-----
2/15 ~ HOT! Let the speculation begin! We're finally allowed to let you know the first official word
from Shimano on their next generation road group.

Dura Ace®, will be completely renewed. The new 10-speed system has been developed under the concept
of Speed, Smooth and Strength and this will be reflected in the product with its super-light weight,
high durability and high efficiency. There will be no need to modify frame dimensions to accommodate
New Dura Ace®. Interesting stuff that only answers one question, the number of speeds... we'll keep
you informed as best we can!

Anyone have some inside info? Care to speculate on carbon parts, chain width, cog spacing,
levers, etc?

Sorry folks. Only after posting did I wonder why day old news like this was not in the group. I
checked Dejanews only to find there was already a thread about this, started 2/15, but not yet on
my server.

No carbon, very similar to when Campagnolo went to 10s three years ago. New shape lever, chain and
cogset widths are gonna have to be real close to Campagnolo...not a lot of room to play with.

1 thing is sure: most of us don't need it, since chain and cog prices will be far higher and wear
will be signifcantly faster.(and it's far more sensitive too).

With Campag. 10-speed, component cost and wear and system sensitivity really are not issues. "Need"
is another matter entirely.

They said the same thing in the late '50s when 4-speed freewheels were being replaced by 5-speeds
that needed skinny 3/32" chains.

I am not against development and progress and everybody should buy whatever he/she wants to buy, but
I live e.g. in a flat country and must do my best to find a climb here. I really couldn't care less
if I have 10 speed or not. Some of my friends of mine who cycle here, who were doing races, and who
still are very strong cyclists only use 1 or 2 gears. I myself use 4 different ones here. I take my
bike often to S-W France and though I have both 8 and 9 speed bikes, I take the 8 speed with me (2
front blades). There I can do with 39/21 on 99% of all climbs. When they are REALLY steep I use
39/23. Therefore I don't want/need the more expensive 10 speed system.

Don't you agree costs are far higher for replacing parts?

First, these systems are not made for flatlanders. For you, I would highly recommend looking into a
fixed-gear, it sounds to me as if you would enjoy it. See: http://sheldonbrown.com/fixed

As to the expense, a fundamental reality of life in an industrialized wold is that of the economies
of scale that result from mass production. While, say, a 4-speed system might be more than adequate
for your needs, many other cyclists find more gears desirable. If a company were to bring back
4-speed for the small market segment that might want it, the tooling costs would more than wipe out
any theoretical changes.

There is no inherent reason why a system with more sprockets should be more expensive. Yes, you
have a couple of extra sprockets to buy, but that's it. The chain has just as many pieces, the
derailers don't differ in any qualitative way, and it costs nothing to put another notch or two in
the shifter detents.

In fairness, there is the issue of greater precision being required, but this is probably a Good
Thing in any case.

You can complain about the proliferation of gears and gadgets as much as you like, but the fact is
that Shimano has followed a consistent corporate policy over the last quarter century. In that time,
they have risen from a minor supplier to a position of world dominance. They would be very foolish
to alter the policy that has worked so well for them in the past.

They are in the business of selling bicycle parts. If they could't offer something new every so
often, their potential customers wouldn't have any reason to replace their old stuff, and the
company would go the way of Benelux, Chater Lea, Cyclo, Huret, Maillard, Simplex, Williams, Zeus...

It's not enough for me: though it's mostly flat here, we have VERY strong winds frequently: I use
39/15,39/16 then. Normally I'm perfectly happy with a 50/19, 50/18, 50/17 gear. Only with strong
backwind I use 50/13 or 50/14.Mostly I change the 16,17,18 and 19 sprockets of a cassette 4 times
before I change the other sprockets. The 21 and 23 are only used in S-W France.

Yes, if you need them you should buy them, but what I see happening is that people trade in bikes
that are good enough to win the Tour the France, just because another fashion is being "pushed",
like carbon inserts, integrated headsets. Things that are no progress IMHO. BTW:I heard the 10 speed
Campa is more likely to suffer from chainsuck then the 9 speed system. Of course, people are free to
do so,but there's no end to it if you want to ride what the pro's are riding. I see here that
serious cyclists often have older bikes and that most flashy bikes are owned by people who don't
ride often. But you're right: it's their money.

Another example: We now see all bikes being sold with a 39/53 combination. I see that most riders
are not strong enough to use a 53, so the chain is always placed on the innermost sprockets, causing
excessive chain wear. The first thing I did is install a 50 instead of the 53. I know I have less
available combinations, but the chain is placed in a more ideal postion now.

