here are a couple of GEAR cable stops I managed to turn earlier this afternoon.
same as above, but a 4.20mm bore, a 0.8mm wall, and a 2mm “end wall”. this time id say 4.20 is perfect snug fit, slight press in by hand.
same flat, and again, same comparison. obviously the gear ferrule is way thicker than the brake ferrule, so the downsizing here is notably more prominent.
same barely branded Shimano housing.
ill have them on a bike before next week is out!
