If you've already done some mileage, this climb is pretty tough. Not long, but a decent gradient. The climb has a good road surface and in terms of traffic it is perfect. Wonderfully quiet.

Als je al wat kilometers hebt gemaakt, is deze klim behoorlijk pittig. Niet lang, maar een behoorlijk stijgingspercentage. De klim heeft een goed wegdek en qua verkeer is het perfect. Heerlijk rustig.

The name says it all... It breaks your legs and the km with the hardest gradients calm you down right away! Besides, it's pretty stylish to be able to say that you climbed the Underworld!

Le nom dit tout...Ca casse bien les jambes et les km avec les pourcentages les plus durs te calment tout de suite ! En plus, c'est assez stylé de pouvoir dire que t'as gravis les Enfers !

This means a small front chainring of 34 teeth, combined with a rear cassette where, depending on your level, strength, and experience, you choose a sprocket with 30, 32, or even 34 teeth. Remember that a smooth cadence is always more efficient!
