I was quite pleased to have a spare while on the road with my brother near Saratoga Springs NY this weekend. I felt the clutch release a bit slowly and took a look at the cable. Maybe 2 strands were left at the point where the cable connects to the ball end in the handle. I had a spare, tied it to the clutch end of the old cable, pulled it through, and was back on the road in about 45 minutes.
Little brother no longer gives me crap about my ever-present tool/parts bag.
