This concerns a 1991 Bottecchia with 6 cogs in the back.

Here are some dumb questions:

1. Do I have any alternative other than purchasing a new freewheel with cogs?

2. I believe I made the new chain the same length as the old one. If I made it one link too long by mistake, would that cause the skipping?

3. Would it make sense to put the old chain back on (no skipping at all), and get another 1,000 miles out of the cogs before throwing them away?

4. Is it best to purchase a whole freewheel with cogs already on, or individual cog rings?

Thanks!
