Can I tune either the force rear mech, or 7900 front? I think the 7900 FM has ti bolts as standard...
If you find out whether the 7900 FM has Ti bolts let me know. You can test them with a magnet-magnets won't stick to Ti but will to steel. Toronto cycles looks like a good source for Ti and Al bolts from what I can tell. I think Al bolts are slightly lighter, though not as strong, should be fine for the adjustment bolts at least??? Also Al is cheaper. Toronto cycles have a lot of tuning bolts for rear derailleurs too, though I'm not sure about SRAM. I just caught the back end of your thread, I think you have a Shimano derailleur? You could compare the bolts on that to the Force RM before you order.
I'm getting a 2nd 7900 FM off ebay, has a bit of wear by the looks (a year old, they must have either done like 50,000km in a year, or they really didn't have their derailleur adjusted correctly), but that won't bother me as I'm running friction downtube shifters for the front, and mostly stick in the one chain ring anyway.
