Haven't ridden them, got the silly oversized tool ordered and some alu spacers... found I have a stash of alu spacers here, in the BB drawer and not in the spacer tray... the BB was crushing the plastic ones even with a strap wrench tightness.
Bought a load of SS and Ceramic bearings to fit BSA30 RF brackets a while back, sized 30 x 42 x 7mm, didnt realise they had a stupid tool size so it will be a vise-grip removal on the trail or bike shop if I stick with the ZTTO. Same bearing size, different tool... which nobody will have.
