Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

So I got my new IRO hubs today (pics)

I got them and I like them. I think...

The finish:
It is nice, one small spot where the anodize did not touch. Looks like a tiny silver spot, no big deal. The hubs are gun metal gray and the color looks great.

The graphics:
They are very ugly (knew this when I bought them), but easily ignored. Might try to remove them, any suggestions that would not ruin the finish?

Build quality:
Pretty dang good. Not as nice as my Pauls, but nice. The bearings are smooth and the hardware seems tough. The machining on the hub itself is really nice, no noticeable flaws.


Here is my concern:

I ordered these for the Rob Roy GB with 130mm spacing thinking that the hub shell would be wider like 130mm hubs I have had in the past, but all they did was put spacers on the axle to make it wider. Does that seem weird to anyone else? I guess it could be nice if I ever wanted to use these in a 120mm spaced frame. I wonder if could cause any stress etc. on the hub with hard riding? I plan on using this for some off road duty like light single track and CX riding.

do the bearing seals have NTN printed on them? bearing size?

thanx

ps

wider flanges would equal different chainline.

they look great. Iro always came with long axles for making it good with 130mm rears. I don't think they'd do it that way if they felt it weren't safe. Also Soil has a great point

yea i don't think they'd do it if it wasn't safe. Tony is a pretty smart guy. The rear spacing on my jamie roy is 130mm and the hubs have spacers to fit. It's been working perfectly fine for me.

Yeah, that's always been my number one critique about iro. Their logo design team (probably himself) is slackin' like suuuuper hard. I think the appeal would rise much more if they had a sick logo. I've actually been drawing some up to stencil on my bike... lol

I kind of like the IRO logos. The simple script sort of does it for me. Simple, efficient, no frills just like the bikes he builds.

The design just looks like a bad microsoft word font. Not much substance to it. It's very choppy, too.

Respacing the hub 10mm is a perfectly normal, rational, and safe thing to do. It will stress the a little axle more, but still well within range of what the axle can handle. Don't worry about it.

Why would it be? Most track hubs don't have hollow axles.

pffffft... if you are going to buy custom hubs and then have wheels built up, why not get the hollow ones ?

Sheesh.

They're not custom hubs. He ordered them out of an online catalog. Choosing a particular color doesn't make them "custom."

Anyway, doesn't the Rob Roy have 128 spacing, or something similar? I seem to remember that they went the Surly route and didn't commit to 130 nor 120. Of course, the Rob Roy is off the IRO website, so I can't confirm this, but I believe it to be true.

It has 132.5mm spacing so it can be used with either 130mm or 135mm hubs.

you can't! there is a reason why they are between 29-31mm center2flange, physical limitations.

my rob roy has a respaced iro hub just like that one, only it's their old hub.

i've taken it loaded offroad touring, mountain bike trails and raced it. no problems whatsoever.

these hubs will give you a standard track chainline, which is why they do it that way. as was stated, wider hubs would have given you a wider chainline.

thanks guys! I am quite happy with these. I will post some photos of the build once it gets off the ground.

P.S. I know that chainline would be different, I had a set of old Surly 130mm spaced fixed/free hubs that had a wider chainline.
