WTB: wide/low double sq taper crankset

Fixing up a bike for a friend of mine. I'd like to find her a sub-compact double crank, something like a 42/28T or close. Sugino AT would be ideal. Will be used with 8 speed drivetrain. 172.5mm.

A complete crank would be nice but could also be interested in just 110/74bcd arms. No need for a BB unless it's a cartridge in good shape.

Thanks!

So where are you, yourself, looking? I'm not a seller.

you looked at the discarded bikes in the LBS, for cannibalization candidates ?

Cheaper, Get a triple, the 42t in the middle, 28t on the granny bolt circle .. toothess chainring on the outside..

or pay the premium price; Compass cycles reproduction of classic French cranks. https://www.compasscycle.com/shop/co...-double-crank/

Or the White Industries VBC, manufactured in California. SQ TAPER ROAD CRANKS ? White Industries

I think I have a 172.5 Sugino AT, I should have used rings at or around those sizes, too. I can check tomorrow.

The Sugino AT is designed as a triple, with two bolt circles: the outer one is 110mm for the outer and middle rings, and thus the smallest ring that will fit is 33T. The inner bolt circle is 74mm, and can go down to 26T. In order to make a 42/28 double, you'd need to run rings on the inner and middle positions, and leave the large ring plateau empty. But you'd still need to use a triple-length spindle to get the needed clearance for the 28T ring.

A better solution would be a crank with a smaller bolt circle, like the Stronglight model 99 or its Sakae Ringyo clone with 86mm bolt circles. You could then easily build a 42/28 compact double.

I have a Truvativ FireEx 44-32 175 mm. Triple crankset but came on a cross bike years ago set up as Shimano 9 speed double. Isis drive and I probably have a BB for it somewhere in the pile.
