1572.1 | keep close to the levers... | SHALOT::ELLIS | John Lee Ellis - assembly required | Tue Jun 05 1990 14:15 | 13 |
| Yes, some braking is better than none, but if I can make any
argument it would be, always ride close to the brake-levers
if you are in a situation with limited visibility, prone to
surprises, etc.
You can ride with your hands on *top* of the brake-hoods -
that seems to be feasible ... but I wouldn't have my hands on
the center part of the handlebars in a traffic situation.
As you say, if it's emergency and unexpected, you'll likely
need all the braking power you can get.

| I agree with John. In traffic situation, keep your hands
in the drops, near the levers.
With the new bike, I can brake (not panic stop) adequately
simply using the index finger and middle finger on each hand.

My last bike had the safety levers. As was said
previously, the stopping power of the safety levers is
definitely less than the lowers.
It took one ride to get used to not having the levers
there. Now I feel that I am actually better off not having
them. There are a lot of reasons not to be on the tops of
the bars when braking. Your ability to control the bike is
not quite as good, you can't manuver as fast etc.
I really haven't missed the safety levers at all. I don't
think it is a macho thing at all. I don't feel that there
is any big advantage to having them.

| re: all
My first bike some 18 years ago had levers that were called coasting
brakes - they said nothing about safety nor, looking back, would they
have angthing to do with safety.

1572.5 | Basenoter's musings... | SMURF::PARADIS | Worshipper of Bacchus | Wed Jun 06 1990 13:43 | 30 |
| Thanks for the input so far. Good advice from all, but my central
question remains (mostly) unanswered; maybe I can rephrase it:
If someone were to invent a "perfect" safety lever (i.e.
something that provides just as much braking power as
the regular drop-mounted brake levers), would there be
any reasons NOT to use it?
MILKWY::CRITCHLOW mentions at least one possibility:
> There are a lot of reasons not to be on the tops of

> not quite as good, you can't manuver as fast etc.
I hear ya. However, what I was thinking was that there ARE going
to be times when you're relaxing on top of the bars and something
(dog, car, SOAPBOXer 8-) ) is going to pop out of nowhere and
require that you stop NOW... and having brakes close at hand
would be really nice...
Or are you trying to say that if I'm going fast enough so that
I need THAT much braking power then I should be riding in the
drops anyway... and if I'm going slowly enough to be riding upright
then I should be able to afford the split-second it'll take to
reach the brake levers? (Remember, I AM new at this...)
Thanks for your patience 8-)

Yeah, I guess that is essentially what I am saying. But,
more to the point that I was trying to make, I just plain
don't miss having them. I don't feel less safe. I have yet
to be in a position to have that "split-second" delay make
a difference.
I wonder if the reduced braking power of the safety levers
would wash the effects of the split-second delay anyway?
Putting the ideal case of safety levers that work as well
aside for a moment:
I think that the prevailing message about the levers in
general is (as previously mentioned) that they can lull you
into some dangerous habits. My wife uses the levers almost
exclusively and will not let me take them off. You can be
sure I keep them properly adjusted. There clearly are many
situations where using the lower levers will give more
control. But, since the safety levers are closer they get
used first. Is that bad? Not usually, sometimes though...
Just my perceptions here, :-)

| I for one wouldn't use the levers even if they were in style (read COOL) to
have on your bike. I almost never ride with my hands on the tops of the bars.
I ride with my hands on the brake hoods 85% of the time. These newer aero brake
levers have the most comfortable grips on them and they put me in a position
that is not down on the drops or upright in the wind. As goldie said,"It's just
right." Riding with your hands on the hoods requires only the movement of your
fingers to reach the brake levers. The only time I ride on the tops of the bars
is when I ride up a very steep hill and need to give my diaphragm more room so
I can breath (gasp) easier. No need for brakes then, I'm going too slow for 'em.
Hey Chip, if Campy came out with C-Record safety levers would you get them?

| I am really slow going up hills. Ya know, maybe I ought to
put a set of training (get it, training) wheels on my bike
so if I slow down too much, I won't fall over. I really
get embarrassed when I slow down so much on a hill I
fall over.

are great and I would put some on my TREK if only I had a little
more courage (to ask someone to put them on.) It was a good point
that r.0 made about all the breakthroughs they have made in every
other peice of machinery on bikes why can't they work on this some
more? It isn't macho.
There, that settles this argument!

