Three is a (remote) chance that I'll have to assemble a new touring rig. I am very pleased by my LHT, but somewhat leaning towards a Disk Trucker.

V-brakes work for me, and i like the idea that spares are available everywhere, and not that likely to be needed anyway. On the downside, it is not trivial to squeeze a "fat" (2.1") between the brakes' jaws.

Disc brakes are said to be more effective... and finding rims suitable for Vs is becoming surprisingly difficult. I apprehend warped rotors (bike will fly several times a year) and noise due to pads not being perfectly aligned.

But tech improves and I may be attached to something definitely obsolete.

What's the current wisdom?

(Familiar with the countless threads on disc vs non-disc. But touring is a different beast, and the market appears to have reached a tipping point)
