Managed to bugger the olive while shortening my front hose. I've got the Tech X2 brakes with braided hoses. Wiggle list just one sized olive (it doesn't say what size), but CRC lists a 5mm and a 6mm. Which one do I need? IIRC the large one is for older brakes?
Also any tips for getting the olive over the cut end of a braided hose? Even though I cut it with decent cable cutters the metal strands kind of bulge the top making it too wide to get the olive on easily,
