I suspect that there may be some diversity here in the 50+

Do you work on your own bike. Are you just barely able to put air in the tires. Can you handle adjustments to the parts that are already on the bike. Could you change out simple parts, saddles, seatpost, handlebar, grips. How about something just a little more complicated, could you change a stem.
Are you one of the mechanic types who can take the drive line apart and put it back together complete with all the proper adjustments. Can you build a wheel or check a frame for straightness.

How does our 50+forum align with these questions. This is not a test of your skills, there are not any right or wrong answers. This is just a sampling of how the members of this forum view themselves.
