After a frustrating time yesterday evening trying to lower my preload to the first setting, I was able to do it just now easy peasy
I had been trying to do it with the tool from Takara's tool bag or a hammer and screwdriver. The thing wouldn't budge. After talking to @
Ducati999, I tried a pipe wrench like he suggested. It made some marks on the shiny silver piece, but worked like a charm, no help needed
It might be something little, but I'm happy, and I can't wait to see what difference it makes.
