Profile Racing American BB Colors Retro 19mm
This is a 19mm Profile Racing bottom bracket in the Retro American Size. It fits many frames from the 70s, 80s and 90s. The new is size in Mid which is this size if you remove the cups and run just the bearings. If you have Profile or GT 48 splined cranks this BB will work in your older model frame, for example. Includes the tub spacer and the crank arm spacer cones. Make sure you check the sizing out carefully before you press in the cups, because they are hard to remove. Also, be sure to you the tube spacer so when you tighten the cranks you don't crush the bearings. The tube spacer can be cut or widened with spacers to allow perfect fit of your cups to the frame. Use the smaller silver crank are spacers to space your left arm off the frame about 5mm and to align the chain to the Freewheel. All BMX bikes have some degree of tightness and looseness when you turn the chain, so don't worry. Silver, Red or Blue with matching cone spacers. We have this same BB in the Bullseye Brand too for $129.99 in all the colors.
