Correct BB for Sugino 75 - You Decide! [POLL]

Let's say you had a Sugnino 75 crankset, but hadn't bought a bottom bracket yet.

Since you're riding the street, sealed>unsealed. After trying to find the right one, the many differing opinions around here have your head spinning. You're thinking Sugino 75 bottom bracket and be done with it, but your LBS is saying that's not such a good idea for street. Of the sealed bottom brackets, people have reported success with Campy, Dura Ace, and Phil Wood.

What would you pick?

I see four options premium options (try to keep it to these, but suggest a solid cheaper alternative if you must):

Campy Pista Record - 111mm ISO [~$105]
Dura Ace 7610 - 109mm JIS [~$145]
Phil Wood - 108mm JIS [~$120]
Sugino 75 - 109mm generally undetermined taper [~$80]

your options don't make any sense.... s75 bb is the cheapest and a for sure match where the other ones aren't... and if you have to go sealed and are considering jis, the cheapy shimanos will do it.

Sure it makes sense. I am riding street, have my own concerns about riding unsealed daily and LBS backed that up when I asked today. If there was a Sugino 75 sealed BB I wouldn't be bother with this. Promise.

if you're set on a cartridge, why ask? loose-ball bottom brackets are not hard to overhaul and are hella nice.

if you're set on a cartridge, get the phil campy taper one. that's the taper sugino says to use.

if you want a solid all-weather bb, then go with the phil wood, that's it.

if you want a bb that will match the sugino 75 cranks perfectly,
get the sugino 75 bb. not a difficult choice.

…but what's with the "generally undetermined taper"?

Sugino 75 = ISO. I emailed the company, and a man with the last name of Sugino (gives him a little credibility) said they are ISO and if you don't want to use an S75 BB, the Campy taper (ISO) is the way to go. He put this all into plain english so I don't think it was a typo unlike what some people are saying.

Anyways run the Campy, or the Phil Wood since they'll make a BB to match anything, it's your choice. If you run a Shimano UN5X, you're gonna deform the spindle hole but some people don't care about doing that... I run a C-Centaur 109mm btw, perfect chainline.

I ride mostly in good conditions, meaning I avoid most rain, but do ride in it occasionally. Reason for wanting cartridge is that I never want concern for my bottom bracket to dissuade me from going out in rain.

Thought that much was obvious. Want it so that I don't have to worry about water, whether from rain or just washing my bike down. I like the idea of sticking a sealed BB in there and forgetting about it for a few years.

Very little water is gonna get into your 75 while youre riding in rain. Its far from gaping open.
You get more water in your headset than that, easily.
Also, It takes no more than 5 minutes to have it all apart anyway.
Its too easy.

I ride year-round in Chicago, where some rain is the least of my worries. You can have your "too easy" BB rebuild; I'd rather be riding my bike heedlessly through the salty, corrosive slush.

So: Sugino 75 crankset on a Shimano UN73 for more than a year now. Perfect chainline. No problems. My crankarms haven't fallen off into the street. Fantastic bottom bracket for the price.

It may be that, when I remove the crankset from this bike, I will discover some irrepairable harm caused by the slightly different taper. At which point, I will have learned my lesson, or something.

But the endless hand-wringing on this subject is tiresome. If anyone is legitimately worried about some potential peril, or feels the need for a guarantee of perfection, or fears the wrath of giant NJS enforcer robots, just get the Sugino 75 BB and be done with it. Or, use something else. It's a track crank; most of us are already abusing the intention of its design, and no measure of nebbish anxiety will change that fact. For me, it seems to spin the same in any case.

and yet you asked and most people recommended the one bottom bracket that was specifically designed for the cranks and that does not have a cartridge. so why ask? you already knew what you wanted and no-one here knows whether you should get a campy or phil cartridge bottom bracket.

it's easy.

if you want cheap, get a cheaper campy bottom bracket (not even the record).
if you want proven, long-term reliability at greater expense, get a phil.

done and done.

.
Well, your conditions and the OP's condtions are clearly different. Probably why the overwhelming amount of votes are for the 75

This has nothing to do with NJS. There are only a few things to worry about with cranks: spindle shape, chainline, and stiffness. If we're riding 75's, we're doing fine with stiffness. Few here would ever ride any distance with a bad chainline. So why NOT wring our hands over the spindle shape? If there's one thing I don't want to get stuck with, it's my right crank arm falling off--if either the bottom bracket or the crank arm is destroyed, I have a lot to deal with, especially if I'm riding brakeless. It's very easy to get the proper spindle shape, so why not do it? I ran 75's on a shimano UN73 a while ago, and I had no problems then--but I may have. Now that I know, I'd rather not worry about it. When it's really easy to match the cranks with the taper they're designed for, there's no reason not to do it.

Oh, and if you're riding your steel frame through "salty, corrosive slush," you have many things to worry about even if you're not worried about your bearings. Just sayin'.

Because this is the conversation that will not die, to the extent that the entire internet is incapable of answering an ostensibly-simple question in any kind of definitive way; seriously... this is the most ****ed up search you can ever hope to attempt. I advocate the use of the Sugino 75 bottom bracket, if it will kill this conversation. Or some other bottom bracket, if it will also kill this conversation.

Yeah, that would suck! Use the Sugino 75 bottom bracket.

I agree! See my previous post. If you're worried, get the Sugino 75 bottom bracket, and stop worrying about spindle-shapes.

Unless there's some reason to do it. But I suggest you use the Sugino 75 bottom bracket.

Oh, I worry about my rustbucket. My daily ride is trashed in ways that only a bike that someone rides every day, everywhere, in every condition, can be trashed. But my bottom bracket is hangin' in there. As are my BB-mismatched cranks, which still seem to spin okay, and show no sign of falling off, or exploding, or turning into puppies, or whatever it is that we're really, really, worried about here.

you're the only one who seems to be getting all worked up about it. I don't ride 75's anymore, and if I did, I sure as hell would not be freaking out about it all over the internet. if you're so through with "this conversation," then stop joining it.
