I have a few questions about SRAM braze on front derailleurs that I am hoping the guru's around here can help me with. To back up a bit I should describe my problem. I bought a used custom frame that has really flared seat stays. Very similar to the old Kelly Knobby X. I tried a couple of cranks I have that use outboard bottom brackets, both triple and double, to no avail as the arms would not clear the stays. I posted here a month or so ago and with the help of folks here and searching on the internet I thought I found the solution. I used a XTR crankset and road Octalink V1 bottom bracket. The arms cleared and the chainline looked great. However, much to my dismay, the braze on for the front derailleur would not allow adjustment low enough for the 46t big ring. A buddy sent me a bottom bracket from a triple 6500 crank and I set it up with a double 7700 crank I have. The arms are fine. I tried a 48t chainring that I have and as I suspected I will need to use at least a 50t, which I don't have and prefer not to go that big. I've been scouring the internet trying to find a solution to my problem that I highly suspected did not exist. Then I saw a possible solution. SRAM braze on FDers have two braze on attachment holes. So finally my first question; how much, if any, lower can I expect to get out of using the top attachment hole? Secondly; do SRAM FDers have a wider throw adjustment to the outside than a Shimano FDer? Lastly; which SRAM FDers are compatible with Shimano STIs? I know the newer ones with the yaw thing are not, but thought I read somewhere that some models are. If you are still here and awake thanks for your patience.
