New Gus & bottom bracket confusion

[Richard Rose]

I have decided to stick with a square taper crank, either White Eno or Riv Silver, and I have bottom bracket questions.

Gus BB shell is 73 BSA. The bottom brackets they sell (Shimano & IRD) are 68. Riv says "use the 113 (spindle) if you have a mountain bike front derailleur." But, they also say r.e. the IRD BB, "If you have a Gus or Susie with a tire up to 2.5", you'll need a 123 with the right cup spacer." But, they do not even show the 123 as being available?

Alternatively, White Industries offers both 68 & 73 widths but the widest spindle offering is 121.

So I guess my question is 1. If I go with a Silver double, which bottom bracket to buy? 2. If I go with a White Ind. Eno single, which bottom bracket? I plan to run 2.5"-2.6" tires.

Thanks in advance for our help.

No offense, but you're asking RBW business questions that would be addressed by them. Call them ! They don't bite.

Oh I agree & believe me I call them a lot! I just thought the collective brain power of this group might give me an answer before they wake up in California.

The forum, in part, is a good starting point for trivial questions like yours, Richard. If you aren't satisfied with answers, or lack there of, here then, of course, Riv is another option to seek an answer. You haven't committed a party foul, IMHO...

I'm faced with same issue, since I have a Gus on the way, too. I plan on trying a 107 and then a 113. I plan on using an XTR M900 set of triple cranks and using the middle ring only, as a 1x. You seek increased chain line by way of longer spindle. I am getting increased chain line out of using middle ring on my triple.

PM me if you wanna drill down on it. I need to sort it out, too.

It's certainly a valid Riv Bunch topic and one I expected to see shortly after Crust sold their new batch of frames. The knowledge bank on what works in the 73mm BB shells of these two Riv models is not deep.
