I like that for once the northern country half hasn't been forgotten but looking at the inclines here and for example PC7 between Lëpschter-Dellt and Fléiber (try it and feel it😅), I think Provelo should also advocate for different sign symbology on more extreme cycling terrain. The occasional cyclist or tourist who doesn't know the topography in detail, risks becoming super demotivated and will struggle reaching his destination. Without an ebike or sub 1.1 gear ratio it's quite a challenge for most amateur riders.
