Some random stuff that I don't need:

Sakae Ovaltech 52/42 130mm BCD chainrings
700c wheels with 6 speed freewheel off late '80s Trek 400
brake levers, downtube shifters, and front derailler from same bike
Powergrips (2 brand new pairs)
Sugino Impel 150 42/34/24 crankset (rivetted rings, bought for project and never used)
Shimano BB-UN54 127mm (brand new, too long)
Ultegra 6600 front derailler braze-on (new, won't work with 52/42/30 triple, designed for 52/39/30)

I'd be interested in trading some combination of these things for:

Specialized Avatar saddle (new or lightly used)
46 tooth 110mm BCD chainring (new or lightly used)
good quality 26" knobby tires (new or lightly used)
new 7 speed cassette (preferably 11-28)
new 7/8 speed chain (SRAM preferably)
