FSA will soon be adding a significant amount of width to their Afterburner trail/all-mountain wheels, bumping up from 21 to 27mm internally. The asymmetric alloy clincher rims have a black anodized finish and are laced to hubs with Preload Reduction Assemblies (PRA) for the fastest roll possible. Charlie Sponsel of Team Robot fame did his best to smash a prototype set for several races last year, but they held up with great results.
