Symmetrical cartridge bottom brackets - besides Phil

[Bruce Lange]

Does anybody know which standard-taper cartridge bottom brackets, other (cheaper) than Phil Wood,
are symmetrical?

I have in front of me a 68x115 Shimano UN-72 that is clearly symmetrical or very, very close
(within 1 mm).

But I've seen many UN-(52,53,72,73) bottom brackets that clearly have a right side offset. Are
certain lengths symmetrical while others are not? Does anybody have a chart that lists offsets? What
about Race-Face and other "aftermarket" bottom brackets?

I know Campy makes some, and that wouldn't be a problem except that I want to use a 130 BCD crank
for the intended application.

Thanks in advance,

Bruce

We're using a lot of the Tange #LN-56 this year. Nice product.
