IRO bottom bracket?
I need to get a cheap dependable bottom bracket. I just lost a bid on ebay for a Phil (cats got at me with like 30 sec to go). I can't ride till I cop one, so I just want something that's gonna do the job.
IRO has one for $20, and a lot of you all on this forum seem to stand by IRO's products. Does that go for their bottom brackets too?

For what it's worth, I've bought both good and cheap BB's over the last 12 years and never broken one.

What sort of crank are you using? Remember there is a difference between 'Shimano' (JIS) square taper and 'Campagnolo' (ISO) square taper.
If it's Shimano/JIS, a Shimano bottom bracket is a great choice. Cheap, durable, dependable, readily available. I'd recommend the UN-53 (about $16) or the UN-73 (about $28 from aebike.com). I've used a couple of them, and they've been bombproof.
If it's Campangolo/ISO, you're looking at either the Campagnolo SC-S (about $17) or AC-H (about $28). I've got one of these 'cheapie' BB's that has seen a lot of use, and it seems more worn out than Shimano BB's that have seen similar use.
I haven't had any experience with the IRO, but if you've got the option, go with the Shimano. Your mileage may vary.

really? I've been using a shimano bottom bracket (un-52 70x107 I think) with a Campy Athena crank for several weeks now. I haven't had any problems, but now I'm wondering if I'm mangling my cranks.

I'm using stronglight cranks that seem to have come with my semi-old school peugeot (they look like they are the same paint job as the frame).
How do I figure out what taper I have?

To specifically answer the question. I have had no problems with the IRO BB. More to the point, I honestly think that if I did have a problem with it Tony would help me out.
Perhaps you should email him about your question?

How old school is your Puegeot? Do you know your bottom bracket threading? If you bike is old enough...it is definitely French enough to have a French bottom bracket.
Check Sheldon's site for more info.
If it is indeed French - Shimano, Campy, and IRO are all out of question without Phil's cups.

SHIMANO.
I've used my un-72 (one of the older goodies with the metal ring) for over a year now. I've submerged it in 18" deep puddles, snow, slush, sand, salt, etc. Not a peep. I took off the cranks about a month ago and spun the spindle by hand. Still as smooth as the first day.

off of sheldon's site...:
"
ISO cranks (Campagnolo, Stronglight, others) won't go as far onto J.I.S. spindles as they ideally should.
J.I.S. cranks (most Japanese models) may bottom out if installed on ISO spindles.
In practice, you can very often get away with mixing these sizes, as long as you select an axle length that gives the desired chainline. "
I think Imma just buy the IRO and hope that all works well
