I've just reminded myself of another reason I love TKCs on my GS - they're so easy to mount. A little lube, keep it centered in the rim, and presto. The rear fell in so easily I checked three times to be sure I didn't have the wrong size!
I guess I remembered a weakness too though. They get loud when they're worn. The new ones are always strikingly quieter.
I'm outta here. In search of loose terrain.
