if you were doing a tour from Turkey back to the UK via the Danube and the Rhine, what would be in your tool/spares kit?
I did -- twice and then some -- on my 2014 European double-crossing. After 10 days working in Bodrum Turkey, I largely followed the Danube E-W from the Black Sea at Constanta to coastal France and then again W-E (including the Danube source at Donaueschingen) and also did much of the Rhine and Rhine-Main canal connector as well as the Mosel for the major rivers and 'round the Bodensee (Lake Constance) and
over the Black Forest to the Tittesee. About 9,000kms in all over four months.
The EV6 -- if you choose to follow it in part or in whole - is actually several routes. Often there are three options available, a quieter/longer one, a busier/shorter one and another more MTB oriented that may not be paved.
In Western Europe you'll often find bike shops near the route and can get what you want or need. Austria was the best in this regard, with roadside vending machines for Continental tires and tubes plus various other sundries and occasional public repair stations equipped with bike repair tools on tethers. As you go east, this was rarely the case in my experience. Along my routes in Croatia, Serbia, Romania and Bulgaria it was very difficult to find bike shops along the route and when I did, they were poorly stocked. For example, I felt lucky to find a single pair of v-brake pads in Corabia and most of the shops had only MTB knobbies in 26in or 700x23C racing tires with little in-between. Of course, places like Sofia, Budapest, Bratislava, Prague, and Begrade had everything you could wish for as those are major centers for commerce.

When all was said and done, I used very little in terms of tools and supplies:
I suffered only a single puncture in the entire journey, caused by a roofing staple in Giurgiu, Romania. My Crank Bros Power Pump worked well throughout and I checked tire pressure about every third day and topped off a couple strokes' worth every week.
I lubed my chain regularly, sometimes daily if it was raining. I used a mascara brush to floss it before relubing when it got dusty in western Romania.
I had a shop change the hub oil in Germany and kept my oil change kit as a spare if needed.
I adjusted the eccentric bottom bracket once in Romania on the return leg of my tour headed back to the Black Sea. This was the one time I had a problem. I removed a link-pair from the chain to compensate for the dialed-back eccentric and discovered the 8-sp quick-link I had was 0.1mm too thick to fit the chain(there are two thicknesses of 8-sp quick-links and I had the one that was to thick to fit my chain). I was really in a pickle but a kindly farmer came to my aid. I figured the best approach would be to file down the links to fit but he insisted on using a hammer and drift punch as my heart sank. He did manage to get it together after two hours'(!) work and I was surely grateful. It held together fine for the rest of my trip, quickly wearing in the necessary amount for clearance. I've attached a photo of this hero below. What a nice and generous fellow he was! I repaid his kindness with a half-dozen premium chocolate bars I purchased from a magazine in the next village. People like him can really make or save an entire tour.
As for skills, I would suggest a general familiarity with basic bike repair but most especially:
Wheel removal and puncture repair/tube replacement and some familiarity with reconnecting your Rohloff cables (either bayonet or EX click-box).
Brake pad replacement/cable replacement and adjustment
Chain shortening and replacement along with adjusting and securing the eccentric bottom bracket (check in advance to be sure your quick links actually fit)
Basic wheel truing -- Roads in Bulgaria can be BAD with lots of frost heaves, broken pavement, occasional missing street hatch covers and what I called "tar blowups" caused by heavily filled potholes that see car and truck traffic before they have cooled. This squashes the fresh tar into big heaves that really unsettle the bike and rider.
Rohloff cable replacement -- at least familiarity with what's required even if you don't try it in advance.
Rohloff oil change procedure
In closing, I would add the suggestion that if you go one-way, you make it west-to-east. The prevailing winds will be with you and the hill slopes are gentler. It is much more work to go east-to-west. I was able to easily ride some 200km days eastbound fully loaded in hill country, yet struggled sometimes to make 112km/day westbound.
Hope this helps.
Best,
Dan.
