I'm mainly interested in the Sugino Impel 150x (7/8 speed) or the Shimano Alivio cranksets. As far as I know, the Alivio M410 is 7/8 speed and the Alivio M430 is 9 speed. I know the Shimano non-series M443 at harriscyclery or cyclepath.ca has 48/36/26 chainrings. I believe the 36 in the middle and 26 are more compatible with either snow or having some weight in panniers on a backrack. I even got a Sugino Impel 150x with 42/34/24 to go along with an 11-32T cassette on a touring bike I want to complete this winter. The other touring bike project I want to complete in the future I have a Sugino XD 350 with 48/36/26. (I wanted to use that with Ultegra 8 speed bar-end shifters on Paul Thumbies.)

EDIT: Whoops, I totally forgot the 118mm bottom bracket length. I guess you could always take a peek at the specs before. Maybe one of the many Alivio models would be compatible.
