If you take a closer look at the results lists from all events held at the Nordschleife in recent years, you will notice that the winners very often rode on Michelin tyres. Recently, Michelin has brought the famous "CUP" tyres to the road bike sector. Logically, what works on a Porsche GT3 should also be a very fast option for a road bike.
"Light or bright." With new generations of lighting systems, you no longer have to decide. Even compact new models like the Sigma Buster 800 give you a floodlit field in the Eifel. In terms of longer performance, models with an external battery with a larger capacity that can also be quickly replaced are recommended, especially for single competitors.
You don't really need a sat nav, but an on-board computer to monitor important metrics is indispensable in such a long race. The Garmin Edge 1040 will easily go for 24 hours without needing to “refuel”/recharge. The Hammerhead, on the other hand, can tell you exactly how long the climb will take and how steep the Hohe Acht really is, all thanks to the Climb Pro feature. Over 24 hours, however, the Karoo will be connected to the power bank from time to time.
