Rear Derailer Question
I have a roughly 2004 Specialized Seqouia with a 9 speed rear Tiagra derailer. When I purchased the bike the derailer was missing a bolt and a Idler wheel, I purchased a replacement off ebay bolted it on and the tensioner pulley is rubbing on the biggest gear. Even with the screw turned in all the way so I bought a longer screw but I still have the same problem. Thinking maybe it was the derailer itself I swapped the pulleys onto the original derailer and bolted it on but I still have the same issue. Any suggestions? Thanks in advance.
