Sort of related to the AT vs. XD discussion: I picked up a Sugino GX crankset
on eBay last week. The box arrived and the cranks are in beuatiful shape. 53/39
rings on a 130 B.C. This was originally on a Bridgestone RB-1. With the rainy
weekend ahead, my shortened riding will be supplemented by time in the garage
seeing if this set works out for me on my Rambouillet. That bike came stock
from RBW with the XD 48/36/26 triple. Having dropped 30 lbs in the past 6
months, and done a lot of climbing, maybe my legs will be okay with the change.
If not, I can always switch it back. Anyway, the GX set weighs 750g (about the
same as a modern Ultegra double) and seems closer to the BB like the AT
described below. I'll see how BB length/chain line works out.
If that works out, there is a 1st edition Shimano 600 to try out somewhere in
the UPS system....

The XD has more flare/heel clearance. The arm's are angled outward away from
the spindle hole, and thus can be used with a shorter BB spindle. They are
also a bit thicker in profile since they are not forged in the same was as the
AT's were. The AT is "low profile," which means the arms are straight from the
spindle hole to the pedal hole--no flare for heel clearance. Thus it's spindle
has to be long enough to get them out past the point where they'll clear the
chainstays.
