These hubs take precision to the next level. R+D Lee is back to tell you everything you need to know about the new MBS Rockstar II hubs and Rockstar II XL hubs. These are available in two sizes, standard and XL. The standards come in black and are designed to take 6, 7 and 8″ tyres. The XL comes in charcoal and takes a 8, 9 and 10″ tyre. The other main point is the width is larger than before to give a larger contact patch with the tyres. A new feature is the fact the bearings are offset from the centre, allowing you to make the distance between your wheels smaller or larger. Finally these hubs can be balanced using our new balancing weights.
