I have a Trek FX 7.2 which I purchased last summer. I have a total of about 400 miles on my bike. Last summer when I hit 100 miles I had my LBS tighten everything up (brakes, gears) since I had 1 year of free adjustments.
Fast forward to now, I am outside my 1 year of free tune ups, so I am looking for some help on these questions:
1) How often (in terms of miles ridden) do you guys have your bikes adjusted/tuned?
2) I noticed when I am in gear set 2-5 and upshift to 2-6, it is very rough and sort of "jumps" to the gear. How would I go about adjusting my rear derailleur to smooth out the shifts? Is this something I can do myself?
3) Same with brakes...I noticed that they aren't quiet as tight as they were a few hundred miles ago. How could I tighten these?
4) How long do your tires typically last before replacing them (in miles)?
Thanks for any help you can offer me...still new to the biking world and would love to be able to perform my own tune ups on my bike as opposed to relying on my LBS which are usually running about a week behind in their shop.
