I received the new pulleys and installed them early this week. They areflawless. The spacing is perfect for SRAM - I have theForce derailleur. They are as quiet as the stock ones (and less noisy then the older version - which I had). These are a super addition.
Your BB is the best, and the wheel bearings make a much bigger difference then all the "literature" says (I think this is because most tests on wheels is done "unloaded" so the difference between steal and ceramic bearing doesn't show as much) but under a load (which wheels always have - there IS a big difference). These pulleys really complete the package.
Thanks again for all the support,
Take care,
Joe
