I have completed some simple maintenance items. Used to be like cleaning my chain. I actually recently changed out the ball bearings on my BB of my touring bike. Something about cutting the cable to install new shifter cable. Dont wanna do that.
But, without paying big bucks on a fleet of bikes, I fear many of us just wait until it demands fixing? Is that a good idea. ? How many don't do maintenance on hubs, BB's for maybe years. ?
So, what is your maintenance schedule? Do you do it yourself. ? Take it to a shop for a complete annual overhaul? What maintenance do you do yourself. ? What do you have the shop do.?
