General Discussion / Re: Youth tour on bamboo bikes
« on: May 19, 2010, 01:26:20 pm »
I fully agree that building bikes by and for neophyte young riders is a recipe for disaster, or several disasters.  This is further compounded by the concept of bamboo bikes which require some specialized technology to build anyway.  Noble idea but wholly impractical.

If you are in Pittsburgh, there is an organization in the East End called "Freeride".  They have bike maintainance classes and teach people how to build up a bike for themselves and keep the bike afterwards.  If you can get your kids into something like this they will not only have bikes but know how to keep them going.

Gear Talk / Re: How to remove keyed steering tube sleeves?
« on: May 18, 2010, 09:57:13 am »
I don't know what you mean by a "keyed steering tube".  Based on the photo and description on the REI web site, the Safari appears to have a very conventional threadless steerer/headset/stem arrangement. 

Remove the top cap bolt and cap, loosen the stem clamp bolt and the stem and bars should slide off as a unit.  The "sleeve" over the steerer tube is just a spacer.  With the bars and stem off, the spacer will slide off by hand.

You don't have to buy a gallon of white gas.  As you noted, the MSA will burn almost anything and anything includes unleaded gasoline or kerosene.  You can get one or both at any gas station you pass on the road and only pay for what you need.  If you catch someone filling their car, you might even get it for free for the small amount you need. 

Canisters are specialty items and there are several different and non-interchangable types.  Canister stoves are simpler to use but the canisters can be hard to find unless you have access to a major backpacking/outdoor store like an REI.  These aren't going to be found in small towns.

Should that say, "buy several replacements"?
Yes, it should have, and if I could type (or proofread) it would have. :)

I personally would never buy a car-branded bike.
+1  These bikes are chosen for image, not bicycling quality and are usually low end items.  Buy a bicycle sold as a bicycle, not as a trinket to accompany a car.

General Discussion / Re: How Realistic is 125 miles daily mileage?
« on: May 13, 2010, 10:24:03 am »
According to Mapquest, the distance from Astoria to LA is 1051 miles by the most direct route.  I assume using roads open to bicycles (i.e. not Interstate 5) will make the distance at least this long or longer.  So you are planning on riding 8 or 9 125-mile day in a row. 

Riding 200 miles in one day is admirable but it's not the same as that many back-to-back 125 mile rides.  This sounds VERY ambitious.

I'm really confused.  How do couplers increase the likelihood of getting water in the down tube?
If the threads are properly greased, they don't. 

Another vote for the S&S couplers.  I have a CoMotion single factory fitted with them and they are a perfect addition to a travel bike.  No downside at all except cost and a very minor weight penalty.  You do have to check them for tightness every so often but that's no worse than checking that your brakes work before a ride.

As to a retrofit, of course Co-motion recommends you buy a factory-fit frame, they make them and don't do retrofits.  I've also heard very good things about Bilenky's retrofits but they aren't cheap.

)....and so he's comfortable on this saddle....
That's your answer right there.   Saddles are the most personal item on any bike and once you have one that works, but several replacements because you can be certain they will go out of production or be "improved" by the manufacturer.

I just looked at it on Trek's website and I see they're still using 9-speed, which I like because 9-speed chains and cassettes are far cheaper and last longer than than 10-speed.
They are probably using 9-speed because the largest cog Shimano offers on their 10-speed cassettes is a 28T.  To get the more common touring large cog of 32 or 34T you have to use an MTB cassette and they are only available in 9-speed.

My daughter recently moved from the US to Germany and had the same problem.  The Pharmacist in Germany couldn't legally fill her US prescription and she had to get a local MD to issue one.  The German Dr. did so with no problems but the prescription had to be local to be acceptable.

General Discussion / Re: Cycle lane or another sad joke
« on: March 02, 2010, 11:04:15 pm »
And then there is Chicago, with it's "bicycle friendly" Mayor.  

Many main streets there have bike lanes.  However, the lay-out is; a parking lane against the curb, then a bike lane on the traffic side of the parking lane, then the car/truck/bus lane.  So, every time a car pulls into or out of a parking spot, they cross directly over the bike lane.  Most drivers do it with out even a glance to see if there is a bicycle there.  Then, of course, at every intersection any car turning right also cuts across the bike lane.

Another example of bike lanes designed by those who don't ride and who will never understand the needs of those who do.

General Discussion / Re: Bar end shifters
« on: March 02, 2010, 10:52:20 pm »
I've ridden with both types and the convenience and accessibility of STI/Ergo integrated "brifters" is so much better than barends that there is no comparison in my experience.  The hillier the terrain, the bigger the advantage brifters have.  You can shift brifters while standing and barends are nearly impossible to reach from that position.

Barends are less likely to give mechanical problems.  They aren't immune and brifters have gotten very reliable over the past few years but barends do have friction as a fall back option.  They are also MUCH cheaper so manufacturers will use them to reduce costs if possible.

BTW, there is one other option; Kelly Take Offs.  These are brackets that fasten under standard brake levers and mount downtube shifters just inboard of the brake levers.  They put the levers in reach of your thumbs while riding on the hoods and are nearly (but not quite) as convenient as brifters.  Since downtube levers all have a friction option, you have that fall-back too. They sell for $50 to $70 and use any model or "speed" downtube shifters so the entire thing is much less than any brifter.   Here is a reference:  http://kellybike.com/1st_rrwhatnot_archive1.html

I have a set of Take Offs on one bike and I'm quire fond of them  They are far better than barend or regular downtube shifters at a fraction the cost of brifters.

Harris Cyclery sells a portable mini-lockring tool that does what you want, it allows you to remove the lockring while the wheel is on the bike with no other tool.  Here is the URL reference:

http://www.sheldonbrown.com/harris/stein-mini-lock/

Here is a reference for a DIY tool that does the same thing but, read the caveats before using it.  Used incorrectly or if the lockring is very tight it can damage your frame.

If your choices are either Charlston or Savannah, then Charleston is the hands-down winner.

FWIW, I understand Shimano is going to 10-speed for their MTB groups for 2011.
