Self-extracting bolt on ISIS spindle.

From the manual to my FSA Superlight crankset;

"Self-extracting crank bolts must never be used with ISIS spindles -
this will void the warrenty."

Why is that?? Self-extracting bolts are made for splined pattern
spindles, but are they only to be used on ShimaNo Octalink??
If so, what is the difference between ISIS and Octalink, besides the
spline pattern??

My TruVativ and RaceFace Isis BBs both came WITH self-extracting crank
bolts.

FWIW.

BS (no, really)

Many ISIS cranks have self extracting bolts BUT I recommend using the little
stud into the BB spindle end and using a conventional crank puller. Less
problems.

Not the least of which is stripping of the allen heads. What's the torque spec
for an ISIS crank bolt anyway?

I often find these statements that seem to abound in bicycling with no
supporting evidence or reason. I would also like to hear why this is
said. On the other hand, a company that makes hubs with three flanges
cannot be entirely credible.

As I said, FSA is and unbelievable concept.

I just got the FSA Gassamer compact crank and the platinum pro ISIS
cromoly bottom bracket. Only the self extracting bolts were included so
I emailed customer support on this. FSA sent me the bolts within 3 days.

I found the torque spec at the following location:

They also included a steel bolt for what I think is used to set the
cranks into position per the instructions. Using this should eliminate
problems with stripping the allen head.

But the FSA three flange wheels [1] look really cool when the bicycle is
parked outside the upscale coffee shop! Sometimes Jobst Brandt fails to
understand what is really important in cycling. He could learn a lot
from Fabrizio Mazzoleni about bicycle fashion. 😉

how about 'we're fed up with customers buggering up the threads with
unsuitable bolts and crying on our shoulder'? BTW it is sound advice,
and should be extended to octagon spindles as well imho

Just a modern interpretation of the lever tension driving wheel (sharp,
p 342), probably engineers having a bit of fun, but you wouldn't approve
of course 😉

My Truvativ cranks came with self extracting crank bolts AND self extracting
crank ring bolts.

The last time I removed my crank arms, I removed the bolts, tapped them a
few times with a rubber face hammer and caught them before they hit the floor.

I've been "away" for a while- did they finally get the tolerances on the
various tapers close enough that ISIS cranks will actually get tight?
