White Brothers Rock solid 29'er fork. This is the 465mm a-c version, which fits suspension corrected 29'ers. Disc only, post mount. Steerer is 7.75" long. This is as close to brand new as you get without it being in a box. It was on a show bike, ridden about 3 times then taken off. Looks brand new other than the lawyer lips have been filed off the dropouts for easy wheel removal. It's light, 810 grams actual weight on this one! $225
Used campy record crankset. 175mm arms, 53 39 rings. Condition is clearly used, but perfectly functional. The rings have a lot of life left in them and look better than the arms. Arms are in ok shape, 100% struturally sound, but heavy shoe rub marks and some cosmetic pitting. Probably would look good with some elbow grease and a buffing wheel. How about $80, which is far less than you'd pay for chainrings for these.
Singlespeed hubset. Front is used white industries hub, 32 hole, good shape, smooth bearings. Rear is a brand new Rockworks brand hub, 32 hole shimano singlepseed cassette body. Very smooth cartridge bearing hub. How about $75 for the pair. Might be willing to separate if you only want one.
IRD Alpina F triple front derailleur. Brand new, in the bag with tag on. 31.8 clamp or braze-on style, nice triple front derailleur designed for road rings. $30
