I just put a new chain on my bike. I thought the cogs looked OK. Have had no problems till now. Now, it seems I cannot get the gears indexed. They keep acting as if the derailleur is between gears. I try tightening the cable with the barrel adjuster, loosening... On the bike stand, pedaling by hand, sooth shifting. I start riding, chachunk... Chunk... Cha-cha, CHUNK...

Am I going to have to become the proud owner of a new cassette to run this new chain?

What are your thoughts?

Thank you.
