I bought an old bike from a friend and the other day I decide to lube the hubs (it's my first time ever) on the Shimano R-550 wheels. Afterward, the noise in the rear hub just disappear - nothing, not even a single click. I took the bike on a centuryride and it ran just fine. My question: Is Shimano hub supposed to be completely silence or did I do something wrong with it? Thanks.
Sounds fine. I have the tool to take apart the freehub and I use it to replace the pawl spring with a heavier one. This allows me to pump grease into the freehub when I overhaul the hub. When the grease thins the hub is slightly noiser, but not like a Campy or Hugi.
