Montalvo, 30, held off Wizard in the final to take the WDSF World Breaking Championship title last year and became the first American to qualify for breaking at the Olympics.
Wizard, 27, won the WDSF championship in 2022.
New canoe slalom event, kayak cross
Having made its Olympic debut at Munich 1972, canoe slalom will see a new event added to its roster with kayak cross making its debut at Paris 2024.
Kayak cross is an extreme canoe slalom, which sees competitors in kayaks race on white water, jostling each other with their paddles for pole position.
The Olympic event will begin with timed solo runs before introducing a frenetic element of head-to-head competition as four racers face off against each other, vying for position on the course with placings changing rapidly and contact almost inevitable.
Britain’s world champion Joe Clarke and Australia’s Jessica Fox are among the favourites to win inaugural gold medals in the event, but the chaotic nature of the four-person races makes them almost impossible to predict.
There will be six medals up for grabs, and an equal number of men and women competing.
Kiteboarding to make Olympic debut
Kiteboarding, also known as kitesurfing, is a high-octane sport that will be among the 10 sailing events at Paris 2024 for the first time in Olympic history.
Kiteboarding will be held in Formula Kite format with 20 men and 20 women using approved kites in a wind range between five to 40 knots.
There will be three new mixed events in sailing, including mixed kiteboarding and mixed 470.
Other changes
Modern pentathlon was previously completed over the course of one day, but the Paris 2024 semi-final and final will be condensed into 90 minutes. The order of the disciplines will also be new, with short rest intervals.
A repechage round will be introduced to all individual track events in athletics from 200m to 1500m in distance. Replacing the individual 50km, the mixed team walking race will also make its Olympic debut at Paris 2024.
In artistic swimming, men will be eligible to compete for the first time in Olympic history. Acrobatic team routine has also been added to the programme.
A new women’s weight class, bantamweight, will be introduced in boxing while the men’s light heavyweight division will be removed.
Skeet mixed team event in shooting will replace the trap mixed team event.
In volleyball, teams will be split into three pools of four each, playing three matches in the pool phase.
Two extreme canoe slalom events have been added, while two canoe sprint events have been cut.

Climbing will have two events for male and female competitors in Paris – speed climbing and a combined bouldering and lead competition.
