Is there a production bike with proper touring gears?

I've had my Surly LHTD for a short period of time but I've found the lowest gear with the chain on the middle sprocket up front is so low I can't maintain enough speed to keep the bike upright! Geeze Louise! If it ever accidently gets shifted over to the small sprocket whatt'm I gonna do?! (Yeah, I'm a rank amateur and it shows!)

I guess it depends on just how much contact there is.

If it's rubbing,you don't HAVE to do anything,the problem will fix itself.
On mine,the roller didn't even touch the bottom of the gear.I had to take an 1/8" off the crank post and turn the bolts down about .030 for the roller to bottom out.
That's on an Alivio crank....Maybe better cranks have a smaller post.

Also getting a 21" gear on a double would be impossible. A 26 tooth chainwheel with a 34 tooth cog gives a 21" gear. No doubles, to my knowledge, use an inner ring of 26 teeth. If you used a typical compact double with a 34 tooth inner ring, you'd have to use a 42 tooth cog on the cassette to get a 21" gear. That introduces more problems than a triple crank ever will.

VO sells some set up that way , Now,
back in the 80s I rigged up some Campag and Gippiemme triple parts its a 144 86 bcd crank
I got it as a 36 3rd ring used a <C> 52t GS in the center and
filling the outer spot, a <C> 222 diameter Cross guard ring .

is the contact you guys are talking about because the 20 ring is too close to the middle chainring? Last summer when I changed my 30t to a 26t and had to put some washers between the crank and the 26t so the chain wouldnt hit the bolts past a certain point of chain position at the rear. Moving the 26t out just that 1mm or so fixed the problem.
If i recall, past about mid cassette, the chain began rubbing stuff, the 1mm ish washers werent too thick that the chain could go between the 26t and 39t, but far enough to cure the clearance prob that come with a given chainline past mid cassette.

The 4 mounting boss' on the crank and chainring bolts for the granny gear.
If the boss or chainring bolts are too big,the side plates on the chain hit them before the roller on the chain bottoms on the gear.
The chain doesn't sit down on the gear all the way.

Oh OK right, get it now. So I guess it depends on the shape/design of the mounting bosses and the placement and or bulkiness of the bolts. Thanks.

It is so easy to change gearing, that would be among the least of my concerns. Bike fit and geometry trumps all.

I confess I don't buy bikes; I buy frames and assemble things myself. My last bike was a Salsa Vaya. I put a 20-32-42 crank (94-58) and originally put it together as a 12-32 8 spd. That gave me a nice range 1- to 95 inch range. I then discovered the 12-36 9 spd and converted it to 9. Now I use the 32-36 combination quite a bit (24 in.) but hardly have a need to use the 20 ring, so I suspect I could easily live with the more common 22-32-42 cranks.

You should say "for you". What works for you doesn't work for everyone else.
Also getting a 21" gear on a double would be impossible. A 26 tooth chainwheel with a 34 tooth cog gives a 21" gear. No doubles, to my knowledge, use an inner ring of 26 teeth. If you used a typical compact double with a 34 tooth inner ring, you'd have to use a 42 tooth cog on the cassette to get a 21" gear. That introduces more problems than a triple crank ever will.

Like I said in my original post, that introduces more problems than a triple would ever cause. It leaves a big hole in the middle of the cassette (not a huge problem) and derailer set up is going to be finicky. You can get the same gear range with a triple without all the hassles.

Preaching to the Choir. ... I prefer a bit tighter cassette... my 11-34 has some big gaps in it on the road... on the trail it's not an issue... planning to move to th 11-28 on my touring bike... With the 11-34 I never drop to the 22t up front... I'd rather the occasional granny gear use with the tighter gearing out back
My off road touring bike has a conventional mountain bike triple 16-104 (26in wheels).

No one has to leave it as it comes out of the box ,
though the shops will put it on the sales Floor as they get it.
want different? Ask at the place you get your bikes , takeoffs and Upgrades can be done.
