Problems shifting, do I need a new chain?
I just bought a bike (80's Nishiki, 3 chainrings, 6 speed cassette, Suntour Power downtube shifters, Suntour AR derailleurs). At first I thought there was something wrong with the derailleurs or shifters: the shifters are weird, they are friction but they feel like they have a ratcheting mechanism inside.
Here are the problems:
1. Shifting from big to small is fine, front or back. On the front, its very difficult to shift up to a bigger ring, and going from the smallest one usually skips the middle one straight to the big one. Either way I need to push the shifter all the way to get it to shift.
2. On the rear, going to a bigger cog I need to overshift (push too far) and then let the cable back out a tiny bit.
I think I may just need a new chain, it seems really loose/wobbly, and I measured it and each link was slightly more than one inch.
