The Sterling is no longer made and the Nomad has taken over its role.
Perhaps the Nomad "X" is the Sterling's spiritual successor?
Remarkably light weights for your touring kit, Bob; well done! You're absolutely correct; if you have the capacity you will fill it, and
very little gear is actually needed, as I am finding out with my SOL Kit for casual/unexpected camping: Bivy tent/footprint, lightweight down bag good to freezing, pad, meths stove and fuel, two nesting alu cups with lid, and a telescoping spoon. -- done! Just add some dehydrated soups, some dried meat, and several energy bars, and I'm set for back-to-back 300km days and local exploration at the midpoint. All fits in my rack-top pack and on my rear rack. Rain gear, tights, longsleeve wool jersey, wind jacket, and a hat fold nicely into the HB bag so I'm set for 3-seasons camping use at reasonable elevations, the Nomad still providing go-anywhere access on logging roads and such.
That said, I sure seem to find myself carrying more on longer trips (my chair, for example!)
The Nomad Mk2 is a heavier bike with a higher weight capacity, but can always be ridden lightly laden, as can any bike. We're fortunate Thorn provide so many choices!
[EDIT:
With Suss forks and some addons the Nomad is gonna cost me 3k, thats a lot of dosh for a bike in my world.
In DanneauxWorld, too! There is also the used market with aftermarket mods like the forks added After for some overall savings, or SJSC discounts on returned/demo/overstock bikes. When making purchases, I try to balance object/item/component/bike cost against trip cost. Less spent on one means more for the other.
A last note...rider weight is a factor in a given bike's overall payload capacity, so if one tends more toward Clydesdale than ectomorph, a frame with greater load capacity can be a real boon.]
All the best,
Dan.
