I ride 8 miles 1-2x per week from Brooklyn to my job in Manhattan, near Union Square. I have a question regarding sealed (shielded) Shimano hubs on my 5 month old Kona Dew Deluxe. The hubs are adjusted very tight. In the old days (pre-dust seals) I would take a cone wrench and loosen the bearing adjustment, but I don't know how to do that now because the dust seal gets in the way and I can't access the cone with a wrench. Anyone know how to do this? I don't want to screw up the rubber seal.
