I own the Z20 and now the Stratus. The Z20 is a superior helmet but the Stratus is still a good helmet. I purchased the Stratus for foul weather gravel riding. The helmet fits my rounded forehead well. The straps were an ample length. I saw reviews that said the straps were too short. The fit adjustment dial is easy to use. I'm able to comfortably wear a skull cap and a hooded baselayer underneath the helmet. My two biggest issues with the helmet are 1) the vents aren't spaced to hold sunglasses securely and 2) the helmet is somewhat bulbous and not streamlined. Even with these two issues I still like the Stratus a lot. It is reasonably priced mid range helmet.
First, BTD did a great job filling the order and shipping the product as ordered. The product itself has some issues. The chin strap is too short. I wear a skull cap and the adjustable end of the strap just clears the buckle with no excess to fit in the keeper. I contacted Bell and their response was that I was not wearing the helmet properly. I have been riding bikes for 60 years and 40 of them have been with a helmet without exception. I know how to wear a helmet. When winter comes I plan to wear a heavier head covering, which will not work with the strap as currently configured. I am looking for an extender to resolve that issue. The second issue is that the MIPS fit is different than the predecessor design. The helmet needs to sit somewhat back on the head to keep the helmet from sliding too far forward on the suspension. Otherwise it starts to come over the eyebrow. That issue I have adjusted to. I was surprised that given Bell's great history they did not want to work a bit harder to resolve this issue as it does affect rider safety. Nothing stays the same, it appears.
Saved by the Bell! Bell helmets have saved my life twice. They are light, comfortable, and perform exactly as intended. They have saved me from a rampaging pickup truck and this winter protected me from a violent fall caused by a patch of ice. Why risk your life with any other brand? I will always wear Bell.
I bought this helmet because of its high rating in Virginia Tech's helmet testing. I bought M size and it fits my 59cm oblong head well. I've done just 3 rides with it so far, It's so light and well ventilated that I reach up and touch it occasionally to make sure it's still there. Cosmetically, I like the mix of high-viz color where it shows and matte silver where it doesn't. Still, I tell myself everytime I ride Falling is not an option to remind myself to pay attention and ride safely.
