Current state of my '91 SH600. Love the looks of it!
Drop bars will follow and probably a new Shimano gear too. Will take a little time though.
The plastic pins that expand the part that fits inside the top tube may have vibrated out. You might try a substitute of some suitable plastic, welding rod, perhaps even a round wooden toothpick.
Wow, that looks to be in great shape! About my size as well. Brian has reproduced the top tube cable guides if you are looking to replace the missing ones.
Who do like in the Grand Prix? Pulling for Vettel, the Haas cars, and Ricciardo here.
The black ones are plastic. Earlier painted ones may have been AL.What are these cable guides made from? I assumed they were machined aluminum.
