The Bell Sequence was designed in 2009, and launched in 2010. This helmet was designed as a mid range helmet, but the sales team at Bell decided that this helmet was just too good to be sold for such a low price. The price was bumped up into the $100 range, and has since received 5 star reviews in multiple biking magazines!

Rated with 5/5 stars in multiple bike magazine reviews, the Sequence sits somewhere between full-on XC racing and just riding for the huck of it .

It's European and race inspired aesthetic speak of speed and performance. The Sequence has the goods to go for everything from the all-day XC epic to the 24 Hours of Your Town to the show-and-go after work ride.
