It could have been the added load from the snow buildup under the fenders. But my Dreigang 3-speed hub is giving me problems in first gear. When applying a not-so-intense but fair amount of pressure (going uphill or from dead start), I get a skip in the pedal stroke where the hub seems to give then catches again to give me torque. I also notice the skip in second gear. Can't comment on third gear since I never really used it under any fair amount of torque today on account of the snow.
I ride this bike everyday and know it well - this has never happened before. I oil the hub on a regular basis (using Three-in-One). Any ideas if this is easily fixed? Being the throw-away society we are, I'm expecting the answer of get a new one. But I'd like to salvage this one sine it has been so loyal (on a 72 Peugeot). Appreciate any thought in case you've "been there, done that."
