Never mind getting away with it - if it's the sort of bike where the bearings are serviceable, it's a good idea and will reward you with a nicer feeling and longer service life. (As opposed to sealed cartridge bearings which it seems like you may as well ride until they feel awful and then replace.)You may get away with taking them out cleaning/greasing and re-installing them.
Thanks for all the advice appreciate it but......took forks this morning and top bearing seems,ok but bottom was fu....d.I put.back together for now but which ones do I need ? Looked on wiggle etc but there's loads of different ones ?
When you say the bottom ones are fubar'd....youd be surprised. I stripped a headset for the same reason, rusty staining after some bad weather cycling....dear God, there was little lube left, just gunge and some pretty poorly looking bearings. Strip, tborough clean, work a load of grease in...they lasted another few years.Thanks for all the advice appreciate it but......took forks this morning and top bearing seems,ok but bottom was fu....d.I put.back together for now but which ones do I need ?
