We still build the occasional compact 7 and 3x7 expedition touring bikes
for the same reason- 7 chain is much more durable and field serviceable
which matters if you expect to be beyond civilization (carrying water,
fuel, food on the bike).

For most riders, a telephone call to uber is sufficient for the rare
chain problem or tire gash.

Yes, and that's an illustration of different priorities. For me, "field
serviceable" is important. And the only time I've used Uber is to get to
or from a foreign airport. I'd hate to admit I needed it to finish a
bike ride.

ran me down. It's been no trouble at all since installed,
1998 or so.



And you have wrists like Hercules trying to get a bike to stop. Even
the change from the 2015 Campy brakes to the Skeleton brakes made a
huge difference in hand pressure.

There is a descent I did yesterday where the road comes around a turn
and comes to a stop sign with about a 16% grade. Just the carbon rim
pads make it almost impossible to stop at the stop sign until I
changed over to Campy Carbon pads. It made such a huge difference in
hand pressure I wonder what it is going to do to brake surface life.

The aluminum rims I'm now using on the Madone are like a return to heaven.

The cantilever Brakes I was using on my cyclocross bikes make stopping
under difficult conditions scary until I changed to V-brakes. The very
fact that so many people have changed to disk brakes is proof that
people did NOT like not having effective brakes. Not having to worry
about how effective your brakes are makes a huge difference in the way people ride.

You would be wrong about that. One or two fingers are enough
for most riding and it will lock up with moderate hand
pressure (unlike the very cute but crappy performance
Sturmey drum rear).

Then again my front rim's a Red Label. On chinese carbon
wonder wheels, all bets are off.

On the gravel/cyclocross bikes I had with cantilever brakes and Campy
aluminum rims you have to pull with all of your might to stop the bike
returning on that particular downgrade stop sign. I would prey no cars
were coming for that I could roll it.

Installing V-brakes made all of the difference in the world.

Classic cantilevers do require a bit more skill to set up and adjust
correctly. I suspect that's the problem you had.

We have classic cantilevers on our tandem, just like most tandems over
the past 50 years or so. I've never, ever had a problem stopping or
controlling speed. I did set them up with somewhat shorter transverse
cables than normal, but not tremendously unusual.

Try this: https://www.sheldonbrown.com/cantilever-geometry.html



Your tandem probably had medium, designs much like Mountain bikes did, but
CX bikes tend to have the wide, which have a low mechanical advantage and
thus my experience was similar to Tom, I did mitigate by using some Kool
Stop pads, which did mildly improve braking if at the cost of terrifying
wear rate.

The difference moving to mechanical disks which are far from top end, is
light and day.

In fairness would be fine (wide canti) on CX tracks or like, for Gravel
tracks and even on tarmac on the steeper/bigger stuff lacks the bite.

Roger Merriman


A few minutes with a tape measure would show you that
cantilevers are remarkably uniform across
brands/models/years in geometry/leverage. Vintage Mafac
Cyclo/Criterium and current low profile cantilevers are not
mechanically different in that regard. Their appearance is
different but not mechanical advantage.

Changing the transverse wire length does give a range of
leverage change as noted earlier.

DT shifters and five speed are fashion -- conspicuous contrarianism.

Really? At what point in time did my good friend, who has ridden her
Trek since the 1980s, transition from "I just love this bike" to "I'm
only doing this to be contrarian"?

I use all my 11 cassette cogs. I could give one up, but why? My
little lunch ride today was our standard loop of 16 miles and 1600
feet of climbing, full speed trying to keep up with my buddy.
Except for the roll into town (to see the post-riot damage),
everything was some degree of up or down. I shifted my way nicely
up and down the cassette, enjoying each and every cog.

I'm glad you love those cute little things, but: What did you have
before the 11? Was it a 10? Was there really a time you said "Damn, I
just hate that there are only ten cogs back there! When, oh when, will
they invent an 11?"

I doubt it. You probably told your ten cogs "You are all individuals,
but I love each of you equally!"

Seriously, I _never_ heard a cyclist complain about having the maximum
number of cogs then on the market. But every time the industry did the
N+1 move, there was quiet pride by the new owners who showed off their
N+1 and slight envy by the guys who had only N.

That was GM's 1960s tactic: "Wouldn't you rather have THIS year's model?"


You have all these imagined scenarios. I don't know anyone who went
out and bought 11sp simply because it became available. I was
riding 10sp until my wife drove my Supersix under a low overhang
when it was up on a roof rack. I also had 10sp on my CAAD 9, but
that went off to Utah with my son. I know I had some eight speed
shifters, and I think I put those on my sons old beater Windsor. My
first STI bike was eight speed.

I had 9 speed on my commuter, but I wanted to shift to hydraulic
discs, so I went to 11sp. That was probably a mistake, and I should
have found some 9speed hydraulic levers. Shimano does make them. So
I have some redundant 9sp Tiagra levers sitting in a box downstairs.

I had 7 speed on my old touring bike, which I did upgrade to eight
speed STI because the bike was spec'd with bar-ends, which I hate. I
gave that bike away. My tandem had seven or eight speed ERGO. I
sold that. I have one-speed on my track bike.

