Isis splined BB

[MLee388407]

I was going to buy a race face signature BB but did some research online before
making the purchase. Ive seen some negatives about RF bearings wearing out
fast. This BB is pretty pricey to wear out so quick. Does anyone know a good
brand ISIS BB that weighs in around 200-250 gram range? TIA

Smaller bearings = faster wearing?

Pete, did race face redesign their signature xs to deal with their bearing
problems I read about on the net?

Spindle dimensions aren't a reliable indicator of bearing ball size.
For instance, Campagnolo Chorus spindles have traditional diameters,
but the balls in right-side Chorus and Record bottom brackets are no
bigger than 3/16". By comparison, the balls in a splined Ultegra
bottom bracket are, at 7/32", more than twice as big.

Dear John,

A typo, I expect?

I assume that the small balls are 3/16" or 6/32", while the
large balls are 7/32", only a little bit bigger.

Unless, God forbid, the Ultegra conceals 7/16" bearings?

Oops. A few days in Vegas at Interbike have apparently compromised my
sense of space and time. In an attempt to save face, I'll just pretend
that I _meant_ to say that 7/32" balls in the Ultegra bottom brackets
are half again as big (by volume) as 3/16" balls.

Dear John,

An excellent save! The pot is yours!

Now place your winnings on the color of your choice as I
roll this white ball bearing around a wheel that neither
stands on nor hangs from its spokes . . .

Sorry, incorrect math. 3/16=6/32. They're only a 1/32nd bigger.

Dear John, Phil, and Marten,

Oh, dear, we're quibbling and it's all my fault!

a) The 7/32nds balls are 1/6th taller than the 3/16ths.
b) They present 13/36ths more surface area.
c) They contain 151/192nds more volume.

Damn! If only I had a superscript ball for this typewriter!
