Hello all,

I hope this has not already been discussed in a thread I would have
missed.

While it is not hard to get marketign data, I am wondering about Shimano
CUES technical facts.

As I understand it:
* it is using the same rear cable pull for 9, 10 and 11s (and that cable
pull is /not/ the same as their previous standards);
* it seems available only with one or two chainrings but not with three
of them;
* replaceable chainrings seem to be attached with 4 bolts disposed in a
rectangle shape;
* it is using a new cogs and rings design called Linkglide, with
stronger (thicker) teeth and supposedly smoother shifting in both
directions, compared to Hyperglide?

Questions:
* Is it using a different cog spacing between 9, 10 and 11s, and
therefore, derailers with a different pull ratio?
* Any idea of the exact cog and ring spacing, as this is a crucial fact
for (in)compatibility with the existing?
* Does the chainring attachment match any previous one?
* Any idea of the exact front and rear cable pull?
* Any idea of other useful facts, such as cogs and rings thickness?
* I hope CUES cassettes are using the same attachment as Hyperglide
ones, has anyone checked this?

While I am certainly not ready to replace my entire transmission with
CUES, I am wondering whether I will some day have the opportunity to
replace part of it.

it’s not cross compatible with other shimano systems, it’s engineered for durability than performance apparently so can’t mix and match stuff. Ie it’s using a different technology with linkglide rather than hyperguide for chains/cassettes etc

front derailer that can work with that.

QUES does not use new technology. The spacing on the 9-10-11 are the same for their present 11 speed. This does make it necessary to change out all of the derailleurs and levers to use it. The cassette is steel but manufactured very light. The shifting
technology uses a system that lifts the chain both up and down improving the shifting and slowing chain wear. The move to more and more speeds was crippling the sales of the lower end bikes since most riders do not even like to shift at all.

There is no need whatsoever for a triple because a compact crank and a 42 cassette already is lower geared than any triple could achieve.

This is a bit harsh. As I understand it, CUES seems like a wrapping
around Linkglide, which is new technology. Or technological improvement,
if you prefer.

This does make it necessary to change out all of the derailleurs and
levers to use it.

Excellent news!

Linkglide.

The move to more and more speeds was crippling the sales of the lower
end bikes since most riders do not even like to shift at all.

Good move from Shimano, I always thought that the move to more and more
cogs was not really driven by consumers.

That said, I always saw and advantage of not having too many speeds:
thicker cogs and chains should be more durable. But if CUES cogs are
thicker and therefore even more durable than current 9s, we can not say
the same for chains, which will be thinner than that.

Or, to say it otherwise:
- with Alivio (or whatever), everthing (rings, cogs, chains and derailer
pulleys) is stronger in 9s than in 10s or 11s;
- with CUES, you always get stronger cogs, but otherwise, there is no
such an advantage of not having too many speeds.

The advantage of standardizing may outweight that. And a chain is not
too expensive anyway.

There is no need whatsoever for a triple because a compact crank and a 42 cassette already is lower geared than any triple could achieve.

And because there is no real need for so many gear ratios.

No way. Replacing an entire drivetrain just to have the same brand on everything may sound normal for people who have no better use of their
money, but this is not may case. I am proudly riding a bike with a
Shimano Alivio 9s derailer, matching cassette and lever, a chain from
KMC and a mix of the Shimano chainrings I was able to find (Alivio and
Deore I think, and I wonder if one of them was not labeled for 10s).

As the product manager from Shimano explained, CUES has been designed so
people can transition precisely without doing that. For instance, for
people with an existing Shimano 11s rear derailer: when your cassette is
worn out, replace it with a CUES one. Keep rings and front derailer for
next time.

For people with something that is not Shimano 11s rear derailer: when
your cassette is worn our, replace it, the derailer and its lever, with
a CUES one. And replace the chain with one designed for Shimano 11s.
Keep rings and front derailer for next time.

(:-0) My experience has been that "Cheap" doesn't always equate with
"Better" and in come cases "Cheap" turns out to be "Expensive", at the
end of the day (:_)

And, again, it has been my experience that "longevity" often equates

I once supposed that KMC and Whipperman were not as known as Shimano or

That said, I always found it easier to get solid facts about non-Shimano chains, including outer and inner width. This is important to me because
I have a 9s cassette while my wife has an 8s one, and I wanted to have a

I've read that KMC supplies chains to Shimano. I use KMC chain because
I've found a site that sells it in bulk. My Catrike requires almost 13
feet of chain.

For people with something that is not Shimano 11s rear derailer: when
your cassette is worn our, replace it, the derailer and its lever, with
a CUES one. And replace the chain with one designed for Shimano 11s.
Keep rings and front derailer for next time.

Stupid question: can I run a Shimano 11s chain on rings and a front
derailer designed for Shimano 9s systems?

Will CUES rings and front derailer work together with an older Shimano
system as well (i.e. can I start modernizing on the front side if I wish)?

I will need to upgrade a gravel bike starting with Sora, so I need to

Stupid question: can I run a Shimano 11s chain on rings and a front
derailer designed for Shimano 9s systems?

The only thing I see that may cause trouble is that its cage would be
wider than necessary considering the chain outer width.

I doubt it would be a very serious issue though, because the different
in outer width between a 9s and a 11s chain is about 1 mm. Far less than
the displacement the derailer makes to shift rings.

Actually, you can test that, because a non-CUES Shimano 9s cogs are 1.8
mm thicks, while a Whipperman Connex 11s chain has an internal width of
2.2 mm. (Why Whipperman Connex? Because they indicate their chain
internal and external width.) So you can buy one, install it and see how
ring shifting goes.

Will CUES rings and front derailer work together with an older Shimano
system as well (i.e. can I start modernizing on the front side if I wish)?

Well, as I see it, the only thing that links front and rear sets is the
chain, so as long as you have a chain that works with both, it sounds
okay.

I will need to upgrade a gravel bike starting with Sora, so I need to
wait until CUES bring racing-bike shifters anyways.

How will you /need/ to upgrade a bike? Want to upgrade maybe, but need
to? You may have to replace worn out components and take that
opportunity to upgrade, but I do not see how upgrading alone could be
needed at all.

Nothing wrong with Shimano chain but Campagnolo last longer
at higher cost for example while 'no name' chains are less
expensive with faster wear. People choose their own point on
those curves. Which is good.

As with most new product, 'It's a system'. Go with Shimano's
recommended all-CUES gear train (with your choice of
compatible chain)

For people with something that is not Shimano 11s rear
derailer: when
your cassette is worn our, replace it, the derailer and
its lever, with
a CUES one. And replace the chain with one designed for
Shimano 11s.
Keep rings and front derailer for next time.

Stupid question: can I run a Shimano 11s chain on rings and
a front derailer designed for Shimano 9s systems?

Will CUES rings and front derailer work together with an
older Shimano system as well (i.e. can I start modernizing
on the front side if I wish)?

I will need to upgrade a gravel bike starting with Sora, so
I need to wait until CUES bring racing-bike shifters anyways.

Chainrings yes, front changer maybe. Cable travel can be an
annoying incompatibility.
