Ever see a Sugino/SR Titanium Bottom Bracket?

the ebisu/raleigh ridden here is of that genre so i found

Both are high failure items, as every similar ti BB we've ever seen.

The Campagnolo version went through several revisions to no avail.

THANX.

Is the present-day TA Titanium 6/4 square-taper 115mm bottom-bracket
(Axix Light Professional) a similarly high-failure item ?? That was
my backup choice.

THANX. Are there ANY square-taper titanium bottom brackets that have
a significantly longer life than others ??

- campagnolo nutted non-hollow super record

- phil wood modern titanium or megaminium

- TA Axix light pro?

According to Phil Wood, its ti and mag/ti bb are rated as "safe" for
riders up to 225lb. Now, if I was 225lb, I would concentrate on losing
some weight rather than get a ti bb. However, if you're *under* 200,
then it might be safe enough, may be. I'm in the 195lb range and have
used a PW mag/ti bb. Seemed to worked fine. I recently switched over
to an NOS Sweet Wings crankset and love it!

I would stay far away from Campy SR ti bb!

Sorry, can't help there, we never sold that one. Made our "no ti
spindles" line in the sand before that.

Again I have no direct experience but I'd tend toward Phil Wood if
you're hellbent on a ti spindle.

My advice is to drill or omit something else instead. Or carry one
bottle and fill it more often. If one could simply _remove_ the spindle,
you'd only save about, what, 140 grams? A Ti spindle saves, uh, 50g? 60?

Admittedly we have not sold Ti spindles in a while but I did nearly
kill/cripple some nice trusting people before we stopped. Unless physics
has changed greatly, think long and hard about that.

I'm going to add my completely inexpert opinion here, more or less
saying "me too" on Mr. Muzi's policy.

I will ride the darndest things: rusty bikes, bikes I got at garage
sales, bikes where I have drilled holes in the stems to act as a cable
stop, bikes with ungodly mish-mashes of components, wheels making spooky
noises with the excuse "well, the new grease should stop it from blowing
up," and so forth.

My firm line has been that no matter what, the places I won't cheat on
are crank spindles and pedal spindles. I also have a general policy
against parts with weight limits, despite being below most of the
typical weight limits.

Why? Simple: Steel is mad strong for a given volume (and heavy!), and
yet nobody tries to shrink or skimp on maximizing the amount of steel
they can get into either conventional square-taper crank spindles or
normal pedal spindles.

This should tell you that in that application, as much as possible of
the strongest stuff possible is necessary. Ti ain't as strong as steel,
for equivalent volumes.

I take this so seriously that given equal pricing (and with the proviso
that my policy is for parts I would have to ride myself, or give to a
rider who I didn't trust to make informed consent), I would take the
steel parts over Ti parts in those places.

The weight limit thing is because I like a safety margin, and I don't
like parts that go out of their way to advertise their marginality.

The "drillium" BB cups where satin chromed steel. Only saw a few of them
back in the day. They were really well made.

Teledyne made a Ti BB spindle and so did Stronglight.

The Stronglight BBs show up on eBay from time to time. They have sealed
bearings and aluminum cups. I had one of these in a bike for a short
while. I found that the right crank arm was deflecting enough when honking
up a hill that the chain rubbed on the derailleur cage. I replaced it with
the same style but with a steel spindle.

So did Zeus, even before those guys IIRC.

The Sugino Mity Victory cups are satin chromed steel with lots of holes,
use with Mity spindles and 1/4 balls.
The Sugino Ti cups have a steel insert for 3/16 bearings. Use with Ti
spindle only. Totally different product.

I've never seen any of the Sugino Ti components so I can say anything
about them. I just remember that the satin chrome finish on the drilled
out cups looked really nice.

I seem to recall problems with the steel bearing races working loose on
the early Ti BB spindles. I had one of the Teledyne Ti spindles but pulled
it out and switched to a Phil BB after several local racers had Ti BB
spindle failures. I still have the Ti crank bolts for the Teledyne.
