'70s era Schwinn LeTour - changed my bearings and grease today. No special wrenches required, Woo Hoo! It seems to roll better, can't wait to really ride it. It was a dirty job but someone had to do it! Some nice bike shop open on Sundays gave me the a little grease in a cup because I couldn't find my 30 yr old tube ... I should go back someday and buy something. Maybe those awesome $80 gloves I saw! Gotta love Concord, MA.
