Shop mechanics use an axle vise frequently enough that many will have a dedicated vise set-up. if you are a pro or home mechanic who routinely removes end caps, adjusts hubs, or does any general service related to hubs, an axle vise is not only useful, but is the best way to secure your hub and prevent damage to hub parts. The Park AV-5 is the most comprehensive offering on the market. While it is true that sometimes simpler tools are better than diverse ones, the AV-5 is perfectly suited to the multiple sizes and formats found on today's hubs. As is expected from Park, you get a well thought out product with solid craftsmanship and attention to detail.

The AV-5 is essentially two blocks of extruded aluminum that have been machined to accommodate a huge variety of items that need to be clamped safely. The blocks feature retainers and integrated magnets to keep them secured and aligned while being used, and and to sit diligently in the vise for the next usage.The multi-faced machined openings feature jaw openings in the following sizes: 5, 9, 10, 12, 20, 25, 30, 36 mm. The AV-5 also includes a size for hydraulic tubing, a mini V-block, and a 1" hex for Park Tool Freewheel Removers, which basically covers just about everything a mechanic secures in a vise that doesn't involve a large hammer and under-the-breath cursing.

This is an ideal tool for home mechanics who work on a variety of bikes and standards, but may not own every single tool or the wide-ranging experience of a pro tech. With so much easily damaged, lightweight aluminum being used, the most important thing this $30 tool can do is to prevent you from damaging a $100 hub axle. Shop techs and race pros will love the sheer flexibility and comprehensive nature of the AV-5, and how it allows them to keep the at-hand tools to a minimum. Bottom line, if you work on wheels and hubs, this is a must-have.
