My derailleur touring bikes have a low gear of 20.7 and 19.2 gear inches, my expedition bike with a Rohloff has a low gear of 16.5 gear inches. I have walked bikes up a lot of hills that were loaded down with camping gear, including the (non-folding) bike with 16.5 gear inches that is shown in the photo after I pushed it up a really tall and steep hill.

My 64 year old knees can't handle the hills that they could three or four decades ago.

i am not questioning your need for, let's set a number for the sake of discussion, 18GI. i question instead that one cannot get enough touring range with SDD and a single up front, avoding a long RD on a 406 wheel. What range does a 45T up front with a 11-36T cogset mounted on SDD afford? 18-109GI. You want 16GI at the bottom to match your Rohloff, with a 40T single up front, you get 16-96GI. Gorgeous touring range.

Now, if you are willing to chance a long RD to fit a double up front, why would you not.just use a 11-42T, 11-46T cogset instead?

I have a 507 wheel on my folding bike, thus the dérailleur hangs a bit higher than a 406. I see no real need to switch to a 40 plus sprocket in the rear, I am running an 11/32 cassette in back with a single 39T chainring. I have a compact double in storage that I had on the bike before the Dual Drive, the existing derailleur would handle both the 11/32 cassette plus the compact double. I probably won't make this change, but I will keep the thought in the back of my mind in case I decide to use the folder on a trip with big hills.

Yeah, i just don't understand, that is, you are not explaining the thought process or rationale for a double up front when demonstrably, with a real example that can be replicated on a 507 wheel, i have shown that SDD with single chainring gives enough touring range. Unless 16-96GI is not wide enough for your touring needs? And when simpler rather than more complex is the name of the touring game.

I sold the SDD precisely because it had excess, unused range, and i was paying for that surplus in weight and complexity.

At last, the majik ten, now I can participate.

A few questions from one new to serious folders. What is ment by cadence? I'm reading numbers like 100, 120, even 140, yet, try as I might, I'm unable to manage much over 70 RPM on the crank!!
I know that I'm out of shape but this is unloaded on a Dahon that even with 26" rubber, feels like a mountain bike with its 21 speeds.

Still trying to figure out which bike I have, it is labeled Mariner but has 26" wheels, a spring seat post, and 21 speeds.

I need to source those tiny allen wrench (socket head) bolts used to center the brakes.
