ISO 170mm crankset

[Igor]

I am going to build up a Romulus and looking for a crankset for it. 170mm, silver. Sugino XD2 would be fine, or something sleeker/lighter would be great too. Anyone have something? I'd like 50/34 or lower gearing

Have you had a look at the Spacycles cranksets? Specifically the TD2 super compact double. 

You can choose the arm length and the gearing. I have a 38-24 on my Appaloosa and will get a 44-28 for a Roadini build I am cooking up. Not expensive and they look fantastic!

I'll second the recommendation for the Spa cranks. I have both those and genuine Sugino cranks, and they're the same forging. See https://groups.google.com/g/internet-bob/c/yNE7e5iy6fg/m/M45KJfMEAQAJ, where I included some comparison photos of the two.

The Stronglight Impact cranks are another badge-engineered crank actually made by Sugino.

I bought this triple from Blue Lug. It is a nice crankset and works well.

Except it looks like the only length they have available at the moment is 172.5mm. OP wanted 170mm.

The BL cranksets are made by Andel for them. Someone posted on bikeforums photos of them with the box and packaging and as I suspected it was all the same as what I received from Andel direct when I ordered some RSC6 triples w/o rings a few years ago. While I too think they are superior to XD's because they are stiffer/thicker and have a regular bolt pattern, they don't qualify as sleeker or lighter ! With a 115mm BB the tread width is about 169-170mm. BL's suggestion of a 122mm BB is too wide though. I use a 115mm cartridge plus a 2mm DS spacer on my Bombadil for a 45-46mm chainline.

They also go by the name of Dimension Cross cranks in black, sold in the USA.

The path of least resistance is to get a set of the New Albion 170's for $28 from the Soma sale through Oct. 22.
