Bottom bracket sizing and converting

CM said:

I have a Calfee Tetra Pro currently running with a Campy Racing triple. After 10,000 miles I'm
going to upgrade the entire drive train...bit by bit.

The first bit is a set of FSA ISIS carbon triple cranks. As a rookie, I know the bottom bracket
for a triple has to be longer than a double but I can't find anything that tells me exactly what
size is needed. Looking at FSA's site, it's at least 113mm and more likely 118mm but that's just
educated guessing. Where I can I find this out and/or do you know?

Also, recommendation on high quality BB would be appreciated. It seems that Phil Wood doesn't do
ISIS (I could be wrong!) so any other recommendations? FSA has several.

Triples do not inherently require a longer spindle. Crank designers have great latitude in that
regard. Campagnolo Centaur double and triple cranks use the same spindle. There are other examples.

FSAs catalog is unclear on that point but 108, 113 and 118 ISIS are offered. Which model crank will
you use? I can check it for you.

FSA offer square, ISIS and Shimano format cranks in various combinations across various models and
materials. Confusing.

Condsidering it's a Calfee with a 34.9mm seat tube and fat-ish chainstays, use the 118mm one and get
the FSA BB, the steel one.

Out of curiosity, why did you specify steel?

Thanks!

I get it, ignore my previous post about your question. The steel BB weighs just 20 grams more than
the ti one and I think Ti is a poor material for BB spinldes or pedal spindles.

Much agree. Selling Ti BB/pedal spindles borders on a criminal act.

Then please say so (with warning statements) when someone brings up using Record Pro-Fit pedals. All
I hear (from Peter) is they are lighter than SPD-SL.

I'm serious- and I voted with my dollars- I do not sell them.

I have seen way too many rider injuries over the years from snapped Ti spindles of all descriptions.

YMMV, with any luck.
