A bit racy for me with those red highlightsHere’s my Thorn Raven (picture taken on my ride this morning). 10 years old, 25,000 miles. The gear shifter numbers all very clear. It’s had 2 chains. I’ve changed the tyres once. It’s lighter than the Nomad and slightly faster. It’s a nice do it all bike.

It is not a mountain bike on which you might want to slam up and down the gears at a moment's notice.
Unless I'm missing a trick here, I really can't see very much difference between any of these really expensive heavy duty touring frames based on 26" wheels, and a simple old-school 26" steel MTB! Rack/mudguard mounts are standard, as are bottle cage mounts for at least one, and often two, bottles. A good proportion of the old stuff will also have horizontal dropouts, so are compatible with any hub gear that will fit between the chainstays.
Correct.
But the main difference is in the Rohloff hub itself, which is where the expensive cost comes from.
I get that the hub gear is the main cost thing, and the rest of the bike is almost incidental. What I don't get, given that steel frames have a virtually unlimited lifespan, is why more riders who specifically want a Rohloff don't just source the hub or a hub/wheel and convert an existing derailleur bike with suitable geometry and dropouts.
Interested in this, because there's a difference of opinion (as often) between Thorn and others on dropouts/chain tensioning.It's not just horizontal rear drop outs but having a means to fix a torque plate to prevent the torsional rotation of the hub under load. The torque arm that you sometimes see on the non drive side looks some what inelegant. Also you can use a frame with vertical drop outs but would need to fit an eccentric bottom bracket as a means of tensioning the chain or belt as you cannot move the wheel fore or after in a vertical drop out. You could use a chain tensioner similar to a derailleur, but that then rather defeats the object of the Rohloff hub imho.
