Iro Jamie Roy Seatpost Collar?
 

I've been searching around and I can't find the right size seatpost collar for an IRO Jamie Roy I've been building up. The IROCycles website's contact us page is down so I can't use that either. Anyone think they can help me out?
Thanks.

[strike]A steel frame usually uses a 29.8mm collar but there are odd ball frames.[/strike] I have a good feeling yours uses the standard. Only one way to be sure through, measure.

EDIT: Just remembered IRO did make aluminum frames, I was on the assumption they only made steel frames with their end of life stock... a good ballpark guess would be it uses a 27.2 seatpost if I remember correctly which should mean a 31.8 collar; what live wire said.

My Phoenix used a 30.0 collar, but that probably doesn't help.

My iro mark v took a 27.2 post if that's worth anything to you.

I remember the Jamie Roys were aluminum and most basic aluminum seat tubes that fit a 27.2 post have a 31.8 clamp...most of the time, no guarantees though.
Of course you could always measure your frame....

Dude, come on!!!

I know, I know, what the hell was I thinking?
