What spindle length for a new Suntour Superbe Triple?

I recently purchased a new (not NOS) Suntour Superbe Triple for my road bike. The bike is a Sorotta Nova X from about 1985. The rear hub is a 130mm wide Shimano 600 with a 8 speed cassette. A link for the Suntour Superbe Triple is provided below. I would like to keep the width of the installed crank as narrow as possible without risking chainstay interference or chainline issues. The Suntour website calls out a XL 118 for Compatible bottom bracket. Can I use a 116mm wide unit?

It depends on the width and configuration of your chainstays as to whether the shorter spindle will clear. Only a trial fitting will tell you. BTW, apparently the "new" Suntour is back selling under the old Suntour model names. I hope they are nearly as good.

Yes, I have high hopes for this crank. It looks good and the price was a bargain. It looks stout enough, the polish is smooth and the chainrings are pinned & ramped.

Sutherland's 6th Editions suggests the following:

For Sugino Triple - Which should be in the ballpark...

High Profile Crankset w/ 68mm Shell = 120-126 (131-134.5 also but rare)
Low Profile Crankset w/ 68mm Shell = 116-118
Super Low Profile Crankset w/ 68mm Shell = 111-115

=8-)

Other than that, guess away...

They aren't. I have a "new" Superbe Pro triple, and it's obviously melt-forged. I should've gotten a Sugino RD3000T crank: http://store.somafab.com/surdrocr.html
