The top descending speeds have always been obtained on snow. Apart from that, the ashes of a volcano have been the other surface used. In November 2001, Eric Barone descended on the Cerro Negro volcano in Nicaragua at , beating his previous record achieved in Hawaii in 1999. Barone believed he could do more, and returned to the same location on 12 May 2002 when he reached on a serial production bicycle and , on a prototype bicycle, a world record. Markus Stöckl did beat the serial production bicycle record in 2011 when he reached on a volcano in Nicaragua and again in 2017 when he reached down a volcano in Chile. The prototype bicycle record, on a volcano, still belongs to Barone.
