I asked Tim about gearing et al for BFs, and he offers the following.

your experience, but if anyone knows what works (or what doesn't), it
Personally, I wouldn't argue with someone who's fixed 'em all day long,
every day for the past 5 years ...
The bottom line is: Stick with standard Shimano chainrings. 53/39 for a
double, 52/42/30 for a triple. Nothing else is going to work as well.
the range on the Capreo, especially a 9-32 Capreo cassette, that should
provide all the gearing anybody will need - both high and low. Also,
Dura-Ace front derailleurs should only be used with Dura Ace chainrings
not Ultegra or 105. Ultegra and 105 parts play well together. But
should be kept to itself.
If you don't have a Capreo, then the standard Shimano rings won't give
much high end. TA brand rings work pretty well up to about a 58T size.
Avoid jumps over 14T for a double and 12T for a triple. If you
have to have specific sized chainrings, then the shifting quality will
uncertain. In that case, I'd highly recommend using bar-end style
for the front derailleur as it gives you much better manual control of
derailleur position than an STI lever. Actually, I'd recommend the
shifting any time chainrings larger than 53T, or non-Shimano rings, are
going to be used.
