Quoted from pinden007:I haven't tired those but you could get two of these for 50 cents if you can figure the size (which I haven't been able to do).
my pic from my GB
must say i'm still with these, working OK for sure
may be if you'll go for this, dont cut the ring as me, better remove the steel lane and insert properly the rings...
and sorry cant say what size these are, i had a full stock of various sides
now, about the Yoyo mods, its good too
he's here on pinside and could told more about it... PM him may be
PS : btw, this was my 1st GB, the one with ghosting & clearcoat probs
and you can see the clearcoat bad quality at the plot at the outlanes, with the circle marked in it
