Square taper crank longevity
I was wondering about the crank longevity with repeated removal and reinstallation. I have read here of others going tens of thousands of miles which would indicate greater maintenance with repeated removal for service. Even every year or every other year over a 30 year timespan would be quite a few maintenance cycles. Do these regular reinstallations eventually cause the crank square tapers to expand and deform? I don’t ride enough for this to affect me, and most bikes I have or work on have greatly deferred maintenance. Just wondering. A quick google search didn’t really show much.
