. It was not the cheapest, but I knew Bell to be a quality product. And it came in blue to match the accents on my bike. I was quite happy with the fit of this helmet and the adjustments possible make this the most comfortable helmet Ive ever worn. Ive not worn it through the summer heat, so cant comment on ventilation, but so far Im a big fan. I hope I never have to test its MIPS capabilities, but I feel more confident knowing that is part of the design of this helmet.
I purchased the helmet a little over a week ago and only have a handful of rides under it. So far it has been brilliant. The fit is great if you have a Bell shaped head (more narrow than round). The ventilation is superb, and I really love the padding that is designed to deflect your sweat from dripping into your eyes, it has really been working well during the few hot temperature rides. One thing that I will point out is the strap length. A tad too long. I ended up trimming a bit of the excess to prevent it from flapping around in the wind. Overall a fantastic lid!
This is a good looking, non-aero helmet. It seems very well constructed and nicely finished. A bit heavier of a helmet than what I am used too, but also my first with MIPS. Ventilation is good. On my first couple of rides with this helmet I was over-tightening the adjustment wheel thinking it was secured down well enough. This was leading to hot-spots and headaches. Finally figured out that it doesn't need to be as tight as other helmets I'm used to and will still be securely fastened.
I use it primarily on training rides when weight and aero qualities aren't important. When racing I opt for a lighter and more aero lid.
