BB cup sizing...
« on: January 07, 2012, 11:07 AM »
Tried installing Maxy Cross cups on my Street Beat but they dont seem to fit. Ive hit them very hard but they have not even gone in a small amount. Ive never had to hit cups that hard before! I thought American BB sizes were universal, do they vary...?
Also is there any difference between 3p cups & OP cups?
Thanks guys

Richard
