On many sites, when you log in there will be a little box that says "Remember me on this site" that you can click on to check.  From then on, when you open the site you should be already logged in if you are on the same computer.  Your computer has to allow "cookies" to use this feature.

The simplest answer is to build a few tool-room models and let a bunch of rider try them out.  That will tell you far more about the practicality and desirability then the opinions of a bunch of Internet posters who have never seen or used it.  The video tells us nearly nothing.

There never seems to be a Subway when I need one, though!
You must ride is some very remote areas.  Those things are EVERYWHERE.

I actually expected most of the resistance to be from those who know other expanding chainring devices have not succeeded.  I think the advantages of mine over predecessors is its simplicity, which leads to it being lightweight and inexpensive to produce, and that I have designed it to be interchangable with (or as easily installed as) other components.
I will warn you to have the initial trial and production products made by a company that really knows what it is doing.   Even if the concept is practical, nothing will kill a product faster than a series of breakages and early mechanical failures from manufacturing defects.

I saw the report on your product on Bike Rumors today so it seems you are really not a troll.  I agree that the rotational feel is going to be very lumpy and, indeed, the video clip shows the pedaling action to be almost a ratchet.  I also wonder about keeping the chain on the "chainwheel" teeth since it is unsupported so many places in the rotation.   I think a lot of real world testing will have to be done to show the concept is viable or to conclude it was just another of the many "new and improved" bicycle transmission ideas that didn't work.

I don't know if you have had any responses at your web site but I'm very reluctant to click on a link from someone I don't know and who has no history or former presence here.

The most untrustworthy statement you ever receive is, as you reach the top of a really tough climb; "it's all downhill from here".

Big dollar shoes are not necessarily a necessity on a bike tour.

On the Nashbar website they have six shoes which take SPD cleats for $29.99 or less.  Before using a 20% off coupon Nashbar frequently has.  On the Amazon site the Crocs shoes are about $25-30.  These are official Croc brand shoes so they might be much more than the copy shoes sold in flea markets.  $30 or less for a pair of shoes does not meet my definition of "Big dollar shoes".  All of the $29.99 or less Nashbar bike shoes looked like sneakers so I would guess they are comfortable.
Big dollar bike shoes are as much a fashion accessory as a necessity and are aimed at competitive riders where weight and great stiffness are important. 

There are plenty of well made, comfortable and fully functional road and MTB type shoes by well known manufacturers available in the $100 or less range, sometimes much less if having the latest color or "style" and the most advanced technology aren't issues.

Australia or New Zealand.  January is summer there.

Gear Talk / Re: chain ring sizing
« on: November 05, 2014, 06:27:30 pm »
Agree that your "expert" need more and better information.  I've had several bikes geared 52/42/26 and 53/42/26 and 50/39/26 and they all shift well and reliably.

Edit to add an additional comment:  There is a possible problem with a huge chainring difference.  The top run of the chain can drag on the tail of the front drailleur in the small small combinations so you won't be able to use them, at least not quietly.   No loss as there is no reason to use the granny ring with the smallest few cogs anyway.

OK, but I never saw anything of even close to those bikes in any of my local Walmarts.  Also, the bike to OP linked to had a sale price of $180 while the bikes you linked to have prices of $360 to $560 which are in the realm of LBS bikes.  They are different animals entirely.   I don't hold much hope for really decent components on that particular one.

I'll give an opinion on the bike.  What everyone else has said should be considered.  This bike does not appear to be setup for touring/carrying baggage.  There does not appear to be any way to mount racks.  The brakes are sidepull calipers.  They will not be able to fit wide tires.  Anything wider than 28mm likely will not fit.  The shifters are mountain bike shifters mounted on top of the handlebars on either side of the stem.  This does not seem like a good way to shift a road bicycle.  Gearing seems OK.  Triple crankset with at least a medium sized 7 speed cogset in back.  Probably low enough gears if you do not run into anything real steep.  You would need to be a pretty good bike mechanic to grease and tune the bike after you buy it.  And be able to true and build wheels.  Assembly is probably not good.  I think you would be better off finding a used bike more suitable to touring.  You probably need to learn more about bike mechanics.
Everything you mention is correct but it could be summed up in one word: Walmart

I'm trying to to stay as inexpensive as possible.
When trying to use a non-touring bike for touring, it's usually best to consider using a trailer rather than panniers.
This bike cost $180 all-up and the OP is trying to minimize his cost.  Any usable trailer will cost way more than the entire bike.

Just did a quick check and see that the ACA described the GDMBR as:
"The big, bad granddaddy of epic mountain bike routes. 2,700 miles of primarily jeep roads (with a dash of pavement and singletrack)"
That sounds like what the GS and KLR were designed for.
If that's a good description and the single track is both a "dash" and not too tightly wooded or hemmed in by rock walls, then the 1200GS is a suitable machine.

It would be interesting to know the type of motorcycles the above posters saw on the GDMBR.  I suspect most were 250 to 400 cc single cylinder relatively light trail or dual purpose bikes.

The BMW 1200GS you ask about is a very large, very heavy motorcycle of the type called an "Adventure" motorcycle and mainly intended for dirt roads and similar, not single track trails.  Along with it's legality you might try to determine how suitable that particular motorcycle is.
