When I called about getting my bike repaired I was astonished at the prices involved. Then I thought I've been riding long enough that I should know more about bike mechanics than I do and would like to be able to do the more simple things such as tune ups, adjustments, etc. At best, I can change a flat. I have a few trash bikes to try things on too.
Where does one go or what does one get to attain the knowledge to fix one's bike? Thanks!
