A climb with steep gradients and little downtime
1st climb in a series of steep climbs
The asphalt on the esterencuby side is really very good
The descent on the Saint Michel side is really rough, but as I didn't know the area, I had planned this descent so that I could continue directly with the climb that passes under the Behisaro cross and joins the Route Napoléon at the 707m mark to continue on to Arnosteguy.
Anecdote: at the end of the first climb, I went left without really checking where I was and continued on the track up to 930 m altitude (I have 30 mm road tyres and even if it feels good, it's not to be recommended): I was thus able to see that with light gravel tyres, you can continue without any problem through the mountain pastures to come out on the Route Napoléon at 1096 m altitude in sumptuous landscapes. Besides, for the descent to Saint Michel it's probably better to have tyres that are a bit bigger and sturdier than my Blackbird Hutchinson and Pirelli PZero, even in 30s.
As for the transmission, it depends on your ability to develop watts and still have some margin in this kind of percentage to be able to hold on and offer yourself some nice sequences and a full day's riding.
Personally I have a 10/36 with 49/33 and that allows me to do everything and above all with the priority of still being able to go over 15％ after more than 4000d+or 200bornes (favourite sector Barguilere, Ariège, Montagne Noire, Corbières Fenouillèdes Plantaurel).
I had a great day a few days ago when, at the end of the tour, I climbed to the Bilgoza pass via Esterencuby (climb not listed on this site) after 3500d+ and I found that this little pass had some spice 😅 the Mendive side is cooler but we have to get back to our gîte in Alcay 😅
In any case I fell in love with the Basque country, everything for a holiday 👌👌👌
The photo is on the 930 side point, normally you don't go past it 😅

Une montée avec des pourcentages soutenus et peu de temps mort
1ère montée d une empilement de montées raides
L asphalte côté esterencuby est vraiment très correcte
La descente côté saint Michel est vraiment dégradée mais ne connaissant pas le secteur j avait prévu cette descente pour enchaîner directement avec la montée qui passe sous la croix de Behisaro et rejoint la route Napoléon au point côté 707m pour poursuivre sur Arnosteguy
Anecdote a la fin de la première montée je suis parti à gauche sans vraiment contrôler ou je me situait et j ai poursuivi sur piste jusque ers 930 m d altitude (j ai des pneus route en 30 et même si cela fait ce n est pas à conseiller): j ai pu ainsi constater qu avec de pneu de type light gravel on peut sans problème poursuivre a travers les estives pour sortir sur la route Napoléon à la côte 1096m dans des paysages somptueux. D ailleurs pour la descente sur saint Michel c'est probablement mieux d avoir des pneus un peu plus gros et robuste que mes Blackbird Hutchinson et Pirelli PZero même en 30
Pour la transmission c est selon vôtre capacité à développer des Watt tout en ayant de la marge dans ce genre de pourcentage pour pouvoir tenir et s'offrir de beaux enchaînement et une journée bien remplie
Personnellement j ai une 10/36 avec 49/33 et cela me permet de tout faire et surtout avec comme priorité de pouvoir encore passer du plus de 15％ après plus de 4000d+ou 200bornes (secteur de prédilection Barguilere, Ariège, Montagne Noire, Corbières Fenouillèdes Plantaurel)
J ai fait une belle journée il y a quelques jours ou en fin de tour je suis monté au col de Bilgoza par Esterencuby (montée non répertoriée sur ce site) après 3500d+ et j ai trouvé que ce petit col avait du piquant 😅 le côté Mendive est plus cool mais il faut rentrer à notre gîte à Alcay 😅
En tout cas je suis tombé amoureux du Pays Basque, tout pour passer des vacances 👌👌👌
La photo est au point côté 930 normalement on n y passe pas 😅
