Neco yellow. Had since 25th of March. Got about 1/2mm of pad left each side. The worst wear of pads Ive ever seen. Had them on dead grind to start and they hardly worked, Kept slipping, And sliping backwards when pulling up to back wheel, Even on dead grind I lost like 3/4mm of pad. Got Sharp but light grind Like it says they sould be use on and now I have 1/2mm of pads left. What can you expect for £8 pads.
