General Discussion / Re: Potential Resale Value
« on: September 02, 2009, 10:22:38 pm »
Not to mention the whole task of finding a dealer that you trust and ordering a bike that is your size.  Here, a 520 is around $1200.  Unless you can stay for free with friends, what are the costs of staying in a hotel while you wait for a dealer to get a 520 and build it up.
This brings up an important point, if you do plan to buy the bike after you get to the US, you MUST arrange for it well in advance.  Contact dealers and find one that will have exactly the bike you want, in the size you need and equipped as you want BEFORE you arrive.   You can pay by credit card to assure the dealer you are serious but be certain the bike is accounted for and in stock before you arrive. 

Do not arrive here cold expecting to buy what you want just by walking into a couple of dealers at the last minute.

About the only advice you can rely on is to pick your companions VERY carefully.  Even otherwise lifelong friends can be very incompatible after days or weeks of close confinement with each other.

When I read the AC magazine's "Companions Wanted"  list every month I always wonder how those requests work out.  They are asking complete strangers to join them for an extended tour.  Talk about a crap shoot!

There is a cheap way to create "bifocals" from single vision glasses or non-prescription glasses and sunglasses.  These are stick-on flexible plastic patches that provide a reading glass area that shouldn't interfer with the regular distance vision portion of the glasses.

I've seen them at most Walgreens Drug stores in the reading glass display and they are about $10/pair.  Apparently Wal-Mart sells them too.  Well worth trying.  And, no, I don't have any interest, commercial or otherwise, in the company.

Generally used bikes lose a lot of their initial value very rapidly unless they are of great historical interest or can be shown to have been ridden by a very famous person. (I assume Lance's 2005 TdF winning bike is still worth a lot of money even used. :) )  Those owned by us ordinary folks aren't worth much.

You would be lucky to get 50% of the new cost back and that would require finding a willing buyer which will take some time.  Look on various Craigs List or E-bay sites to get a feel for what used touring bikes are going for. Unless you have absolutely no need for it back home, I'd ship it back after the trip.

I expect AC has to balance legability with portability.  If the maps were much larger, they would be too awkward to fit in any handlebar bag holder or would cover such a small distance the number of sheets would be excessive.

I used hear that you replaced the chain and cluster together, and the rings every 3rd chain.
No, you change chainrings when they are worn out and not shifting properly. 

General Discussion / Re: Why SPD pedals?
« on: August 29, 2009, 10:13:34 am »
Shimano did not license the SPD system to anyone.  It was invented in the early 1990s.  Its patent expired a few years later.  Then lots of Taiwanese Chinese companies started making copies of it.
If the SPD design was invented in the early 1990's, the patent wouldn't have expired until 17 years after it was granted or 2007 at the earliest.

If the design was patented in 1995 or later, the patent would still be in force as the term was changed to 20 years from the filing date.

The only possible way the Taiwanese, etc. could have legally copied the exact design is if it was patented in the early 1980's but not commercialized until much later.

I put more than 20k on my recumbent's bottom bracket and the cranks  have 34k on them. The chainrings have been replaced three times; rear cassette twice; five chains, maybe six.

I do have to ask why you changed your chainrings that often?  My experience is that under normal road use, chainrings last at least 20,000 miles and often myuch more.  I've gotten 30,000+ miles on several Shimano road cranks chainring sets and they still shifted cleanly and there was no chain skipping and, no I don't change chains all that often either.

The only truly worn out chainrings I've seen were on my son-in-laws bike.  He is a racer and very strong but it still took him 25,000 miles to wear them to the obvious replacement point.

There are no regular pedals of any kind, road or mountain. Not even platforms or traps are regular any more.
SPD is a commonly used term that describes a more or less universally compatible cleat/pedal interface that Shimano has licensed to many mfrs. SPD is said to stand for Shimano Pedal Device but that's oepn for conjecture and argument.

For the record, "SPD" originally stood for "Shimano Pedaling Dynamics" and is a Shimano trademark.  You are correct that SPD has pretty much become a generic term for MTB-type clipless pedals whether made by Shimano, Look, Time, Wellgo or anyone else.  I'm sure Shimano's lawyers are busy defending the trademark. 

Shimano also applied the SPD term to their road pedals but they never dominated the market the way their MTB pedals do so it's not as much a catch-all term the way it is in the MTB world.

2500 miles is still brand new for any decent crank, chainrings and bottom bracket unless the bike is ridden exclusively in harsh off-road conditions.  Are you experiencing any symptoms that indicate something is wrong?

I have never tried SPDs.
And what are we to do with this information?

Personally, I think the Shimano road SPD pedals are a pain because the cleat can only mount one one side,  and the cleat is incompatible with Shimano mountain pedals.

Shimano's current road pedals, the SPD-SL series, are pretty much "Look-alikes".  They take a very similar 3-bolt cleat, are one sided and a pain to walk in.  The MTB-type SPD are the only ones to consider for touring applications where being able to walk is a requirement.

That's because they're used so much on mountain bikes.  They're not used as much on road bikes, but I don't know which type is most common on road bikes.  There are too many.
That's not correct.  SPD pedals aren't used by road racers or by very serious performance riders but they are widely used by fitness, organized ride, charity ride and touring riders.  Go to any large organized ride or supported tour and do a pedal census.  SPDs will be in the majority.

Are you asking about SPD as the specific Shimmano clip-less pedal design or "SPD" as a generic for clipless pedals by any of numerous manufacturers?

Shimano's own pedals are reasonably priced, available from nearly any LBS or internet/mailorder dealer, well made, durable, have good entry/exit adjusability, good retention and are easy to find replacement cleats for.

One thing that stood out immediately, you haven't checked your tire pressure is almost two months?  No wonder the bike feels sluggish.  Bike tires aren't car tires.  Pump them up at least once a week.
