This is my new toy. I replaced brakes, cables, housing, tires, tubes, and chain. I even trued the wheels and repcacked all the bearings. I set out on my first ride and I shift into the largest cog in the back, smallest in front and right as I start to go up a hill WHAM ! the chain jumps off the crankset to the inside. nuts on bar = :-(
I go back to the garage, tighten the friction shifter, make sure the FD is as close to the chain as possible without rubbing and that the front and rear cogs are in line (as much as they can be) and I set off again.... shift into the large cog in back - small in front - start to get of saddle to go up the hill and WHAM ! chain comes off the front again.
