The bike will be used for commuting that is 50% off road., 40mile round trip in Cornwall. Also touring when I get time. Yes, itís an oval chainring from absoluteBLACK. The frame has bottle bosses filled with bolts.

I do not see a lower bottle cage below the downtube.  If you do not plan to put one on, if the bolt holes are open, I suggest some bolts in the holes to keep out any water or dirt thrown up from the front tire.

Yay! Another drop-'bar Nomad Mk2!  ;D

Still delighted with my 2012 model configured similarly.

Best wishes for happy rides,

Dan.

Now that's a look I haven't seen before on a Nomad. Is that some sort of open saddle on it?

Looking good.
Any specific use for it?  Or is it more a do it all, everyday bike?

Looking at my list of bikes, I realize how many would be considered "obsolete" by current riders.
I consider obsolescence one of those things that can only be decided by the rider, disagreement being pointless, whichever direction you're disagreeing in.
I ride in a group where the variety of bikes has shaped many of my opinions, from those who bought a bike 30+ years ago and see no reason to change, to those who have an idea their bike is tired and in need of replacement every couple of years.  I fall somewhere in the middle, sometimes it's nice to have a change just for the sake of it, though it can turn out to be either an advantage or a mistake depending in part on how clear the objectives are.  One thing for sure, any idea I had that the bike makes the rider, disappeared many years ago, I frequently ride with someone with a pre Rohloff Nomad, they had it when I met them over twenty years ago, apart from a re-paint they've just changed worn out stuff - Club rides, Audax, Challenge rides, a few tours - I've never got to the top of any hill before them :-\

Do whatever makes you happy, I've never seen a report that not doing an oil change better caused an issue, I suspect the requirement for annual or 3,000 miles is already on the cautious side.

Here's what makes me happy:
Flush with 25ml
If it looks dirty flush again with another 25ml
Insert 25ml Oil
Go for a ride
Remove 15ml

Mileages on my hubs are
103,000 (96,000 recorded, 7,000 a very conservative guess for the rest)
48,000 (Though only 7,000 of those by me)
11,000 for the baby of the group

All three had a couple of early oil changes when new, then the regular annual/3,000 mile routine, though I'm not fussed about +/- a month or a few miles.
No problems so far.

I'd also note that the oil has changed over the years, the stuff I bought with the bike in 2003 went in looking dirty! Plus you had to shake it up as it partly separated.

My inclination is to make the oil changes more frequent rather than do double-flushing. The first three oil changes for my Mercury's Rohloff hub have average 75% of the recommended interval although there's an element of chance in that as I aim to do the changes when the weather is warm and the oil flows more freely. I wouldn't be wanting completely clean oil as having some fine metallic dust in the oil in the hub probably helps with the final polishing of the gear surfaces.
