1110.1 | how about 3-speeds? | CIMNET::MILLER | | Fri Apr 14 1989 16:51 | 4 |
| Also, does/do anyone ride 3 speed bikes any more? Do they even
still sell them for adults? How are they in price comparison? Who
would be the type of person who would buy a 3-speed? thanks!

1110.2 | a bit o gears | CNTROL::GANDARA | | Fri Apr 14 1989 17:19 | 16 |

I own an 18 speed, but its because of the style of riding I do,
touring.
Usually long trips where I am carring some amount of weight.
I need the lower gears to sustain my strenth for these trips.
You will find most racing or sporting bikes with a lower number,
12 or 14 gears (and a shorter chain stay). Racing bikes dont need
the depth because if you ever used those really low gears, you'd
be going too slow to compete.
Three speeds are right out, low budget bike.

Having owned bikes of almost every gear configuration, I
thought I'd give a try at answering some of your questions;
3 speed bikes; The gears are internal to the hub, and I
like mine for commuting. I like this bike for wet conditions,
since it seems the internal gearing works well in snow or rain.
They're usually bought by people who are afraid of more complex
gearing, and are much cheaper on the average than racing style
bikes. There's less maintenance, but rear wheel flats are
harder to fix. These are often good bikes to buy used, since
they are solidly built and are rarely subjected to the same
kind of abuse as racing bikes are.
On the 10 speed vs 18 speed issue, I'd like to divide that question
a little differently, and talk separately about double vs triple
chainring sets, then deal with 5, 6 and 7 speed freewheels as another
issue. By combining you can get a 10, 12, 14, 15, 18 or 21 speeds.
Double vs triple chainring sets;
The triple chainring set has one extra ring on the inside, which
is smaller than the other two chainrings. This allows for a lot
of lower gears on the bike. The low gears are an advantage for
hauling weight (touring), steep hills, or for just being plain lazy.
A real low gear is good for riding at walking speed, for holding
conversations with joggers or going slow through crowds.
I will probably never buy another bike with only two chainrings.
The third chainring is worth the extra price, even if you rarely
use it. I would certainly want a triple chainring set on any
touring bike, where I would expect to be hauling packs. I have
never seen any real disadvantage for having the extra chainring.
5, 6 & 7 cog freewheels; (this is a complex subject!)
The more cogs you have, the closer together your gears are.
For instance I might have a 13 - 24 freewheel in any of the
three kinds. The 13 is the high gear and the 24 is the low
gear. for a five speed I might pick; 13 15 18 21 24. For
a six speed; 13 15 17 19 21 24. As you can see the shifts
on the six speed are between gears that are closer together
than on the five speed. Having more gears to pick from
allows the rider to pick a gear closer to their optimum pedal
cadence. The disadvantage is that you may spend more time
hunting for that perfect gear.
Some brands of six and seven speed freewheels also allow
for smaller cogs, like a 12 for instance, which would provide
a higher high speed gear. A smaller cog will wear out the
chain quicker. In general a 14 for the high gear will
not cause excessive chain wear, but when you get into 13's and
12's chain life drops off.
With freewheels, another consideration is the hub dimensions.
The hub width may only allow for a certain size of freewheel.
A rear wheel is dished, so that the spokes on the freewheel side
are steeper than on the other side, and this makes the rear
wheel a little weaker than a front wheel which is symmetrical.
The more the wheel is dished the weaker it may potentially be.
So, using a wider 6 or 7 speed freewheel will require more space,
thus more dish on the wheel. This is really the only significant
disadvantage of having more cogs, in my opinion. Most racers
would go for the extra gear and don't worry about the slight
possibility of breaking more spokes. (note: when spokes break
it's almost *always* on the freewheel side of the rear wheel, those
same spokes which are put at a steeper angle when the wheel is
dished!) Another very slight disadvantage is that the 6 and 7
cog freewheels often use narrow chains and have the cogs closer
together, thus shifting can be less crisp, particulary when the
chain is dirty.
Five speed freewheels are always wide spacing, seven speed
freewheels are narrow spacing, while six speed freewheels are
available in both wide and narrow. Most ATB bikes with six
speed freewheels are coming with wide spacing, to allow for
easier shifting, although this requires more wheel dish. Hubs
generally come in two widths; wider hubs can take a normal
spacing six or a narrow spacing seven. The ones with a shorter
axel can take a normal spaced five or a narrow spaced six.
( Other hub widths exist though, like on tandem bikes, for instance,
which are even wider than the standard seven speed hubs. The
extra width is often used to allow for symmetric spoking, so
that the rear wheel can be undished like the front.)
In general I always go for more gears, with the highest high
gear I can get and the lowest low gear I can get. :-) (My ATB
currently is a 21 speed, with 48-36-24 in the front and
12-14-16-19-23-28-34 in the rear.) The capacity of the deraillure
is an issue when selecting gears, since many deraillures will limit
the size of the large cog (low gear) on the freewheel. Also
the rear deraillure has to take up the slack chain, and the
wider the gear range the more chain slack there is. On my bike,
I have exceeded the capacity of the deraillure, so I have to be
very careful to never shift into the 48-34 gear, since there is
not enough chain there for it.

