Alex Marin - The road to the podium Red Bull Cerro Abajo

Red Bull Cerro Abajo isn't downhill racing as most people know it. Riders drop straight through cities, flights of concrete stairs, tight alley corners, walls of spectators inches from the tape, at speeds that leave no room for a bad line. It's the fastest-growing discipline in gravity riding, and Genova's course is one of the hardest on the calendar: 2.2 km through the historic city centre, with 279 metres of vertical drop.
Alex Marín has spent the last months making this discipline his.

Back in February, Alex closed out Valparaíso with a top-10 finish, a strong result on one of the series' most iconic tracks, and the moment his focus shifted fully onto urban DH. From there, everything led to Genova.

A week before Genova, that trust was already on record, filmed, posted, public. What was left was proving it on the stairs.

Three weeks out, Alex and Tannus confirmed another year together. Then, days before the race, he posted the video above: what it actually takes to hit stairs at 70 km/h without wrecking a rim.

Installing the setup

Concrete stairs, blind corners, full speed. No margin for equipment that can't take the hit. Alex crossed the line in third place, earning his first podium in the discipline and one of the biggest results of his career. Throughout the race, Tannus Tubeless PRO handled the repeated impacts of Genova's concrete stair sets, allowing Alex to stay focused on the fastest line all the way to the finish.
