Had a rummage and found a couple of black bars. Both are syncros straight bars with the silver shim. One is pretty tidy with no real marks to speak of, though it has no decals. The other has a few marks and the remnants of a blue syncros decal, and is a little sun faded I'd say. Both have been cut down to about 535/540.
Purple wise, I have the chill pills, a nos bullet bros chain tensioner, some x-lite skewers (removable lever, though one is missing the black outer rubber). A bikes worth of svelte titanium canti bolts (same as x-lite essentially, ti bolt inside an alloy purple outer, and a matching seat post bolt, various bottle boss bolts and other sizes and a set of 5 outer chain ring bolts (just the outer bits, not the inners as I think I used these with silver inners to match the inside of the cranks/chain ring).
Any of this sound useful?
