The Bell Super 2 has replaced the original Super as Bell's aggressive enduro helmet. Bell made a number of changes to this version, making the Super 2 an even better helmet. Most notably a chin guard (or "Chinbar") can be added to all models of the Super 2 to increase protection for descending. That said, if you don't want the chin guard option, then the Editors' Choice Troy Lee A1 is the better choice.
The chin guard is sold separately as the Wraparound Chinbar for $75. If you think you will want the chin guard, it is better to buy the chin guard along with the helmet in the Bell Super 2R MIPS version. It will save you $10.
