I got this via message, and I expect the answer to help more than one person (the problems are common):
I've got a Srrus Specialized that I've had maybe a decade and it's been a really fine bike. Biggest things I've got right now are a little too much give in the front brake lever, I'd like to tighten that up a bit to give more immediate braking with more immediate response from the lever. And of course not have the disc be rubbing the brake pads on release after adjustment.
Other issue is probably some minor adjustments to the derailers, most especially the rear, sometimes it skips gears randomly and it's not as precise as it was when I first got the bike.
Could you recommend some written tutorials I could follow as to making my own adjustments, or some really great video tutorials? I have a mobile bike stand so I'm able to work on it without too much difficulty.
Sorry if this message isn't something you normally deal with or you'd prefer to have me go hunt for the answers myself, but it seems like you are the kind of person who likes to give information out freely. And if something works that you don't know about, you'd like to hear about it so that you can provide that information to the public yourself.
Best,
