WTB - Brake calipers and levers, derailleurs, shifters, handlebars...

Hey all, 

Im about to start a tri build. Im looking for a few lightly used parts I still need. 

1) Brake Calipers: Looking for specific rear brake caliper to mount below the bottom bracket. Something of the likes of Tektro 725 and such. Also need regular alloy front brake caliper, silver, white or black preferably. 

2) Brake Levers: Any lightly used TT brake levers will suffice. 

3) Front Derailleur: Looking for Shimano 105 or Ultegra. Double. 

4) Rear Derailleur: Looking for Ultegra or Dura Ace, also prefer black color, but open to gray/silver also. 10 speed. 

5) Bar end shifters: Standard Shimano Dura Ace SL-BS79 bar end shifter. 10 speed. 

6) Handlebar & Aerobars: Looking for carbon TT handle bar/clip on aerobars. Internal cable routing. Width 42. 

Also looking for the following brand new, just in case any of you may have some of these... 

1) Cables and housings -Brakes 

2) Cables and housing -Shifters 

3) 10 speed chain, Ultegra or Dura Ace. 

I may be traveling a bit the next few days, so be patient if Im not able to respond posts and PMs right away, Ill get to them. 

Thanks!