Anyway, the difference between 10 and 11 is, of course, one. I was
riding 10sp 12-25/26 cassette, so I got a 28 on the 11sp. I like
that 28 a lot these days. And I get to keep all my close range
gears. What's not to like?

Jay, I'm not saying masses of people threw away 10 speed bikes when 11s
came out.

But I am saying that if someone drove into a garage and wrecked an 8
speed they never complained about, they would buy a 9 speed to replace
it. Repeat for 10, 11 and now perhaps 12.

The important point is this: They were not unhappy with N gears until
N+1 came out. But by golly, when the opportunity arose, they would find
some way to justify N+1.

They just went with the flow. It is easier today to get 11 speed stuff
then 7 speed. Don't over analyze this.

Lou

I had to go with 11 speeds because getting 10 speed stuff was more
expensive. Shimano isn't rebuildable so the 10 speed stuff is
throw-away and the Campy parts to rebuild the levers was getting scarce.

The one weakness of the Shimano Dura Ace 11 appears to be that it
doesn't have a cable adjuster for the front derailleur and it is a real
bear to get exactly the right cable tension.

I don't get that. You can always put in an in-line barrel adjuster, no?
Is there something about Dura Ace that prevents that?

-- Jay Beattie.

No, build up a bike for a friend a couple of weeks ago wit DA. The inline
adjuster was included in the goupset.


Lou, had a haircut today.


Why bother forcing 10 sp? I don’t get that. I have 11sp because that’s
what came on the bike when I bought it. I bought it for a lot of reasons,
none of which was the extra cog.

Duane has to wait until June 15 for a haircut.

Fashion is a powerful thing! You really don't need the extra gears. If you were a better rider, you also wouldn't need hydraulic disk brakes -- or any brakes. I haven't used brakes in 35 years because I carefully plan how I ride, constantly watching the terrain, other riders, cars and even wild animals. In fact, I don't have handlebars because I am skilled enough to ride no hands, unlike riders today who are too afraid to even take their hands off the bars to shift. I can actually change my shorts while riding no hands. Two wheels are also unnecessary for a skilled rider and double the chance of getting a flat tire. When I tour, I want a durable bike with parts I can locate in a native village. I have had the same bike since 1975 and see no reason for this constant upgrading: https://tinyurl.com/yaer6n97

whether braking or shifting. ISTM light acting controls

only up to a point.

Of course. But light acting doesn't come for free with

is, the construction is a mechanical nightmare. I bought
it specifically
because both cables (bowden cable?), both those for

for changing gears are routed along the handle bar, so
that there is
enough space between the handles to moutn a large Ortlieb
handlebar bag.

Changing the inner cable is difficult, when one of the
wires is already
broken. Somehow I damaged an tiny spring while removing
the old cable.
In consequence, the whole expensive grip had to be replaced.
Unfortunately, this happended a few days before heading to
the south of
france for an already booked holiday resort.Â* Problem:
Shimano doesn't
sell that part, anymore, none of our local shops had one
in stock, the
national distributor didn't, either, there aren't any
compatible parts,
neither cheaper nor more expensive ones (neither 105 nor
tiagra are
compatible).Â*Â* After some frantic phone calls, in the very
last minute,
I got a shop who had the part and could be talked into
installing it
(with more time, I'd preferred to install it myself). Pfffht.

So now I own a bike with a very precious shifter, which
works quite well
as long as it lasts.

A year before, during a long vaccation in france, one of
my sons visited
for a few days.Â* For two days, he rent a road bike (a worn
BMC, if I
remember right) equipped with an old Verision of a Di2
group. I took the
opportunity to ride it too for a while, and was surprised
how well and
smoothly it worked.

These parts are certainly expensive, mostly because
Shimano is able to
charge that much money for it, not because these are
complicated. IMHO,
these are much simpler machines than the purely mechanical
6703 parts.

I'm currently not going to buy a new bike, but when I do,
i'll consider
a Di2 group, mostly because it's a much more robust
construct.Â* Some
goodies like some automatic shifting are welcome too, though.

But mainly, I'd really like to get rid of all those
arkwardly routed
cables, which break much to often.

Interesting. I have always used large handlebar bags on
(almost) all bikes. I prefer bar-end shifters, but I route
the cables under the handlebar tape, which is not the
default choice. But I don't have any problem with excess
lever force.

I'm sympathetic toward your problem of exotic parts and
expensive replacements. I greatly prefer mechanical
simplicity, and devices I can easily understand, strip and
fix in the middle of nowhere. That still keeps me away from
STI and di2.

I recently read in _Bicycle Quarterly_ magazine about a bike
tour in the remote Andes mountains. The tourists arrived
with brand new bikes with di2 shifting. In the remote
village where they started, they learned one bike's rear
derailleur did not work. One guy worked for hours with no
success, no idea of what was wrong. Next day he made a phone
call to a shop thousands of miles away and was given some
tricks to try. Fortunately, one of them worked. If it
hadn't, the trip might have been canceled.

