DA vs Ultegra triple durability

One reason you may want to choose DA 10 STI shifters over ultegra is
the warranty. DA (and I think XTR) warranty is 3 years; ultegra and all
other shimano groups are 2 years. Since the STI levers are not
rebuildable, that one year of extra warranty may be worth it. As for
its "throw", you should probably test ride the two and see if YOU
notice a difference.

The other thing to consider is the crank. If you're looking at DA 10
triple, does it still use a proprietary inner granny chainring? If so,
you're limited to one chainring, DA 30t. Not versatile if you want to
change to a smaller inner granny gear. The ultegra 10 crank would
probably be a better buy.

Finally, you may also want to consider using either DA 9 or ultegra 10
rear hub. DA 10 rear hub has an aluminum cassette body and you'll be
limited to only 10 speed cassettes. Further, the DA 10 rear hub places
the outer bearings *inside* of the cassette body, and thus, at least in
theory is very, very similar to Campy's design and arguably "weaker"
than the other shimano rear hubs.

Saw it in Milano-yes it is, a bolted onto the middle ring, small ring.

The Dura Ace 10 speed rear hub only accepts 10 speed Dura Ace
cassettes. Not the Ultegra 10 speed cassette. So you must buy the
$150 Dura Ace cassettes if your rear hub is the Dura Ace 10 speed. You
cannot put the $70 Ultegra 10 speed cassette on the 10 speed Dura Ace
rear hub.

Are the splines regular-height on the Ultegra?

Shimano says no, but what they mean is yes. They're like a horny teenage
girl.

10speed section.

(Unless this has changed since this was written? But I seem to remember
reading that even 2006 105 10s has the higher splines. Which might
indicate that alu bodies will eventually trickle down as well.)

Not so. The DA 10s rear hub will accept any shimano 10s cogset, from DA
to 105, available in 2006.

DA 10s rear hub is 10s ONLY-any shimano 10s cogset. uUltegra and 105
10s rear hubs are steel and 8/9 and 10s compatible. NOT deep splines
ala DA.
