Like olivier_g, I can confirm that it's perfectly fine on a road bike, although 6km of the climb and 2km of the descent to Laffrey would be better on a gravel bike. The road seems to have been tarmacked in the past, so it's fairly flat with some gravel on it (but not dangerous). The worst part is at the start of the descent, but it's not steep, so it's okay too. Nice views on the way down... read more

Comme olivier_g je confirme que ca passe toutà fait en vélo de route même si 6km de la montée et 2km de la descente vers Laffrey iraient mieux avec un gravel. La route semble avoir été goudronnée dans le passé, elle est donc assez plane avec des graviers dessus (mais pas dangereuse)
La partie la moins bonne est au début de la descente, mais ce n'est pas raide, donc ca passe aussi.

Particularly steep start (some sections approaching 20％) with little respite. The rest is more regular.
I recommend gravel for this climb, given that a significant section of the road is unpaved.
Once you reach the pass, you can continue on the track opposite (poor quality), which will take you back down to Laffrey for a loop, and which also offers a beautiful unobstructed view of the Taillefer and Belledonne massifs.

Début particulièrement raide (quelques sections avoisinants les 20％) et sans trop de répit. La suite est plus régulière.
Je recommande un gravel pour cette ascension, compte tenu qu'une section importante de la route est sans revêtement.
Arrivé au col, il est possible de continuer sur la piste en face (mauvaise qualité), ce qui permet de redescendre sur Laffrey pour faire une boucle, et ce qui offre de plus une belle vue dégagée sur les massifs du Taillefer et de Belledonne.
