this kinda stuff is so tricky, especially with buying a frame online..at least for me. even though they give you the dimensions, it's like reading russian.

jayrooney, im from the nyc area as well. do you know of any shops that sell IRO's, cause i'll just stop by one and try one for myself.

Bicycle Doctor on Grand st in Williamsburg usually has most sizes in stock.
you can test ride to see what fits.

standover height is something to consider, but you should consider top tube length first.
if the top tube is too long you'll be stretched out too far and your back may hurt.

im reading that standover height should be about an inch over the frame, but what about top tube length? i guess thats something that i'd have to see for myself, huh?

yeah, take a test ride and see what size you feel comfortable on.
also search the forum for frame sizing tips. this thread has some good stuff:

check out the online sizing calculator discussed in that thread too:

thanks man, i appreciate it. hopefully i can make it over to the shop you told me about and i can get on one of these things myself. how is the markup on iro's in a shop compared to the site?

I'm 5'10" with long legs, (33 or 34 inseam pants) short arms and torso. I ride a smaller frame so that the tt isn't too long. My group buy IRO is a 56 and, judging from the tt length compared to my other bikes, it'll be perfect for me.

To the OP: I think the 59 will be too big for you.

then i guess if they dont have the 56, i should go for the 53?

also jayrooney, does bicycle doctor in williamsburg stock IROS in complete?

Bicycle doctor usually has complete IROs in stock built up with a variety of parts.
If there's an IRO built up with deep v rims and you wanted a different wheelset, Alex will swap out the wheelset and change the price accordingly, same for bars seat etc.
the prices should be comparable to IRO's site.

no. with proper saddle height your feet wont touch the ground. if you are stopped and leaning to one side, that's a different story.

I am 6'1" and ride a 56cm with more post and stem than some and it is fine, I could go for a 58 too. I'd say you should wait for the 56cm. And go to a bike shop and get a sense of sizing before you drop a bunch of money!

the 53cm will be hilariously too small, and thus, the correct size if paired with a bandanna and colorful grips. the dimensions of a "59" are actually 55.5 x 57. this would be much closer, though perhaps a bit large if you have stubby arms.

if im looking for something close to an all stock IRO setup (if not the complete IRO setup) would bicycle doctor have it?

or would it be more beneficial for me to buy a variety of good decent part?

jay im not sure if you would know but would you be able to give me a range of how much they price the IROs? ill give a call later but a quick answer as of now?

damn it, tony doesnt have the 56 in stock...

im really thinking about a pista now, unless you guys got some suggestions

Sizing is a weird thing. I got my IRO built up by Trackstar and did my first ride yesterday. I swapped everything off my conversion of what I thought was the same TT length 54. I got the 53 IRO, and I"m 5' 9.5". They used my old setup as reference points. So I went from a 100mm quill stem to 80 treadless, and to my shock it fits. Does that mean the frame runs a touch big?

is trackstar stocking any iros?

trackstar had a few IRO frames in stock lst time i was there.
you can call bicycle doctor and ask if they have a 56.
Alex is curt on the phone, but he's a really nice guy.

I got in on the group buy and have been riding it around for a few days now. I'm 5'10" with a 32" inseam as well. The previous ride was a 59cm and the IRO is a 56. It's a bit weird going from a larger frame to smaller frame, and I'm not really into keeping the seatpost jacked up so high. Maybe after a few more weeks, the 56 will be more comfortable, but I'd have probably gone for a 59 if i could do it over again.

hey jay i gave alex a call, he's a very very nice guy and even suggested i come to try out a 53 later today.

maybe ill just buy my set from him even though i want iro parts...

well we'll see what happens. i think this sizing thing is a sham, everyone likes it differently so even when someone says a size its still not a concrete answer. i've read many post where 6'0 ride 56, which in that case puts me at 53. ill go try it out later though, let youguys know. thanks

did he say if they had any 56's? i might go next week when i get a chance.

no size 56 for forever

how is that possible? is iro making any other frames in a 56?

i was exagerrating, they just wont have it for a long time. Tony himself said they wont have it for another few months. if you want a bike now, i'd say try the 53 out at bicycle doctors since IRO sizing is often debatable and subjective.

im gonna go next week and try both. since im on the taller side of this predicament i might end up going with the 59 and a shorter stem and the seat set back. where in ny do you live?

not proud of it but... glendale, queens. You'll probably have no idea.

maybe go try a 56 and a 59 road bike at a shop, and see if the 59 is out of the ballpark.

really the most important thing here is to find out if the reach is way off.

+1 to testing. If you can't find a 56, find a shop that has a 59 IRO in stock & try it on for size.