1110.4 | no answers here. | NOVA::FISHER | Rdb/VMS Dinosaur | Sun Apr 16 1989 11:56 | 34 |
| To me "10-speed" is a generic name. I think the difference between the
'10' and '18' depends on the type of riding and type of rider involved.
Everybody calls 'em 10 speeds but where do you find 10 speed bikes
these days? Department stores: Pretty cheap stuff, usually. Even then
they sell a lot of 12 speeds.
A lot of older good bikes were 10 speeds. Nowadays all the good bikes
are 12 or 14 speeds. When you get to usable gears, the 10sp usually
had 8, the 12 has 10, the 14 might have 12. When I bought my first
bike back in 82, almost everything available was either 12 speed or
15. Nobody was putting triples on 6sp freewheels. It did not take
me or them long to revise that. That 12 becams an 18. In 83 I bought
an 18sp. and changed it to 21.
So what's an 18 speed? It's got a triple crank. These can be had
at an entry level price for only a few bucks more than a comparable
double crank. If you actually go into a bike shop and say "what kind
of 10 speeds do you have?" I don't think you'll find many. I think
most dealers might have one or two but if they do they'll show you how
much improved the [more expensive] 12 speed is.
I think a rider just getting into the sport who might be a bit over
the hill athletically, who is trying to not be a couch spud anymore,
is likely to have good use for an 18. The 18 will let him climb hills
reasonably, especially here in New England, and get in shape. If he
then gets in shape and decides to tough out the hills a bit, he might
be willing to forego his triple and get a high performance bike.
Almost all of my 12 speeds cost more than my 18 speeds. There's more
to it than price. I ride my 12's (most of which are really 14's) about
20 times more than my 18's.

1110.5 | PURELY SUBJECTIVE/MOSTLY | WMOIS::C_GIROUARD | | Tue Apr 18 1989 08:01 | 22 |
| Most of the responders touched on the common denominator. That
being "what kind of riding are you intending to do?"
18 speeds are good for ATB's and (if you're packing for cross-country)
touring. Otherwise, I really don't see a need to go the extra chain-
ring. You can usually get the flexibility you need in the freewheel.
Most un/semi/serious recreational cyclists can get by quite nicely
with 12 speeds (I'm talking the average human here). In fact, if
you ask how many of the gears are actually used, I'll bet the majority
will respond something like 6-8 (if that many).
It's very subject. I think many people opt for 18 because they "think"
they'll need them all. If someone become "regular at the sport"
(not fanatical) I'm sure they'll eventually admit to the fact that
there's too much hardware. My opinion, of course. I consider myself
a serious recreationalist. I'll do informal TT's and Citizen's races.
12 speeds is more than enough. I think I use around 6-7 regularly
(at the most). Why do I have 12? Hmmmmmmmmmm. Good question.

1110.6 | In defense of the triple. | BANZAI::FISHER | Rdb/VMS Dinosaur | Tue Apr 18 1989 12:12 | 8 |
| Ok, this note is sounding too macho. I know several riders who do
between 2000 and 4000 miles a year who make good use of a triple.
They do not particularly want to get out of the saddle on long hills,
they do not want to strain all that hard, they want to enjoy themselves
and the scenery. The 15/18/21 speeds are for them. (Of course, in
"usable" gears, this is only about 10/12/15.)

| Please do not misinterpret the meaning. All I meant was that, like
snowflakes, there are as many needs in the "gear" department.
I'm pro-any cycling. It's a great sport or ACTIVITY that ANYONE

always be tops in my book!

1110.8 | Yes, something for everyone. | NOVA::FISHER | Rdb/VMS Dinosaur | Tue Apr 18 1989 12:57 | 9 |
| I just felt that this was a case where a "silent majority" had not
stated their opinions.
I think the greatest thing about cycling is that almost anyone can
do anything they want to as long as they have some realistic
expectations. And as we add a bit of technology here and there, more
folks can enjoy it, too.

1110.9 | Silent Majority Speaks | ICBB::JSMITH | I Bike Solo II | Tue Apr 18 1989 13:39 | 24 |
| I can't take it any longer. This note is begining to take on the
flavor of the "Tastes Great", "Less Filling" debate. If your like
me you'll probably buy a triple and then later on buy a performance
double, but still ride the triple most, because like Ed stated
earlier, there's hills in them there hills. So my advice is not
to limit your thinking to a single bike when you can easily and
economically have several (I bought a Shogun 200 double in great shape
but missing the back wheel for $7.00 at a Police Auction). Then
the urge to ride in the dirt sets in and its a whole new ball game
all over again. As -1 stated the important thing is to get out
and do it by makeing an initial choice, knowing full well that if you
intend to pursue this sport seriously you will inevitably end up with
a complete stable of frames to choose from (In Ed's case several
stables) regardless of your financial means, since bikes are so
affordable (I'm talking about the low end used market here) I
personally don't know any *serious* cyclist that uses one bike for all
occasions. I happen to own four, two doubles and two triples,
not counting my wifes, kids or the one I have set up perminently
on the wind trainer, and I've only been doing this seriously
for about four years. So start where you will, but sooner or
later if you stick with it you'll own at least one of each.

