There was a thread on the suginio rd recently. People didn't like it because the pedal threads were drilled 5mm away from where they should be, rather than in the middle of the bulgey section, if that makes any sense. Its a road crank with slight modifications. IMHO, the best deal on a track crank is the stronglight, but it is hard to find.
I just went out and looked at my RD cranks and I see the issue.
I can't imagine that Sugino spaced out on where to drill the hole.
They had a reason.
Anyway, I like this crank because I change chainrings and cogs more often than most people.
I guess I like to experiment.
This crank lets me put the chainring on either the inside or the outside of the crank spider arms, which gives me a lot more options on my chainline.
Not all cogs line up the same, and EAI cogs have two sides that put the teeth different distances from the center of the hub.
With an EAI cog and a Sugino RD crank, I have four possible chainlines.
An EAI cog, with the flange against the hub, and a Sugino or Shimano chainring on the outside of the spider arms gives me a perfect (absolutely perfect) chainline on my Pista.
Further, I like the 130mm BCD of the Sugino RD because it lets me run Shimano Biopace chainrings.
Harriscyclery has a long list of 130mm BCD chainrings in stock.
When and if I build an ice bike on a Steamroller frame I will use a Sugino RD crank.
People being picky about where the hole is drilled is pretty ridiculous. When your pedals are mounted, and your bike is set up, you can not tell that anything is different. Ken Cox didn't notice until he looked for it specifically, and he seems like the type of guy who knows his equipment. It's purely an aesthetic issue.
