Our pocket balancer is a handsome, compact unit which can easily be taken anywhere a bike wheel needs to be balanced. All you need is something to hang it from. We've even heard of one of our customers hanging it from the handlebars of his mountain bike while it was hanging in the garage. The body is CNC machined of aircraft quality aluminum then black anodized for durability. The bearings we use are only ABEC 7 quality sealed beargins which provide for very accurate, quick balancing.
