Academy Tools - Frame Fixture (ATFF)
Academy Tools Frame Fixture
Academy Tools Frame Fixture, an innovative, award winning and revolutionary bicycle frame jig for builders everywhere.
Unlike traditional jig designs, the Academy Tools User Calibratable Fixture Alignment System [patent pending] gives you the functionality you need to check and control the alignment of your frame fixture, at every interface, every time.
Our design negates the need for expensive and time consuming factory calibration, and subsequently high shipping costs, for which all of the costs are typically passed on to the customer. Most importantly; we’ve removed the risk of building frames on a jig that has unknowingly fallen out of alignment since being calibrated by the jig manufacturer.
In a nutshell; we’ve developed a professional bicycle frame building jig that, uniquely, gives you the frame builder control over alignment and yet it still costs less to buy and ship. There really is nothing else like it.