1572.11 | aero safety | SHALOT::ELLIS | John Lee Ellis - assembly required | Wed Jun 06 1990 21:06 | 14 |
| (a) My first ten-speed (a Motobecane) had safety levers,
and I liked them; every bike after that (including the
Motobecane that replaced it) hasn't, and I haven't missed
them a bit.
(b) In my case, all these tradeoffs are superfluous anyway,
since, if I need to make that really *sudden* stop, I
use the grappling hooks *and* drogue chute that my aero
seatpost has pretty much made necessary. I know I've mentioned
this before, but I think a lot of people buy the aero without
the concommitent responsibility to back it up with state-of-the-art
braking equipment. ;-)

Wow, this is one time I'm glad I ignored the advice in here to get the
aero seatpost! If there is ANYTHING I hate, its having to repack the
damn chute after using it! It is so bloody hard to get it into the
underseat bag!!!!!!!!!!!!!!! :^)
But, I DO like the training wheel idea from the earlier note! I
usually take it as a sign to get off the bike and walk up the hill when
I fall over!

1572.15 | Oooooo, suicide levers!!! | SUSHI::KMACDONALD | Hat floating? It's MUD SEASON! | Fri Jun 08 1990 13:54 | 24 |
| Actually, when I was in the bike biz, we used to call 'em "suicide
levers". Removing them for customers (even if they didn't buy their bike
from us) was one of a number of little jobs we used to do for free. If
we'd've had an aluminum recycling plant nearby, I coulda retired :-).
The primary problems with existing designs are that the lever arm is too
long and introduces too much flex in the system - if you hold the "drop"
lever solid in the non-braking position, you can still flex the suicide
lever enough to touch the bars in some cases!
Also, the little wedge that actually pulls on the Real[tm] lever forces
you to adjust the brakes so that the Real[tm] lever is already partially
compressed, and occasionally I saw bikes where even squeezing the
Real[tm] levers all the way to the bar didn't produce full braking.
Ooops.
I did see a design once that eliminated problem 2, but the quality of
the product was severely lacking and problem 1 was actually worse.
After I got rid of the suicide levers on my only bike that had 'em I
found that I really kinda liked the little mounting pegs (extended brake
pivot pins) and I got used to hooking my thumbs around 'em when riding
over the hoods... long gone now, tho....

Think about driving a car. You have to take your right foot off the
accelerator and move it to the brake. It takes a fraction of a second. You
don't need to drive with your left foot poised over the brake. At least I hope
you don't.
It takes no more time to move your hand from the top to the lever than it does
to move your foot from the gas pedal to the brake pedal.
The hypothetical question was asked, WHAT IF they could make "safety levers"
that were as good as moving to the drop position? If they could then there
would obviously be no reason not to use them. However at this point in time
this is not the case.

Safety levers are a victim of the serious elitist strain that
permeates bicycling. Once an item is branded uncool, all kinds
of reasons are found to not have them, despite the convenience they
may offer. Kickstands have been uncool for years, and snob bikers
used to brag how the first thing they'd do is take them off the
bike and throw them away.
Personally, I'd like to figure out some way to get coaster brakes on
my Cannondale.

RE: .17
I think That you are confusing what you call "elitists" or "snobs"
with people that are concerned with Saftey and the lives of other
cyclists.
These auxiliary brake levers do not give you the capabilities of
the normal brakes nor can you get the control sitting upright with
your hands near the stem that you can bent over with your hands
wider apart on the brakes. When you are sitting upright you have
a high center of gravity. This with the loss of control from having
your hands so close to the stem results in a less stable situation
then when you have a lower center of gravity and better control
from being bent over with you hands on the brakes.
The opposition has little if anything to do with what is cool or
not. If you care to check I bet you'll find that the people who
are opposed to the so called "saftey levers" are advocates of
helmuts and helmuts aren't cool. Just ask any teenager.

1572.21 | GIVE ME A BRAKE! | IOENG::DHART | Vegetarian Extremist | Wed Jun 13 1990 18:44 | 15 |
| RE .17 Coaster brakes? The amount of heat you can dissipate in the
hub of your rear wheel is so insignificant that you would
probably be better off dragging your feet. Coaster brakes
belong on low speed kiddie bikes only. Even there they are
theoreticaly unsafe. What if the kid is flying down a steep
hill at 20+ mph? Brake fade and the resulting disaster is
a fact of life with coaster brakes. Believe me, you are
much better off dissipating that heat with a 26"-27" alloy
rim rotating in the breeze. It is entirely possible to
unglue your tubulars with the amount of heat generated on
a long fast downhill run. Coaster brakes are aptly named
because any serious braking will leave you doing just that,
COASTING!

