How do I measure my total cockpit length?

Add the practical effects of frame reach, stem length and angle, bar reach, and hood position. The exact number matters less than being consistent in how you measure it.

Should I change stem length or stem angle first?

Start with the change that moves you the least and preserves handling. If the goal is mainly reach, a small length change is usually cleaner; if height is also wrong, angle may be the better first move.

Why does a shorter stem alone not always fix lower back pain?

Because back pain can come from too much drop, saddle fore-aft, or a bar shape that still leaves you overreaching. Shortening the stem does not automatically change those other loads.

How do I know if reach and stem is the main thing to change?

If the bike feels better or worse in a clear, repeatable way after one small change, reach and stem is likely part of the answer. If it stays ambiguous, move to the next variable instead of making a bigger adjustment.

When should I get a fitter instead of adjusting myself?

Get help if the bike still feels wrong after a few careful changes, if more than one contact point seems involved, or if the same symptom keeps coming back once you return to normal rides.
