I have 2 items off my recently broken up Cyclocross bike. Scroll to bottom for pics....
First is the All city Nature boy steel fork. Used literally twice before reverting back to my old forks, its in almost new condition. The steerer is cut to 240mm and there are marks from installing the crown race. More info (measurements/angles etc.) and better photos than i could ever hope to take here:
Second my Tiagra level chainset. Very good nick but with obvious signs of use, especially from heel rub. BB is a lot newer being 4 months old. Chainrings are used TA and stronglight but nowhere near worn out. 172.5 arms, 44/32 chainrings, 110 BCD.
