I have 2 of the Park wrenches. I'll use the one that fits best for the adjustable cup, and a Stanley Max-something or something-Max( it's yellow and black from a decade ago,10 or 12")) adjustable wrench for the top nut. Park wrenches are not precisely all the same, each wrench is slightly different, despite any claims from Park. A regular Crescent wrench is doesn't hold it's position very well, the Stanley does , once adjusted it stays put.
For the most part, I prefer steel headsets as it's harder than Al. If a top nut made of Al ever gets too rounded, I bought some inexpensive Tange Passage steel headsets a few years ago for like $5 each, and I'd use those steel locknuts as they are the same height as my other Tange headsets. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
