CRANK LENGTH
See: http://www.mountain-bike-world.com/mountain-bike-sizing
Your crank length should be 18.5% times the distance from the top of your femur to the floor (in bare feet). The top of your femur is 5 – 6” (12 – 15cm) below your hip bone and it moves rearwards when you lift your knee. A quick way to work this out is to measure from your hip to the floor (in bare feet). Take this length and subtract 5 – 6″ (5″ if you are shorter, 6″ if you are taller). Then multiply this distance by 0.185 (18.5%). The resulting value should be your crank length.

A super-compact double with a 46 and 30 is an option. Here are two sources;

sure it's possible. Here is one crank that will do the job: VO Polyvalent Crankset - Cranksets - Components
A 46-30 is a smart choice for hilly terrain if not racing.
TA copies are also good:
Grand Cru 50.4 BCD Crankset MK II - Cranksets - Components
The Sugino OX601D is expensive but you can really tweak the chain rings on this thing:
Sugino OX601D Cranks Arms w/BB Cups
I think I'd go for the 46-30 VO copy of a TA crank or get a triple.
Another option. shopping fans, White's Variable Bolt circle crank and Compass cycles Singer replica cranks and the old TA cyclo tourist ones, each have small bolt circles The VBC machines their outer chainrings with a slot in all 5 arms and has a custom machined bolt set to fit in that slot. Clever USA Manufacturing .
Some of the common front cranksets available for touring bicycles include:
Compact double: 50/34
Road triple: 50/39/30
Touring triple: 48/36/26
Expedition triple: 44/32/22
Mountain triple: 42/32/22
Currenlty I'm runinng a TA Carmina with 30/44 rings and a 12-36 10spd in the rear. I have a second wheelset with 11-32 on it.
(I also have in the box 30/42 or 32/46 or 32/48 or 34/50 rings... as needed - but haven't changed from the 30-44 in while.)
I generally ride in the 'big' ring... but will drop to the small ring for the steep stuff, or when carrying gear.

With the introduction of the SRAM Apex came the popularization of mountain bike cassettes on road bikes. If you want to see gearing negatives such as gaps in the ratios and gear duplication, put a wide range cassette with a multiple chainring. You will get both of those negatives.

Praxis Sub-Compact Cranksets (48-32t)
FSA Adventure Sub-Compact Cranksets (46-30t)
Middleburn RS8 X-Type Super Compact Cranksets (46-30t)
Engin Cycles Spider + SRAM Road Crankset (46-30t)
Sugino Compact Plus Cranksets (46-30t)
While Sugino only makes the CP74S 10/11s chainrings down to 30t, many people have been using the 'Classic Standard' inner chainrings which are available down to 24t. I generally don't recommend more than an 18t gap between chainrings, so 44-26t seems to be a decent setup.
Have equipped my new bike with 11-42 Shimano 11 speed cassette and Sugino OX901D 26/44 crankset. Provides 18 to 108 gear inches with plenty of half steps. Use the 44 most of the time but have the 28 when it gets steep. Works very well. Just as happy to run this as the wide range triple I previously had.

White Industries VBC Cranksets (40-24t)
The White Industries VBC cranks have a narrow 150mm q-factor and can operate with a 24 tooth difference between chainrings; although I’d recommend a 16-20 tooth difference so that you don’t exceed the capacity of your road rear derailleur. Inner rings start at 24t and go up in even increments. There is both a BB30/PF30 model and a square taper model for those with threaded bottom brackets.
Crankset: 40-24, 42-26t
Cassette: 11-34t
Setup Capacity: 39t
Smallest Gear w/ 700×28 Tyres: 18.6 Gear Inches
Note: a braze-on front derailleur mount may not get the derailleur low enough. Band clamps are ideal.

Middleburn RO1 Incy Cranksets (36-20t)
The award for the smallest chainring on a road crankset goes to Middleburn with their 94/58 BCD “Incy” chainring spider (removable). The “Incy” spider offers a small front chainring as low as 20 teeth! That gets your low gear right down to 17 gear inches. The RO1 cranks are for threaded BB bikes only – sorry press-fit crew.
Crankset: 36-20t, 38-22t, 40-24t, 42-26t, 44-28t
Cassette: 11-34t
Setup Capacity: 39t
Smallest Gear w/ 700×28 Tyres: 15.5 Gear Inches
Maximum Gradient (90kg/200w/80rpm): 12.6%
Note: a braze-on front derailleur mount may not get the derailleur low enough. Band clamps are ideal.
