Hey, do any of you guys use,or have any experience with these components...ideally,the derailleurs? I have a chance to get one pretty cheap...like $45. It's this one...



Can you tell me if it's even worth it? Also,I plan to use it on the Kestrel Talon I'm building into a TT bike. I'll be going all SRAM Red if I end up getting this fd.

Thanks!

Phil
