In fact I will be lucky if Park Tool does not send out a rep­re­sen­ta­tive to reclaim all the won­der­ful tools I own of theirs.

On Jan­u­ary 11th I put a new chain and gear clus­ter on the Ram­bouil­let. 856 miles lat­er I final­ly took the time to fig­ure out the annoy­ing tick­ing, click­ing sound I was expe­ri­enc­ing most of the time. I thought it might have been a poor match between chain and cogs. But no! It was a dis­en­gaged brain at the time of instal­la­tion. I’d thread­ed the chain out­side the met­al exten­sion between the two derailleur pul­leys such that every ped­al stroke was grind­ing it away. The image shows what’s left after 856 miles of grind­ing. Click­ing on the image will show bet­ter details of my mis­take. In the right, 2005, image the red arrow points out the chain mis­aligned over the then undam­aged exten­sion. You can also note in the right image how I was able to catch my mis­take in less than 856 miles 🙂
