I have a Surly Disk Trucker with 48-36-26 chainring and 11-36 cassette. 

Comment on crankset.  Your crank will almost certainly take a 24 tooth inner chainring.  74 mm bolt circle diameter.  So you could change the 26 ring for a 24 tooth ring easily.  $15 and 15 minutes.  Little bit lower low gear.  Probably won't make much if any difference.  But it will be the lowest you can get with your current equipment.
His crank may be one of Shimano's "Trekking" cranks and, if so, would have 104/64 BCDs and take a 22T granny chainring.   22x36 with 700c wheels is 16.5 gear inches and you can't reasonably get any lower.

Let us know how those 28 spoke wheels hold up. There was previously a lot of discussion about them on another forum.
Yes, I remember that rather heated thread that didn't resolve anything. 

I expect that a rider who takes a very small frame is going to be light enough not to stress even a 28 spoke wheel unless they wildly overload the bike with touring gear.  The 920 comes with 29-2.0 (700c-50) tires and coupled with rims that are modestly deep section should make those wheels adequately sturdy.

Down tube shifters are simple and weigh less than any other kind of shifter.
Not to get too far into "weight weeneism" here but, while the downtube lever themselves weigh less than other shifter types, you have to add the weight of the brake levers to get a fair comparison.  STI's, Ergo's and the Gevenalle shifters include the brake levers in their weight claims.

If you do enough reading you will find this is one of the more contentious issues among bike tourists with both sides eagerly (and sometimes heatedly) defending why their choice is better.  It's in the Ford vs Chevy and Shimano vs Campy style of argument.

Gear Talk / Re: Wheels without spokes?
« on: April 04, 2016, 07:47:52 pm »
Something has to connect the rim of the wheel to the hub and, thus far for bicycles, individual spokes are the lightest, strongest, most durable, most stable and least expensive method.  If weight were absolutely no object and side winds could be ignored, you could make a solid steel or aluminum wheel like automobiles use.  A solid carbon disc wheel is available but limited to time trials and triathlons and rear wheel use only due to cost and side wind sensitivity.

LOTS of downtube shifting here in Madison WI and LOTS of manual transmission cars Russ. Jetta especially sells lots of them without having to special order them.
I'm with Russ on this one.  Maybe in very flat areas downtube shifters and manual transmissions are a bit more common but nowhere else.   I think you have seen a few of both and generalized that they are far more common than they really are.

Most newer cars aren't even available with a manual transmission and how many new bikes are available with downtube shifters? 

Yeah, VW really shot themselves in the foot but that's a discussion for a different time and place.

You can buy a "floater" insurance for nearly anything with the premium, obviously, dependent on the value you declare.

I wanted my touring bike to have 700c tires and with the Surly Truckers to get the 700c tires they start at 56cm, nothing smaller.  I could of looked at other bikes but I chose not to as I wanted the trucker.
We've had this discussion here before and several of us recommended not compromising the frame size for your unnecessary insistence on 700c wheels.  Too late now and I'm sure the bike you have will be adequate.

Thanks.  Yep, Its a Zefal HPX Classic Aluminum Pump.  I bought mine from eBay, but there are other places to buy it from.  I saw them on www.chainreactioncycles.com for around $28.
I bought mine back in the late '80's before they were called "Classic" and were just standard frame pumps.  Still works but is so heavy that I never use it.

The bike your looking at has a suspension fork if I'm correct. I'm curious to see if anyone has thoughts on that for a touring bike.
The OP is planning on riding the "GDMB" (Great Divide Mountain Bike) route which is an off-road route and a suspended mountain bike, or at least  a suspension fork is highly recommended.  This is not a road tour and a standard road touring bike is not recommended.

To the OP: The bike seems suitable.  The frame appears to have mounting points for a rear rack but be sure the one you buy will work with disc brakes.  There seems to be no provisions for a front rack so, if you are really going to be self-contained at times, plan to travel light.

Old Man Mountain ( http://www.oldmanmountain.com/SFNT.html ) lists front racks for bikes with disc brakes.  They should have what you need.

Gear Talk / Re: Shimano Hollowtech experience anyone?

Let me say something about how 'improvements' come to market........NB No discussion of whether it's a better product for the average Joe It all boils down to making the most money

I've no idea whether Shimano operates like this but over a lifetime in manufacturing I have sat in similar meetings.
I think you are too cynical about how component changes occur.  A lot of the changes are driven by performance rider's constant demands for the holy grails of "stiffer and lighter" and the new designs provide both of those.  Touring riders are not that concerned but they are a tiny portion of the market anyway. 

As to just making changes because the machinery is worn out, note that Shimano still makes both square taper and Octalink bottom bracketrs despite the fact that the vast majority of the OEM market has made them obsolete.

Early failures on Hollowtech II bottom brackets can be caused by poorly faced, out-of-alignment bottom bracket shells.  If those reporting the early failures have badly aligned frames, it would explain a lot as no bearing will tolerate much of that.

I've got Hollowtech II bottom brackets on two bikes with over 10,000 miles on each and they are still in excellent condition.  I don't know who told you about 2,000 mile failures  but that seems absurd unless they criminally abused their bikes.
