[6pack] Gunst Bearing Experiences?

[John Mitchell]

I used the 15mm from the original instruction and have had no trouble 
with squealing whatsoever. I would go with least preload to start and 
add more only if needed.   John Mitchell  76 TR6  72 STag

My written instructions from TRF called for 25mm, but I talked with Dave Swauger yesterday about a related issue, and he told me TRF now recommends 30mm, and using the bottom lever arm hole instead of the top, as originally specified.
