Chuck,

Agreed on the breaking TA alloy cages. The crimped cages ones break, too, though. The top of the cage just shears at the stress riser where the crimp ends. At least that happened to the ones I used. Both styles seem to last about 6-10,000 miles in my experience.

The only lightweight cages I have used with success (beyond TA steel) are American Classic. A very smart design. Are they still within our timeline? When did they appear?

Also, anybody have a spare kit to mount an American Classic cage on a frame with no braze-ons? (It's a special clamp...)

Finally, happy holidays to all.
