Action in Quebec will take place at the Mont-Sainte-Anne Bike Park, a regular fixture on the UCI World Cup circuit.

Champions will again be crowned in downhill and cross-country, alongside e-mountain bike which will debut at World Championship level.

In the men's elite downhill, three-time champion Loïc Bruni is defending the title he won in Lenzerheide in Switzerland last year.

He has faced tough battles with compatriot Loris Vergier on the World Cup circuit, while Australia's Troy Brosnan and Britain's Laurie Greenland will also hope to challenge.

In the women's downhill, Britain's defending champion Rachel Atherton is unable to bid for a sixth title due to injury.

Her compatriot Tahnée Seagrave, last year's silver medallist, will compete, despite not fully recovering from her own injury problems.

This presents Australia's Tracey Hannah with a good opportunity to strike.

Canada's 2017 world champion Miranda Miller is likely to be a force on home soil.

In the men's elite cross-country, seven-time champion Nino Schurter is aiming for a fifth consecutive gold, which would be a record.

Belgium's 2018 bronze medallist Mathieu van der Poel is out, so Schurter's main rival could be Swiss team-mate Mathias Flückiger.

Reigning women's cross-country champion Kate Courtney will hope to keep her title for the United States, but 2017 champion Jolanda Neff of Switzerland is also bidding to reach the top of the podium again.

Pauline Ferrand-Prévot of France enters the Championships in good form and will be a threat.

E-mountain bike has attracted riders from various fields for its debut, including cross-country Olympic champions Julien Absalon of France and Christoph Sauser of Switzerland.

They are joined by the likes of American former moto-cross rider Charlie Mullins and multiple age-group downhill world champion Jean-Pierre Bruni of France, the father of Loïc.

The women's e-mountain bike field includes Canada's cyclo-cross specialist Maghalie Rochette and four-cross rider Anneke Beerten of The Netherlands.

Both e-mountain bike events are on day one tomorrow, alongside the cross-country relay.

Junior cross-country takes centre stage on Thursday (August 29), before under-23 men's cross-country and qualification in the elite and junior downhill on Friday (August 30).

Saturday (August 31) features the elite and women's under-23 cross-country finals, ahead of the elite and junior downhill finals which close the event on Sunday (September 1).