I suppose the blame goes to the author. Controversy was bound

I think that the orignal noter meant "complexity of use".
Three speeds have had indexed shifting since 1904.
The design is cleaner, but the mechanism is not. How often do
you have to take up the toothbrush to clean the gears on a 3 speed?
Every 10 years?
I'm curious what people think about the premise implied in the
basenote: Bicycle choices are a matter of marketing.
I thought that we used what was required. (except for the Jersey Pros)

Sure, tell me about Campy's up market groupos that people
"Need" for the job at hand. What is it, $350 for a set of brakes now ?
Oh, not only Campy, try Shimano, Sun Tour, etc. too. The only
people I can think of right now who still seem to make pretty good
stuff for reasonable prices is Simplex - but they are out of (US)
fashion right now and they don't seem to have been keeping up with the
clickety-click-shifty-stuff, though races are still won in Europe by
people using their stuff. Oh, add Huret for some good touring stuff.

1110.17 | TO EACH HIS OWN | WMOIS::C_GIROUARD | | Thu Apr 20 1989 07:21 | 33 |
| Campy, Dura Ace, Mavic, etc... It's all good stuff and fits the
purpose. "Pricey" - you bet. I'll always be the first to complain
about gruppos and automobiles! The bottom line is IT IS quality
stuff for SERIOUS sportsters. The cheaper stuff won't hold up to
the miles cranked on and the replacement/repair cost might cause
a wash over a couple of years anyway.
I run a Chorus gruppo right now and hope to upgrade (a piece at
a time) to C Record over the winter. I made my decisions by talking
with people who have experience and doing research. I didn't get
any ideas from TV. In fact, Campy is low key in the way advertising
(I think). Pick up a cycling magazine. They advertise as much as
the clothing outfits do.
By no means am I a CAT I racer, nor I am a technical expert. I love
my gruppo and like a million other people do not mind going the
extra yard for what they feel is the best. The very worst feeling
in the world is getting home with something that you've saved a
few buck on and then hating it. Not for me. I'll save my nickels
and dimes and wait before I'll sacrifice.
These companies are tried and true. I don't hear any complaints,
to speak of. I agree with you....are these pieces of alloy worth
the price tag? Probably not. But, ye ole' saying goes, "it's the
only game in town." You can either sit out or play.
Wow! Did I go into a "lecture frenzy" or what? Sorry.
By the way, I wouldn't mind a little support on this one from you
other fanatics out there. I feel like I'm gonna get killed with
this one!

| RE: .-1
We may be diverging a bit from the theme of this note... but
ok, briefly, I don't think of myself as an equipment fanatic
(haven't looked into aero spokes, for example, although I do
have an aero seatpost now), but I am now running C-Record
components, mostly, on my new bike, and SLX tubing - mostly
because they function well over the long haul (that is, years
of miles), and make each mile a bit more of a pleasure.
It's amazing how seemingly small compromises in quality,
durability, functioning start to loom large when you ride long
or far enough. Does that justify the price? .-1 phrased it
pretty well.

| "The very worst feeling in the world is getting home with something

I think the worst feeling in the world is saving your money to buy
something which is somehow touted as "the best" and finding that
it just does not last or that the maintenance on it is so touchy
that you cannot fix it yourself.
Campy super record and C-record headsets are good exampes as far as
I'm concerned, they become indexed too easily. C-record shifters
are another. Campy indexed shifters don't have a good reputation
though they might do in friction mode.
I have a frame that won't accept a Dura-ace 7 speed shifter on
the left side because the braze-on is about a thread short, so it
has a Dura-Ace six speed shifter on the left and a 7 on the right
(what's the difference it's only a front derailleur, you say? one's
Grey and the other's silver, that's what. But using it mismatched
is my personal satisfaction at being dissatissfied at the builder, I
could never get a Campy drive train to work on the bike anyway.)
I have only had one Campy hub ever get dirty. It was my 50th anniv
hub and only went 200 miles before it had to be overhauled. Usually
they are great hubs.
No, there's stuff that works and stuff that doesn't but name alone
does not imply quality.

For most people, something less than the manufacturers top-of-the-line
will serve adequetely. I think Shimano and Sun Tour do a good job of
supplying components for this market. If you have to have the best in
anything you're going to pay top $, no matter what it is. Try buying
something like top quality darts - you'll pay an arm and a leg for what
you get. Or buy some top notch tools like Snap-on - for my use
something like Craftsman will do at 1/3 the price. There will always be
a market for overpriced top quality stuff. Some of the price is quality
driven, most of it is hype. You have to decide if you will go out on a
limb and use something less fashionable.
On the subject of Simplex - I have some Simplex "Super LJ's" that I
picked up a few years ago for use on my European but absolutely nothing
Italian bike. The quality was top-notch. The price was reasonable, but
only because I was "in the business" and bought them from a wholesaler
who was going bankrupt. At retail, the prices were comparable to
other top-notch non-Campy equipment.
