Wear priority?

Glad its not just me finally pointing out its twen't the 'plain' flat profile rollers that hurt Combat reputation but a bad batch of bearings so Norton made up a new name for the replacement of better made off the self solution. I don't guess many relate this wear tear to expendables like foot pegs, levers and hand grips. i don't leave home w/o spare levers on my modern and clutch cable too. Plug leads vibrating on this and that tend to arc though in about 7-8000 miles.
