Question: Are these 2014 helmets or older models?
Document: I'll only use on the hottest of days, it vents well keeping my head cool. This helmet hurts and leaves red marks on my head, very crappy cheep padding. This helmet may look and is cool, but I would be wearing my older Airius 75% of the time.
Have been in a couple of accidents with these helmets. While one would prefer not to be a real-time tester for the helmet, can say with conviction that the helmet saved my life. Found out that Bell also has a great crash replacement program.
Also, this helmet shouldn't be named "sweep." There is almost no sweep to it. It's like most other helmets that look like you are wearing a bowl on your head.UPDATE: Returned it and bought a specialized helmet for half the price and the quality seems far superior. I am a cannondale fanboy that abhors specialized but they do make great helmets and bikes.
I consider the Sweep at the entry level of high end helmets. Fit, shape, style are good, but still a little on the heavy/bulky side. Not objectionably so, but still noticeable when compared side-by-side to say an Atmos for instance.The critical thing with this one is, it saved my head in a pretty painful crash.
I was in the market for a helmet, I decided it would be sensible to have something between my cranium and a potential car windshield. Being the miserly man I am, I tried on several $60 dollar helmets, none of which felt secure to my head. The sweep feels like it was tailor made for my noggin, it feels like a helmet much more expensive than $110.
This is my fourth Bell helmet and I couldn't be happier. This one replaced another Sweep that I cracked in a pretty severe crash, and left my noggin unscathed. Better to crack the helmet than the head.I find that Bell helmets fit my XL head the best and provide plenty of cooling thru the vents. Highly recommend this product, especially if you have an XL hat size.
Got this helmet mainly becase there are very few helmets out there that look goof and are affordable. I wanted to get a Giro but I cant see myself spending $150-$200 on a helmet. This was very afordable and looks great. My last helment was about 10 years old so it was time to get something newer with the amount or riding I was doing. This also keep my head quite a bit cooler on the long rider or steep climbs.
Overall I am happy with this helmet. Nice venting - nice and cool in the summer for sure. Looks pretty cool. My only beef with this helmet are the straps. They just don't seem to want to lay flat - mainly the two straps in front of my ears. Hard to describe. I've used Specialized helmets prior to this helmet and their straps fit flatter against my head than this one. Not a HUGE killer deal - I still like it a lot.
I had never owned a bell bicycle helmet before this so wasnt sure what to expect, turns out the helmet itself fit my head very well, the problem is the straps and strap buckles, seems like they did not put any effort into refining-engineering the staps along with the buckle and chin strap so ultimately the side buckle twists and hurts, and I really spent alot of time trying different adjustments. My other helmets made by Cratoni and Specialized do not have this problem.
I bought this helmet to wear during rides in the warmer summer months in upstate NY. This helmet has great aeration and a stylish look. As other reviewers have noted the fit ultimately depends on the shape of a rider's head- mine is a bit more oval so I find that Bell helmets fit a bit better than Giro helmets. I like how the visor is adjustable and that Bell provides plugs to cover the holes where the visor fits when it is not in use. Overall I am quite pleased with my purchase.
