A Bolivian-owned biking outfit on Sagárnaga, one floor up in the Galería Doryan on the corner of Murillo, in the middle of the block where every second shopfront sells the same descent. They do one thing: the Death Road, with their own bikes and equipment, and they publish a gallery and a kit list rather than a price.
Open 10:00 to 18:00. They answer the mobile on WhatsApp; the landline is a landline.