> There is no inherent reason why a system with more sprockets should be more expensive.
But that's my point: they ARE more expensive. At least here they are: a 10 speed chain is twice as
expensive as a 9 speed chain. A 10 speed cassette costs over 1.5 times more then a 9 speed cassette.
On top of that: wear is greater too!

> They would be very foolish to alter the policy that has worked so well for them in the past.
So we'll see a 50 speed if we'll live long enough :)

I just meant to say: it's not anything I can ger very excited over. I haven't seen any *real*
improvement since the introduction of STI/Ergopower shifting and modern click pedals.

When I go cycling I have just as much fun on my 12 year old steel 8 speed (just did 60 km on it
today) as on my new 9 speed Titanium bike. I do an average mean speed of about 31.5 km/h on either
bike. Makes no difference.

Greetings, Derk

To me, the most important improvement in bicycle technology that has occurred in my lifetime is the
L.E.D. taillight.

Consider the Light Man strobe then:

I wonder if the spacing will be close enough to Camay to interchange. Would seem that there is not a
lot of room to have something with much different spacing- as the number of cogs increase the
differences between the two company's spacing gets smaller, right? Gary Jacobson

Regarding prices, you may have selected cases where that is true but it isn't always true.

I pay $2 more for a Wippermann 10 chain than for a Wippermann 9. I pay $0.20 more for a KMC 10 chain
( nice chain, BTW) than their equivalent 9 Campagnolo 10 chains are indeed double their 9, but their
9 is cheaper than many others and their 10 is above average price. They have a wider price
differential than any other brand. FWIW Campagnolo's older Record-8 chain costs the same as their
new 10, but with so many vendors of 8speed chain who buys it?

As the installed base of Ten systems grows, you'll see more vendors and lower prices, I predict.
Especially if Shimano's new Ten uses compatible chain. Let's face it, if/when Shimano goes to Ten,
the volume of 10 chain will go up markedly and the price will fall concomitantly

I'm otherwise sympathetic to your arguments.

Of the big advantage to us the user, is that 9spd Dura-Ace will be sold off cheaply.

Here in the UK, when Campag stuff gets upgraded the older stuff does get sold off at a nice
discount. Shimano hasnt done this as things havent changed much for a few years.

I for one am looking forward to Dura-Ace 10 spd. I will be able to purchase maybe a couple of
complete 9spd groups for a nice price. That should keep me going for years.

Here the 9 speed exists next to the 10 speed Campa, without any discount....

Not always - Parker International still seem to be charging the full whack for their remaining
stocks of 8sp. Record Ergopower levers and the like.

The demise of Huret has rather a lot to do with the people at SRAM, though, who couldn't be bothered
with road components once they'd got their hands on the MTB side of the Sachs range. They seem to
have back-tracked a tiny bit and introduced a couple of Shimano-compatible 9sp. road cassettes, and
still (inevitably) do suitable chains, but that's about it.

I don't see the problem being that road bikes come with 53 tooth large chain rings, I see it as we
can no longer start clusters with cogs larger than 12 or 13. I remember being able to start clusters
with a 15 or even 16 tooth gear. A 53-14 is a slightly lower gear than a 50-13. A 14 tooth cog will
last longer than a 13 because the load is spread among more teeth and a 14 tooth cog has slightly
better drivetrain efficiency than a 13. We don't need fewer teeth in front, we need more teeth in
the rear. If you could start your cluster with a sane 14 tooth cog your 53 would be just fine.

There is the law of diminishing returns. I started riding seriously when bikes had 5 cog freewheels.
The 6th cog was a nice addition, we were able to narrow the gaps between the gears noticibly. 7
speed made even smaller jumps, often 1 tooth in the high end of the cluster. I was already thinking
that 8 speeds were not that big a deal when they came out; I really never found myself saying that I
wish I could fit just one more cog when I had 7. When things went to 9 cogs I remember thinking it
was sorta' nice that I could run just one cluster for both flat and hilly courses, I no longer had
to have multiple clusters because I could afford to carry cogs I didn't need. Then again, changing
clusters isn't that hard so what's the big deal? 10 speeds seems like serious overkill; especially
since I've read that 10 speed drivetrains have poor durability. Spacing rear wheels for all these
cogs creates so much disk that it makes it much harder to build durabile rear wheels.

stop the madness! Bruce
