"A modified form of the "One China" principle known as the "1992 Consensus" is the current policy of both the PRC and ROC governments. Under this consensus, both governments agree that there is only one sovereign state encompassing both mainland China and Taiwan, but disagree about which of the two governments is the legitimate government of this state."

Based on what I used the bike for last year, I am happy with what it is, not what it is marketed as. I compare it to nothing as this was my first touring bike after owning a new road/cross/MTB every year working for Spoke and Wheel Bike Shop. Why did I choose this bike? EP pricing, as I worked for a Trek Dealer. (Not to mention the long term relationship I have had with Trek Bikes. I started riding them in 1996 and have enjoyed all my bikes since then.)
I wouldn't want to go into any serious singletrack or extended climbing off road with this bike loaded down. The gearing is too high and the overall weight of the bike is a bit on the stout side. FS roads and backcountry gravel would be fine though. The majority of my riding has been on the paved side with some back roads and ugly desert road riding thrown in here and there.
Even given the drawbacks, I enjoy this bike. The stability when it's loaded and the precision in steering is what stands out to me. I am a fan of hydraulic disc brakes and these work solidly and have required no maintenance in the 13 months I have owned them. ( I'll probably bleed them before the next big trip just to see what the fluid looks like.) Wheels have been on the truing stand once since I built the bike last March. They haven't required any tweaking. I weigh around 175 and rarely carry more than 40 pounds, so that could be why.
With any product there are going to be good and bad points. Sometimes more of one than the other. Are there better bikes out there? Sure. But this one is mine.
My revelation about not caring what other people say you must have in a touring bike was when I saw a kid from France in Bodega Bay,riding a seriously used Schwinn Continental with the original wheels and components from New York to California and was smiling and having a blast with his thrift store special and borrowed camping gear!
For me, I just want to go ride and tour on my wannabe 920.
See ya on the road....I hope you wave back!

Just curious, where was the Spoke and Wheel shop? I bought my 520 from one.

RE: LHT - here are some older specifications. Maybe still current.
"I got the go ahead to post the stats so here goes:
TT=.8x.5x.8 at 31.8mm
DT=.9x.6x.9 at 31.8mm
ST= 1.2x.6x.9 at 29.8mm at the seat tube and 28.6mm at the bottom
bracket
Stays= .9mm
Fork blades= 1.1mm to 1.4mm tapered
The tubes are not heat treated since it isn't necessary for this
frame."

Good info. But I believe heat treating makes for stronger tubes. My guess that if heat treated this frame could be be stronger at 1/2 the weight. A few $100 would be money well spent.
Thanks for the info!!

Also, the main reason that chromoly tubing gets normalized is that in some applications, you have tons of power being dumped into very thick tubes to heat things up for the weld, and the heating is clumsy and uneven. For thin chromoly tubing like used on bicycles, for most bicycle welding processes if carried out properly, this isn't an issue.
Surly isn't saying it's unnecessary because they're cheapskates building glorified department store frames, it's because they know what their welding processes are and the implications with regards to the tubing they're using.
edit: But we're probably talking about heat-treating from the manufacturer, not post-fabrication treatment. In that case, depending on the specifics, it's possible that a little weight could be saved... without very substantial changes to the frame's design and construction, we're probably looking on the order of a few ounces tops, not several pounds.

Not clear whether this would reduce weight by 30% or 35%, however.
How much $ would make it well worth spending to get heat treated? What benefit do you think is derived?

This thread is like a festering sewer with nowhere to go but down. Adios!
And I must warn you gentlemen, bringing baggage from one thread into another is trolling and harassment.
