Lovely looking bike Paul.
Of course it would have looked better in Blue if only I had been quick enough! 😢

Looks about the perfect set up to me. Awesome bike!
Thanks, if I don't know what I like by now there's no hope... The previous one was pretty close, but I took advantage of the swap to tweak it a little.

How do you find the computer mount on the stem cap?  What is that handlebar bag?
The Garmin top cap - I'm not sure, I've had the same on another bike for a while, but that has longer top tube and shorter stem, on the Merc I catch it with my knee occasionally. I'm not sure whether I'll learn not to or give up first.  The nice thing about it is it's unobtrusive when the Garmin isn't fitted.  Not as nice as an out front mount if not using a bar bag, it's less in your field of view.
the bar bag is an Ortlieb Compact, bought secondhand a couple of years ago and I like it, though it looks like a handbag when not attached to the bike.

Hello everyone, thanks for the replies to this post. I took the plunge and ordered a set of Duremes for my Mk2 Sherpa.

I went for a short ride this morning at the local wind farm (gravel tracks of varying quality) and am really pleased with them.The ride is very comfortable, not much slower the Supremes, but a lot more secure on loose surfaces.

The first half of the ride the rear tyre was a bit squishy. I stopped to check the pressure and discovered it was only 36psi! Either I've lost some pressure since fitting on Saturday or my floor pump pressure gauge is broken. Once I increased the pressure to just under 45psi, the ride was even better.

I'm running them on DRC MT19 rims, which have an internal width of 17.5mm, and the tyres measure 44.3mm wide. They look fairly round so I'm guessing the height is about the same.

They are a neat fit under my Berthoud 50mm mudguards, but there is still reasonable clearance. I might change to 55mm SKS chromoplastic in due course to give more clearance.

The only thing I need to do now is reverse the front tyre because the direction of travel arrow (which I missed when fitting) is going backwards  :)

Remember my doubts about the switches on Busch + Müller battery rear lamps. When I last used these (about 15-20 years ago, maybe more) the simple slide switches B&M then used would fail after several months of all-weather use.

The Secula is a relatively recent model, so B&M may have addressed this issue. From the photo on their website it looks to be a different type of switch, hopefully more weatherproof.

Never had a problem with the Cateye switches, these are protected by a rubber cap. The switches on relatively recent B&M front lamps also seem to be OK, in at least 10 years of use I have never had a problem with the Ixon battery powered front lamp (rubber cap) or the Cyo dynamo lamps (large circular turn switch).

Thanks Martin, the photo is useful.  The battery version of the  Secula mudguard light has just gone to the top of the list.

Update on my Raven Sport Tour.

Since I retired in 2018 I have been hankering after fatter tyres, to make the bike more suitable for the occasional "short cut" on paths and tracks.

So I swapped out the Kojaks for 42 mm Supremes (true width about 37-38 mm). These are much more comfortable both on and off tarmac, and I haven't noticed any significant performance hit over the Kojaks when I ride exclusively on good roads.

As the Kojaks weren't all that worn I sold them on, they have gone to a new home on a recumbent bike.

The 50x19 gearing still suits me, and the 1st chain I fitted, a  KMC X1, did 1300 kms on the factory lube before I swapped it off for cleaning and relubing. Less distance between maintenance intervals than with a Chainglider, but still reasonably good, and much better than I used to get on my derailleur bikes.

Photo of the rear lamps on my RST.

The ugly but strong steel bracket on the mudguard for the Cateye TL-LD1100 lamp, certainly not neat enough for you.

And the Secula mudguard mounted lamp. Mine has ugly wiring, but this could be an option for you in the battery version. It uses AAA so is significantly lighter than the Cateye, important when fitted at the end of the mudguard.

An advantage of a lamp like the Secula mounted on the rear part of the mudguard is that it is never obscured by luggage, which can be an issue with a rack mounted lamp.

That says a lot about quality of Rohloffs and dynahubs.
It always pays to buy the best !

Meet the new Merc, much like the old Merc

new-merc by Paul, on Flickr

This Rohloff is now in it's forth frame, three of them Thorns, the front dynamo hub is now on it's sixth bike!
Other than that, I've made some minor changes and upped the tyre size and it's as it was.  I'll try not to ride this one into the back if a car, I have other bikes for that.
