My only logic based guess as to why an ISO taper on a Japanese part is this; ISO was the dominant taper in track racing so Sugino followed suit. They never imagined us using the parts in the way we do so ... this is what we end up with. Mfg's that dominated the track market in the 80's & 90's were Campy, Suntour Superbe Pro (my favorite), and Shimano (10pitchDA-octalink after?) to a lesser degree I think (someone pipe up if I'm off on this please, I am assuming to a degree) In order to stay competitive with the Q-factor (space between the L & R crank arms when mounted) of the other mfg's. So, Sugino stuck with the standard which is ISO. Oddly the UCI is based in Switzerland and so is ISO ...hmmm. Anyway, I'm wayyyy to OCD about matching parts to their parent & sibling components to be bothed trying to figure out how to make something not meant for it work; but that's not to say other can't do that, as I have seen it done for years. When I bought my first Track frame in 2003 it came woth Suntour Superbe pro track 170's on a Shimano Un53 BB, I ran a miche BB for a long time because it was ISO and with no Drive side BB cup flange I could migrate the BB slightly to correct my chainline. With in a year a rare stash of Suntour track 107mm BB's showed up on EAI and I bought it for 100 bucks; it is and has been perfect. I would save up for the sugino BB if you can swing it, it will last for a long time if you take care of it.
I don't think I'll ever get the loose ball Sugino bottom bracket unless I get it for a comparable price as the Protype, Miche, or similar. I won't notice the difference, and the bottom bracket maintenance is more of a nuisance for me. If I got it, it'd just be for the OCD/cred factor.

Should I check this bike out? It's a BCA (Bicycle Corp. of America), which was some sort of subsidiary of Ross, but it apparently has Shimano 600, which makes me think the frame might not be total garbage. It looks to be in pretty OK shape, but the pictures are (of course) terrible.
Guy is asking $205 for it, but I figure I'll throw out a lower offer.
There's also a good chance that it's too small for me. And it has two different pedals.
If they still have your size, yes. Act quick, they are selling out fast.
Hm, after some consideration, I'm not sure if I'll get them. I looked at the Voler sizing chart, and I'm right inbetween S and XS. My small Hincapie jersey ended up fitting too big. Are bib sizes and jersey sizes normally the same?
Should I make my Leader's rims Deep Vs or H+ Son Formation Face. Aesthetically I like the H+Sons more but I have concerns as a "Clydesdale" (6' 220) about them handling my big ass. Would either be better/worse for a brake if I ever an one? I'm still riding brakeless, but as my oh **** moments increase I'm thinking of having at least 1 bike with one, the Formation face seem like they may not handle a brake well either, but I have nobody with first hand experience to back this up.
Considered those, not sure if Ben carries them, will ask. What kind of difference am I going to see between the two in terms of strength? the FF is the 'true' deep v profile 6_sl42_v2.jpg7_formation-face.jpg

I'm looking to pick up a second frame so I don't have to wear my road shoes for my 3 mile commute to campus, figured the IRO was a tad nicer than my Kilo. My other option is a Leader 720tr fir sale near me, brand new.
