IIRC, the 107 mm BB listed is an error. My Atlantis came from Riv with a 115 & the same crank you've got. When I replaced the BB, my measurements & research suggested a 110 would work. It did but just barely. I'd go 113 as a minimum. My crank has 175 arms and 24/36/46 rings.
No comment on the derailers (whatever Riv put on mine work fine) but IMHO the 11-32 8 speed is not a good touring set-up. Mine came with that & I found no use whatsoever for the 11 and minimal use for the 13. So most riding was in the 15-18-21 and the gaps seemed too big. I cobbled together my own 12-14-16-18-21-24-28-32 by subbing old 7 speed cogs for the lower 3. I rode that for a couple of years but still didn't like the 18 to 21 shift and the 12 wasn't much use. When that set up wore out I picked up a 13-26 8 speed and made my own 13-15-17-19-21-24-28-32 by using the 3 original big cogs with 5 from the 13-26. For touring this provides nice steps in the range that's actually used most. Harris makes this as a custom or you can blend a couple of cassettes together to create your own. Loads of fun. dougP On Feb 18, 9:09 am, Mitch Browne <mitch.bro...@gmail.com> wrote: > I'm putting together my first Atlantis and feeling my way along. > > Riv says 107BB and I think the Sugino XD2 they recommend is good but > unsure of crank arm length.
