Hi everyone,
Thanks for the responses. I have been reading them on my phone and couldn't respond. Let me try to answer some of the questions. In addition to my long 100+ rides, I do commute in Baltimore where the roads suck. I do my best to avoid the holes but I have to hit some.
In addition to 32c wheels to absorb some of the bump, whenever I can, I try to make myself "light" on the bike by standing up, keeping loose, letting the bike move and pivot under me, etc.
One question I had that did not really seem to be addressed is if I get another build, how to I weed out the ones I shouldn't trust. For all I know the shop who built me my current wheel did everything right and the issues are unrelated, but I am hesitant to find out again.
