Gear Talk / Re: Computer Install Question on LHT - Placement on Spoke

The shape of the pick up sensor usually dictates where on the fork it must be mounted.  I position the magnet to work with the sensor.
The recent Cateye cyclometers I'm familiar with have pickup mounts that are useable anywhere along the length of the fork blade.

Not me.  It never has occurred to me that a cell phone was an essential safety item.  That may be because I grew up years before they existed. 
Actually my kids grew up before there were cell phones! 

However, I've heard they can be a useful deterrent if you are being hassled by a driver or someone at a restaurant or where ever.  Get out the cell phone and, even if there is no signal, go ahead and dial it. The offender will think you are calling the cops or for help and is more likely to leave you alone.    You can even pretend to be talking to the cops if necessary. 

If there is a signal, really do call 911 if you think you are in any real danger.

The only possible problem is if the magnet and pick-up are mounted very close to the rim.  The linear speed of the magnet past the pick-up can be high enough that the pick-up doesn't catch the signal at high bike speeds.  Some computers are sensitive to this and others aren't.  I usally mount the magnet and pick-up about 1/3 of the way out from the hub or about where the third spoke cross occurs on 32H, 3X wheels.

As the others have noted, the theoretical accuracy is the same no matter how far out the magnet is located.  One pulse per revolution is the same for all points on the spoke.

I believe the original article firet appeared in Forbes magazine. 

Anyway, don't read too much into the numbers.  A very large part of the violent crimes in any city are drug related, either turf wars between competing drug gangs or drug deals gone bad.  The more drugs a city has, the more violent crime it has and the crime mostly (not exclusively of course) effects those related in one way or another to the drugs.

I would think RI would be a good choice. :)

There is one principle to keep in mind with almost any bicycle touring or camping gear:

Light, Cheap, Good

Pick any two.

Also check out Campmor (  They have a wide range of camping, backpacking and bicycle camping gear at very good prices. 

Particularly check their "Super Special Deals" area where name brand gear, but in last years colors, etc, are available at extremely attractive prices.  About two years ago I got a North Face 20 degree rated synthetic sleeping bag that weighs about 3 pounds for $70.from them.   

As noted Eureka and Coleman have low cost but serviceable tents suitable for bike camping use.   Second the recommendation for a good sleeping pad.  Thermarest is the best known name but they tend to be pricey.  Campmor has a house brand version that is slightly heavier but very serviceable and a lot less expensive.

Colt does not list the mass of their products on their Website so I'll guess a WWI replica 45 is about 6 pounds?
The standard full size steel frame 1911 weighs about 37 oz and an alloy frame shortened version gets the weight down to about 25 oz. 

BTW, Colt is pretty much out of the civilian firearms business but there are dozens of makers of the basic 1911 and variouss improved upgraded models.

General Discussion / Re: Best Camera for touring?

The 8 megapixels is adequate, and the newer models go up to 12.
How fast we get spoiled.  It wasn't very long ago that professional level DSLR's didn't have 8 megapixels. I recall seeing a digital back for Hassleblad's that had 11 megapixels, was limited to an ISO of 50 and cost like a new car.  Now point-and-shoots have more. 

Unless you are making photo billboards, the huge megapixel count is irrelevant.

7 megapixels will provide very sharp detailed photographs unless you are making poster size prints. 

I wonder if your problems are with the photographer rather than the camera.  Do you hold the camera steady when you shoot?  Most digital cameras are very small and light and most photographers hold them at arms length to view the LCD screen at the back.  Both these things  make for a very unsteady platform. 

Try mounting your camera on solid tripod and using the self timer to take a few pictures.  That should eliminate camera shake entirely.  Then see if you picture quality improves.  Don't be at all surprised if it does dramatically.  If it still isn't adequate, look for a camera with a better quality lens but more megapixels, by themselves, probably aren't the answer.

Gear Talk / Re: big, wide feet need touring shoes
« on: March 20, 2009, 01:21:07 pm »
MTB shoes do recess the cleats far enough to make walking possible and even rather easy but they were never intended to be hiking boots. 

If you plan to do a lot of walking or hiking on bike tours you should include suitable shoes with your gear.  For that matter, I wouldn't want to spend every waking hour in riding shoes of any kind even if I didn't plan on a lot of off-the-bike walking.

Actually, if they would install more trails going across between rivers, similar to our freeway network, more people would get out of their cars and ride the trails, which would mean that freeway-widening projects could be delayed.  IOW, cyclists  reduce the costs of infrastructure.  We don't increase it.  Realistically, I think all this bill will do is reduce the number of people getting some much-needed exercise.  This bill is not good for Oregon or for other states that might follow.

Rep. Krieger seems to have a chip on his shoulder from cyclists not stopping at stop signs and lights.  Please, everyone, don't give people more fuel to hate us.  Obey the laws.  But I also have to say Krieger is wrong about the intended us of the roads.  It was the League of American Bicyclists that originally pushed for paved roads a hundred years ago; and now that motorists have the paved roads, they want us off the roads (or at least damaging them in a car instead of riding a bike).  It makes no sense.

Ever hear the saying; "The power to tax is the power to destroy."?  Maybe Rep. Krieger is mostly interested in getting bikes off the roads, not in increasing revenue.

Yes, the LAW (as it was then known) was instrumental in getting the roads paved and those roads were then taken over almost exclusively for motor vehicles whose operators resent bicycles. 

However, bicyclists were also the major force behind the first Rail-Trail conversions and on most of the resulting trails, the walkers, skaters, runners, etc., etc. now view bicyclist as dangerous and unwelcome intruders on "their" trails.

The most I ever got out of a $30.00 rear wheel before breaking a spoke was about 3,800 miles. After a spoke breaks, they keep breaking.....

The thirty dollar wheels I use are not good on the back of the bike, but I have not had a broken spoke on a front thirty dollar wheel even on very long tours and rough roads. But of course, after tour I must buy new wheels. I cannot use them over and over again touring like others can on better quality wheels.
Well, I typically get 30,000 or more miles out of a wheel built with Shimano 105 or Ultegra or Campy chorus hubs, DT or Wheelsmith spokes and Mavic CXp-33 rims.  The rear wheel costs about $160 so, since I get nearly 10X the number of miles, my per mile cost is just over half of your $30 wheels and I NEVER break a spoke, the rims eventually crack from brake wear.

There is a saying that; "only a rich man can afford cheap tools."  You must be rich.

The cold and very hig humidity that accompanies the storm may be causing condensation on the inner wall of the tent from your breath or just from the humidity in the air.  When the rain drops hit the cloth, they force the water already on the inside to pop off and it appears the rain went completely through the fabric.
