"Thrust Mod" I know what you may be thinking and it has nothing to do with anyones pelvic area.
Extremely simple. I drill a small hole .062" at an angle through the bearing and the main saddle so the hole intersects the main feed. This provides a rear thrust face pressure feed to prevent thrust bearing and or crank failure.
I have done this many times and it seems to really keep those surfaces in perfect shape. Thanks for asking Mike. J.Rob
