I rode the new setup about 25 miles today. Lots of climbing and rolling terrain. No noises or roughness at all from the BB. After I got back, when rotating the pedals it feels as though things loosened up a bit.
Interestingly, I returned to a friend's email, in which he said he had the same issue when installing his. It died after 10,000 miles! I figure I will be in my 70s by then, so I think I am OK.
Also - as a sidenote - when I switched my Protons (13-29) for Zondas (11-29 custom cassette) initially, I had to readjust the rear der to get good shifting. That
was in 2005, so who knows. Yesterday during the rebuild I put the Protons back on, along with my first ultra-narrow chain. No adjustment necessary for the rear der. I guess I am a believer in the new chains.
