650b Croix De Fer - Congratulations, it's an apple.

I'm definitely not going round the world, or anywhere truly remote.

The build and use will be closer to:

(maybe not so much skidding)

As I say, I'm not 100% settled on the Disc Trucker, but it hit a good sweet spot between affordability, fit, and geometry.

Croix De Fer with a replacement fork might actually (probably) work a little better, albeit for a little more cash so that warrants more consideration.

From the Surly site:

Can I run either 26" OR 700c wheels on my Long Haul Trucker?
No. Each LHT has geometry and braze-on/ brake boss mounts that are specific to the wheel size intended for the frame you purchase. So, if you buy an LHT 26", use 26" wheels. If you bought an LHT intended for use with 700c's, well then use a 700c wheelset. They are NOT interchangeable.

Not sure how that applies to the DT, but I'd assume the same rationale..