I doubt I'll tour the Andes, but I don't want to be even 20
miles from home and have problems like that.



Agreed, poor planning. There are places where you can't even flash the
system software, a trivial setup step here.

Note that I'm not dissing Di2 or any electronic system but there are
places where it's not the best choice.Â* Along those same lines, the
farther you get from our consumer society the most common tire/tube
available is 26-decimal.

Yep. On our coast-to-coast, my daughter got a 3/4" slice through her
Terry front tire. That tire was really rare, something like 24" x 1". In
North Dakota, replacements just didn't exist.

We got by with lots of booting, stitching and next day air shipping to a
bike shop hundreds of miles away. But we should have carried a spare.

Oops. That was South Dakota.

That are really exceptional examples and I don't argue that those trips require different and well thought about set ups. But even then when something breaks beyond repair you need a replacement. Sending parts ahead to US Consulates is kind of cheating. First they should't got broken and if you should be able to repair it on the road and carry on. Can't you send a STI shifters to the US consulates?
What I meant is that the chance something breaks in our daily rides is so rare, often you did forget some tools to repair it and most people lack the skills to do it anyway so base your choice on field serviceability is questionable.
Colleague said he had to abort a ride (looking at the Holsteins) last week because the RD cable broke and called his wife. I said why didn't you fixed you RD in a suitable gear setting the limit screws of the RD. He didn't think of that. Riding buddy carried along spare spokes for 10 years and never needed them and beside that he didn't thought about that he probably needed to remove the cassette first.
My philosophy is that best first line of defense is buying quality parts and maintain your bike.

I was caught yesterday in two rain showers of epic proportions on the least suitable bike for those circumstances: aero road bike with rim brakes on CF rims. That was really scary, but I managed because of my highly trained skills ;-) and still managed a 30 km/hr average.

In fact, I don't have handlebars because I am skilled enough to ride no hands, unlike riders today who are too afraid to even take their hands off the bars to shift. I can actually change my shorts while riding no hands....

At last, you're beginning to learn!

I wonder if anyone else here ever saw Captain Dan Henry's roller riding
demonstration? He used to perform this at bike conventions. He started
by riding rollers fully clothed, and gradually disrobed down to just
shorts and shoes. He did this mostly by riding the rollers no-hands.

Getting the sweat pants off was the really tricky part. He spun up to
200 rpm (I put a stopwatch on him) and as the bike coasted down, slipped
out of one pant leg, then repeated the process for the other.

I saw him do this when he was in his 70s. Interestingly, he didn't use
toe clips (and clipless did not yet exist). He toured the world in dress
brogues whose soles he slotted to fit the pedal cage.

I think that the curmudgeon handbook, chapter six, has a lengthy
discussion of the benefits of DT friction shifters. IIRC,
they a (1) slow and imprecise shifting, (2) missed shifts,
(3) conspicuous contrarianism, (4) longevity like an incurable
skin condition, (5) inconvenient location, and (6) conspicuous
contrarianism. Clearly superior to any STI/Ergo like system.

A double dose of "conspicuous contrarianism" ("3" and "6"). Isn't
that overkill?

Perhaps (6) is better replaced by:

(6) Requires levels of skill not present in modern cyclists.

I think more accurate would be "requires total lack of skills that
modern cyclists have." Anyone that rides downtube shifters or
centerpull brakes in this day and age is either penniless or stupid or
both.

Thanks, Tom. I'm not penniless, I must be stupid.

Then explain how you have a downtube shifter bike? Unless you make a
effort to collect classic bikes you can't even find downtube shifters
anymore. I had a hard enough time getting bar ends for my touring
bike. And I've never even used it and it is sitting in the backyard

I bought one in 1978, still ride it. Some parts are new.

Wow, all my road bikes from the '70s broke or got stolen -- or
both.

Wow indeed! My family had precisely one bike stolen. My kid, when
about 11, was supposed to chain his bike to our carport. Instead he
just looped the chain over the crank.

Some years ago I very nearly lost my ancient bicycle. At the time it
had a sleazy Ofmega freewheel hub, due to my reluctance to respace the
frame. The hub was in the process of self destructing. When I applied
enough torque the rear axle would shift in the dropouts, and the wheel
would bump into the right chainstay. I never took it apart to figure
out what was broken.

But at the time it was the middle of winter, and I was lazy and didn't
deal with it. One day I rode a short distance to a yoga class in the
city center, and locked my bike in a large courtyard outside. When I
came out I unlocked it, just when someone told me I had left a
waterbottle behind.

I could have brought by bike inside, or locked it back up. But, since I
planned to be gone considerably less than a minute I foolishly just
leaned it against the building. When I returned some scruffy looking
dude was beginning to ride away on my bicycle. Naturally I yelled at
him, and took off running. He stood and mashed down on the pedal -- and
promptly dumped my bike in the middle of the icy courtyard, at which
point he jumped up and ran away.

Shortly afterward I spread the rear dropouts, and replaced the wheel
with one built on a Shimano cassette hub.
