I own both a road bike and a tri bike. I am wondering which bike I should be riding during off season training, or does it matter?

My back wheel needs to be trued up. It has a slight side-to-side wobble, and I feel at times like I'm going to lose control when I ride. Is this something that I should only trust to my LBS to do?

What are the essential mechanical/maintenance skills that I as someone who rides a bike should learn how to do myself?

How often should you have a bike tune up and what should be included? Is it unreasonable to expect a refitting as part of the tune up?

What kind of time difference would one expect in changing from a road bike with aerobars to a tri bike with aerobars over a HIM distance if using the same wheelset?

How do you determine VO2 max for cycling? I have my HR zones from a time trial, but don't know how to get VO2 max out of that.

I have a Specialized Allez Elite road bike with aero bars. It has the stock seatpost. I am interested in changing the seat post to one that is more forward. What would I look for?

The wheels are my first area of concern and I have started to shop around. I find it nauseating to think of spending the same amount for wheels as my bike. Any help?
