The MBS FiveStar hubs are the standard hubs on the colt boards and also the bigger tyre boards like the Comp95. MBS basically took the really popular RockStar II hub design and modified it to work with both 8in and 9in tyres with a second inside rim and thicker wall thickness. The hubs are slightly wider than the rockstars so it fits the bigger tyre better and still allows the smaller tyres to fit nice. Even though the hub is a bit bigger mbs have tweaked the material used to keep the weight down so it's not super heavy.
This all makes the FiveStar hub a great all purpose hub for all round use and can take a 50psi loading and perfect for a set of larger tyres for muddy or rough conditions.
