I can not recommend Route No.9 in my opinion.
Actually only 2m wide gravel passages, the gravel is missing under the wheels, then it is asphalt. On the Czech side of the route, one drives only on the asphalt.
The only stretch section that was a bit more difficult is the 200m piece to Klingenthal to the Schwarzberg high. The singletrail pictures do not show the official track, so I deviated from the track. Since parallel ran a trail and once the route was blocked (asphalting measures).
A 30 tire on the road bike and you can race around with it.
