Having quietly proved itself in the background of the industry for the past two years, the MBS RockStar II hub is finally ready for its debut on its first MBS complete mountainboards.

The RockStar II’s proven success is the result of state of the art design software, thousands of hours of testing, and most importantly years of refining the polyamide / fiberglass composite material and manufacturing process that makes them so strong!

We’re very proud of this hub, and we hope all who ride them will be, as well.

Features: Twenty mating bosses guarantee a precision fit between hub halves to ensure RockStar II hubs spin true from day one and for many years to come.
