I see their web catalog explanations are as clear as mud ! Maybe that's why they couldn't convey it to you either. They have 73mm UN55's but no explanations, only this...
113, 118
122.5 x 73, 48.8 chainline
123, B23X, Right +2.5mm
sigh .....
This can't work for the Silver crank on a Susie ?
Well WHY ? .... simple question ... -:)
Just being honest, I tend not to want to deal with people that aren't able to give clear answers to my direct questions, or don't have the wits to ask me to clarify the questions, to be more specific to get a more specific answer. "Explain so a child can understand it" never seems to fail. "Why ?" can never be asked enough as far as I'm concerned. So to all those inquisitives asking repeatedly WHY ?.....I tip my hat to you in gratitude.... Y-Not !
I can't give you a specific answer about your crank/bb as much as I may wish to as I'm not a mind reader seeing things as they do. I have a stock of various length cartridges on hand and a bag of various spacers and I play around with the combo that suits where I want the crank to be in relation to the frame. Why ? :-) Because someone can "recommend" a certain setup and it be perfect from their perspective. That may or may not apply to anyone else though. It's no different that a mfr. spec'ing a certain spindle or chainline. It's proper from their perspective setting up, but doesn't apply to all the various possibilities otherwise. It is what it is.... let it go and do what you gotta do.. always with a smile .....

I asked about this when I bought my Gus and got no conclusive answers. I really did not get a conclusive answer from Riv either. When I ordered a bunch of components from Riv for my Gus build the answer I got about what BB to get went something like " we will look into it and send you the right one". The one I got does work but the box it came in does not give me the information I seek.Here are my questions. Gus and Susie have 73 shells. Riv does not list 73 bb's for sale. And they suggest which 68mm IRD one to get for your Gus/Susie - 123 width with right side spacer(?). Am I to conclude that 68mm bottom brackets work on a 73mm shell? An Tange bb has become available that is a 68mm with a 122.5 spindle. Will it work on my Gus. What about the drive side spacer?
Please excuse my ignorance. I would like to upgrade my bottom bracket and really have no idea what will fit best. I gather a lot of different spindle lengths will work but not ideally?
