Superior craftsmanship with modern technology and innovation!

The list below is a running data base of screw rims that have passed through the shop (data collection began on 5/1/2014). Some rims were threaded prior to coming in, others were threaded in the shop. The measurements were taken 0.1 inches from the rim surface at the rim/cup juncture with Bach threaded rim/underpart systems. Updated 4/15/2020.
