Sugino XD2 triple with 10 speed system

[Jan RBW]

Has anyone tried 10 speed systems with Sugino XD2 cranks?

Rivendell's web page says: "Works with everything but 10 (or more--nice one campy) speed cassette drive trains."

Why wouldn't it work with 10 speed? Is the 10 speed chain too narrow?

Maybe change the question around a bit:

why do you want 10spd? What about 7,8, or 9? They should all fit on
the same hub body, I think.

The spacing between the chainrings on the XD is for 7/8sp chain. If
you are using indexed shifting for 10sp with 10sp chain, then the
front derailleur won't push the chain far enough to make the shift.
You could get around this if your front shifter is friction, but I
imagine there is a risk of the skinnier chain getting wedged between
the chainrings.

In my experience, if you are using 10sp, especially with STI, you
really want to make sure your drivetrain components match. Actually,
come to think of it, 9sp STI is pretty bad on the XD cranks, too, but
friction makes it better. Speaking of STI, the latest versions are,
IMO, much better than earlier ones. Uglier, too, but they work great.

You could brush off this topic and say "7-speed is plenty good for
me", which is true for most of us, but SRAM and Shimano are pushing
hard to make 10sp the standard for their mountain groups. There will
soon be many more gearing and shifter/derailleur options for 10sp than
there will be for 7/8/9sp. Personally, I run whatever I have lying
around, and have no preference as long as I can make it work on my
bike. I imagine I'll be using something 10sp in the not-too-distant
future.

I use a 9 speed chain and it works fine.

Maybe because that's what the shifters are?

You need a spacer behind the cassette for 7. Your LBS should have them.

If they are sti shifters then you'd just have an extra click or two
but it wouldn't DO anything.
If they are not sti shifters then who cares?

correct, for cheap.

The cable pull is different between 10, 9 and 8. You can't just take a
10 speed STI unit and match it up with an 8 speed cassette, it won't
shift correctly.

I didn't know that. My 9speed bar end shifters shift a 7 and 8 fine in
index mode so I assumed they didn't change it.

Bar end shifters aren't STI, either. You can get good shifting out of
an indexed bar end shifter even with substantial cable misadjustment,
simply by slightly overshifting enough to make the shift happen. The
floating pulley will make up the difference. You can't do that with
STI, though, so STI is far more sensitive to cable pull problems.

...except certain combinations ( Campy 10 spd shifters work with 8
speed Shimano cassettes for example) someone coined the term
"Shimergo"

I have used the Stronglight Impact with a Campy 10 speed system
successfully. The Impact arms are identical to the Sugino XD (with a
different logo of course). They use different chainrings and are
recommended for 9-10 speed systems. Square Taper too. I am planning
on using them on an 8 speed system next ... should work OK.

So if I shifted the front with friction, would XD2 work fine with 10 speed chain? Or would the skinny chain drop between the chainrings?

Never tried it, but my gut feeling is that there will be some kind of
problem using 10sp chain on a crank designed for 7sp (that said, I
have run 9sp on an old SunTour XC Pro crank with no issues). There are
now (or will be soon) many more 10sp MTB/touring triples on the
market, if you want perfect indexing. With friction, I'd be more
comfortable even with a 9sp crank, a Deore M590 for example, which is
available with silver arms and sensible gearing for a price similar to
the Sugino. These modern cranks also have the advantage of external
bearing BBs, which in my opinion are a leap forward (not that square
taper is bad, just that the new stuff has some advantages).