A panic stop by its nature is just that. It's unforeseen. If I knew
I'd suddenly encounter an obstacle, I'd be on my drops with three
fingers tightly clenched on each lever.
In reality, most people ride bikes for recreation. They like to sit
upright, not crouched, and like to look around. It's annoying when
approaching a traffic light, just when I want to have maximum visibility
and be maximally visible, I have to crouch down to ensure that I can
come to a complete stop. Moreover, if I am going slow on approaching
an intersection, I want to be upright to maintain maximum control of
my vehicle; safety levers which allow me to gently feather the brakes
without coming to a complete halt would allow me to do that.
Something like coaster brakes, which would allow me to keep my hands
on the bars for maximum control, sound like an ideal answer. Not the
mechanics of the brakes, but the application- the ability to use my
feet to help stop me, without leaving the control point of the pedals.
The braking doesn't have to occur in the hub; for all I care, there can
be coaxial disks and calipers in each wheel, with hydraulic anti-lock
assist.
I wouldn't assume that anymore than a small minority of the biking
public is riding around at 20 mph, and for these occasional riders,
anything that will help them to maintain control of their vehicle
is a plus. If the biking elite, including the magazines, had accepted
safety levers, I'm sure bike engineers could have developed really
mechanically effective ones.

The biking elite have designed a bicycle for your style of riding. Its
called the mountain bike. You can sit upright, have both hands on the
handlebars at maximum width for maximum control, and have more braking
power than you need without compromise.

Hi, Larry-
RE: Mountain bikes, that's my point exactly. Mountain bike sales now
make up around 2/3 of all bike sales. This share has grown at the
expense of road bikes. Touring bikes are all but extinct in sales.
Why the growth? Are the buyers suddenly taking off for the outback?
Just as the number of 4X4 buyers who ever take their vehicles off-road
is in the single-digit percentages, I'm sure the number of mountain
bike riders riding bikes into the mountains is similar.
No, the real reason for growth is that the bikes fill a real need-
upright, comfortable position, a certain balanced heft or heaviness for
stability, you can shift without bending over. In other words, three
traits that we were for years lead to believe were undesirable
attributes in a bicyle. Bike riders came out of the closets to welcome
a new breed of bike over which they didn't have to crouch, and yet
could still be socially acceptable by the biking elite.
Anyhow, my real answer is my Schwinn Cantilever Cruiser. I only use
the Cannondale if I'm in a hurry and going far. In other words, the
Schwinn is pure biking; the 'dale is more akin to an automobile. Yes,
I belong to the anti-elite elite.

| You don't need to be on the drops to apply sufficient force on the
brake levers to stop. You can stop just fine with your hands on top of the
levers, you are also upright to see what is going on. Admittadly�you
can apply less force in that position, than on the drops, it's still
more than you get with "safety levers", and you are in a more stable
postion. Usually, if required, you can get down on the drops one hand
at a time and do really forcefull braking. Besides, situations that
require a real "panic stop" should be rare.

| We can solve this argument fairly quickly. As the cycling "elite"
we should solicite some of the more progressive manufacturers, e.g.
Shimano, to develop power disk brakes with anti-locking capability.
The result is more stopping power for the real neophite cycling
community with added control for those emergency applications.
Pretty neat, huh Wally?

You'd think if they can develop a three-spoke fibre wheel,
they could develop a light-weight, reliable, hydraulic
disk brake for bikes. Well, maybe.
(By the way, hydraulic brake systems have been in use
for several years, in the Netherlands, I believe.
Possibly not ready for prime time, though.)

If you want to race order your stead without the disk brake.
If saftey around town is your hot button then pay x dollars
more for safety levers with hydraulic disks (Probably could
use the same technology that exists today on light dirt bikes).
Bottom line is that you get what you pay for!?! Which probably
explains why we haven't seen it yet - no one is willing to pay
for saftey levers that are really safe.

| .25 is right. You can stop more securely by dropping one or two fingers
down from the top of good normal brake levers than you can by using your
whole hand on "safety" levers. Once I've demonstrated this to novice
cyclists, they tend to choose real brakes.
It's conceivable that someone could come up with quality safety levers,
but the cost would be too high for the target market. Mountain bikes
are a great idea for those who are nervous about drop handlebars.
