Why would you want anti-lock brakes?
Many times they only way to navigate a corner
when you are going fast on a trail is to lock up the rear and swing the

One possible application of powerful brakes is on if you want to 
be able to brake for extended periods with a light touch on the
levers, e.g., during a long technical single-track mountain 
bike descent. Shimano addressed that desire with their "Servo-wave"
brake levers, and the original Cunningham rollercam brakes
(licensed by Suntour) also did so through the shape of the
cam plate.

   This is absolutely positively not true !!!  A RED LOOK ARC cleat
 is not self-adjusting just because it is rotational.  Although
 the LOOK ARC cleat has a 9 degree angle of rotation, the side to
 side (lateral) positioning of the cleat as well as the angle
 the cleat is positioned on the sole make a MAJOR contribution to 
 the performance of the cleat !!!  The cleat CAN BE positioned in such
 a fashion as to minimize the effect of its rotational charecteristics.
 This in turn may reduce your potential power output and in worst
 cases cause knee and hip injuries over an extended period of time.
 To avoid all of the above I would strongly suggest to anyone 
 who decides to use the LOOK clipless pedal system to get a RAD
 cleat positioning performed at their local high end bike shop.
 This costs about $25 and takes about 1 hour, but is well worth it !!!
 Trust me I speak from experience !!!  The RAD system finds the
 correct neutral positioning of the LOOK cleat so as to take full
 advantage of the cleats rotational characteristics, thus maximizing
 power output and minimizing the possibilty of injuries. 
 When I first bought my RED
 LOOK ARC cleats and Shimano clipless pedals I spent about two
 hours adjusting them until they felt right to me, only having
 to adjust them several more times over the next week.  Well
 after two years of being told that I ride "pigeon-toed" and
 experiencing discomfort in my left knee every once in a while,
 I decided to get "RADded".  I only wish I had done it sooner.
 After getting RADded I noticed a slight yet noticeable power increase
 and have not experienced any knee discomfort since.

Ther I two products that are as you described.  One is called
"anti-scam-cams" which replace the lever mechanism in the QR.
An allen key (or similar device) is used to open and close.

The second product is outlined in the October issue of 
Mountain Biking (or was it MBA?) and are called mudslingers.
They are replacements for the QR and have a special rachet
tool to tighten and loosen the axles.


The anti scam cams run about $10 CDN for three pieces (2 wheels
and a seat).  I think that the mudslingers are considerably
more expensive.

greetings,

Does anyone know if this pedal will take road cleats?

I have a pair of Duegi road shoes and I cannot use them on a Deore XT pedal
since there is not enough clearance between the cleat and the pedal
spindle. There is also a problem with the back of the cleat not engaging
the pedal all the way because the flip tabs are up too high.

What I am looking for is a mountain bike pedal that has the pedal cage
higher than the spindle.

Any suggestions?

thanks in advance

This is not often true.  Performance, for instance, sells bladed spokes
which require no slotting.  I bought some oval spokes from the company
which required no slotting, and they have held up well.

I don't think a person can tell if they do make a difference.  If you're
riding into a headwind at 32 kph with oval spokes, can you tell if you are
getting a, say, 0.3 kph boost from the spokes?  No, you only know that you
are riding at 32 kph.  Theoretically bladed spokes do make a bit of a
difference because round spokes are responsible for a large part of the
bike's aerodynamic drag.  Remember that Laurent Fignon lost a Tour de
France by 8 seconds.  You never know when that extra aero advantage will
pay off.

how are helmet-mounted lights attached and designed?

does the battery mount low, on your belt maybe, and a

To whom do you have to pay tax to? I paied 7.25% (or is it 8.25%) tax in
Texas, then 20% tax to get the bike into Norway. But the shop in Texas
gave me two receipt, one showing the actuall price of the bike and all

the extra super special price ;-).

If it is boxed, it goes as a part of your luggage (I used KLM). As long
as your luggage with your bike included is belowe 60 kg. you should not
pay any extra for the bike. If they as you what it is, just say "Fitness

You are going to have to tell us what brand and model of suspension fork
you installed. That is certainly not normal behavior for Rock Shox or
Manitou. That is, unless the Rock Shox had way too little air pressure or
the Manitou had way too soft a bumper combination... It sounds like the
fork was in a heavily pre-loaded condition. Rock Shox do not pre-load very
little or not at all depending on how they're set up. Manitous pre-load a
little more--around 1/8 - 1/4 inch depending on how you set them up.

I think perhaps you installed an inexpensive Taiwan knock-off?...

Not producing identification might of course have suggested to the
officer that you perhaps had something else to hide and so he might have
taken you in to be booked.

Of course one of the arguments you hear from some motorists for banning
bikes from the road is that, as we don't have operators licencess
(though many perhaps most of us do), the traffic act cannot be enforced 
because 1) violations won't go on our driving record and 2) we will not 
be able to be charged in the first place due to a lack of such a licence.  

Both arguments are specious.  First, one has a driving record wether or 
not one has a licence and that record can be taken into account in 
determining punishment or conditions of parole.  Second, if one could 
only charge those with valid driver's licences then those driving 
automobiles with out or with suspended licence could not be charged, 
while they regularly are (whether appropriately is another question).

Vancouver, British Columbia, proposed (I don't know if it was passed)
that cyclists either show a police officer identification or have their
bicycle impounded until they would produce such or, if charges had been
laid (which was the case invisaged by the bye-law) and if a cyclist
refused to produce ID there or at a later date, at the completion of the 
legal process.  This always seemed a reasonable procedure as it means 
that the police would not be forced to arrest a cyclist in order to issue 
a simple traffic ticket, it would also end the above specious
anti-cyclist argument.

	Well, after my 19-mile ride, I find that a quick sponge bath
with a soapy facecloth in the bathroom and a change of clothes works
quite well.  Of course, a shower would be *nice*, but not strictly
necessary.  This is true even on the most sweltering summer commute,
but on those days I find that I'm wanting the shower more than usual
:-).  Your mileage may vary.  One advantage of the sponge bath is that
it's quicker than a shower.

Because the nose does not react to the absolute level of a smell in
the air, but to change. A new smell is immediately noticed, but
quickly habituated to. Compared to the cyclist, the car driver
experiences a much slower rate of change of smells, due to the
buffering effect of the internal volume of the car. That's why
cyclists experience smells more keenly than car drivers. It is also
why cyclists experience smells more keenly then pedestrians -- a
faster rate of change. And it is why motorcyclists experience smells
the sharpest of all -- a higher rate of travel through the fume level
gradients in the air.

In cars one can increase the buffering effect by closing all the
windows. This has led most car drivers to suppose (well, we all know
how stupid they are :-) that closing the windows is protecting them
from fumes, instead of simply making them harder to smell. It also
lowers the fresh air intake points to a layer with higher fume
concentrations. So closing the windows makes the air smell better
while actually raising the level of fumes.

The buffering effect of the car's volume also means that a simple
protective strategy against local fumes which is available to
pedestrians, cyclists, and motorcyclists, is not available to car
drivers: holding one's breath until the smell has passed. It doesn't
work for the car driver because the buffering effect of the car's
volume has dramatically reduced the correspondence between perceived
smell and actual amount of fumes.
