The Var Tools Professional Hub Sim is a workshop-grade tool designed to make wheel building, truing, and hub servicing more precise and efficient. Built for professional mechanics and serious home enthusiasts, this hub simulator allows you to mount and tension wheels exactly as they would sit in a real frame or fork. By accurately replicating axle spacing and dropout interfaces, it helps you eliminate dish errors, fine-tune spoke tension, and ensure that every wheel you build runs straight and true once installed on the bike.
Ideal for use with truing stands and wheel-building jigs, the Var Professional Hub Sim is compatible with a wide range of hub standards commonly found on modern road, MTB, and gravel bikes. Its robust construction is made to withstand daily workshop use, offering consistent alignment and repeatable results. Whether you are building custom wheels, checking dish after hub service, or standardizing your workflow in a busy service department, this tool adds a new level of accuracy and confidence to your wheel-related tasks.
