I'm always interested in looking rare and unusual parts for bikes. Best I've got is a Sunshine NJS hub from the 70s/80s and my cinelli bar/stem combo (though I'd kill for one of the ones with the big crest on the stem). I just lost an auction for a crazy red Brampton front red track hub on ebay. *sigh*
Whatcha got that's not so run of the mill? Pics are a bonus.
(yea its a slow day at work)
