IRO or Sugino RD cranks?
I've got a toss-up between 2 fixed gear cranksets: IRO or Sugino RD. The price comes out basically the same (Bikeman has good prices on the Sugino crankset and BB, btw), so is there some clear difference in quality for those who have experience with these? To put this in context, I'm converting an old beater (Kabuki/Bridgestone). The bike will primarily be for commuting, with a little extra mileage on the weekends. I'm not looking to go high-end (obviously), but my current crank spider is done and I'd like a decent drivetrain.
Thanks.
Thanks.

I've ridden RD and never IRO.
Go IRO if ONLY for the customer service.

i think they are actually the same thing.
ive been riding 165mm sugino RDs with the 48t (16t cog) for a month or so and have no complaints so far.

The IRO is a true track crank, correct?
the RD is just a road double.

sorry i mean theyre made by the same people so there probably isn't much quality difference. just pick the one you think looks purtier.

Anyone know whether the Suginos put the pedals tighter in (narrower "tread" or "Q-factor" for the jargon-inclined)? Seems they might since the spindle is shorter with the chainring on the outside of the spider for a 42 mm chainline. IROs have a longer spindle and ring on the inside for the 42 mm chainline. Then again, the Suginos are indeed converted road cranks (as others have pointed out), so maybe the IROs have an adjusted pedal positions (e.g. narrower crank arms) to compensate? Perhaps this all has a piddling effect on pedal strike relative to just using shorter cranks and I'm wasting time thinking about it.

While the RD may be just a road double, the chainring mounts on the outside of the spider. That's +1 style points.

It is able to mount on the outside, but depending on the BB, often times it has to be on the inside.
