So, I've just installed a new pair of wheels on my daily driver. Whilst I had everything apart, I decided I might as well install a new chain and cluster and call it a yearly service, so I put on a new Dura-ace chain and an Ultegra cluster (28t). I've fitted a lot of new chains and clusters, and there was nothing unusual about how it all went together.
However, I have a strange problem. When I start to pedal under a small load to check everything, the tension arm on the rear derailleur jerks a bit and makes it sound like the chain's about to skip. When the bike is stationary, the chain seems to sit well into the jockey wheel.
I've fine-tuned the derailleur position, and I can change through the full range of gears. Initially I thought this was the upper roller was too close to the bottom of the biggest sprocket, but it looks like it has at least the recommended 2mm clearance (will post a photo shortly). I am a bit stumped; does anyone have any ideas?
Extra info: the rear derailleur is only about 10mo old, 11sp Ultegra short cage that should cover a 11-30 range. The chain I ordered is definitely 11-speed installed with the graphics facing outwards, using the old chain to get the length right. I gave the chain a good dose of Rock n Roll lube the night before, so it shouldn't be stiff.
