So..
Im wanting to get my 1989 mtb back into pretty good condition.
As it stands, its already in very good condition and perfectly ridable. Seems pretty much great (but what do I know)
But over Xmas I want to give it a bit of TLC.
Things I am going to do:
1: New tyres (the 25 year old ones are splitting a little on the sides)
2: Tighten front deraileur cable (5min job but needs doing)
3: Realign front bakes (5min job but needs doing)
But heres where I am unsure:
I dont know whether to dismantle and regrease the wheel hubs and/or the bottom bracket.
Should I consider that they seem to be working fine (as far as I can tell) and thus as sealed units if it isnt broken dont try and fix it and just leave alone.
Or...
Should I think that after 25 years, even though the bike has never been hard-ridden, really its about time to dismantle and regrease those bits?
Im just not sure if the hubs and BB are things I should definately do or definately leave alone.
Other than spinning them and guessing, how do I actually guess if they need relubrication or not. Is it a case of doing a hand-spin and if it goes around on its own say 4 times its good enough?
Ive never done hubs or bb before, but am generally ok with mechanical applications.
So should I leave well alone or should I definately be doing these?
Opinions and/or advice appreciated
My thanks for reading
