Greg Minnaar (born November 13, 1981 in Pietermaritzburg) is a South African World Champion mountain bike racer competing in downhill cycling. Greg first started to get noticed as a world class downhill racer at the age of 17, in 1999, racing select World Cups (including one in his home country of South Africa, in Stellenbosch) on a local shop team, aboard a Kona Stab Dee-Lux bike with a Marzocchi Monster T. fork. The following year, still a junior, he was picked up by British international team Animal Orange, which used Orange frames (222 for downhill and Ms. Isle for dual slalom) and RockShox suspension. That year (2000) Greg podiumed at a World Cup points series race for the first time. The following two years Greg rode for the mighty Global Racing team, aboard similar bikes to the previous years', and on this team, at the age of 19, he won the overall World Cup points series in the Elite downhill. In 2003 Greg switched to the Haro Lee Dungarees team, which used Intense designed and built DHR frames for the dowhill and their own short travel Werx trailbike frames for Four Cross, with Manitou suspension. It was aboard this team that, at the age of 21, Greg became World Champion of downhill. Following this, Greg was offered a spot on the infamous Team G Cross Honda, which used one-off internally geared framesmade by Honda, and Showa suspension. He accepted, and stayed on that team for four years, which included his second World Cup points series overall victory in 2005. After the sudden pulling out of the sport by Honda after the 2007 season, which ended on a bittersweet note with a dislocated and fractured shoulder early in his winning World Championship final run (Greg got back on the bike to salvage a painful 4th place finish), Greg was forced to switch teams yet again. He recently chose the Santa Cruz Syndicate team, alongside riders Steve Peat, Nathan Rennie, and Josh Bryceland for the 2008 season. He competes in the NORBA and Mountain Bike World Cup points series races, in the Elite Downhill and Four Cross events.

Aaron Holmes Gwin is an American professional downhill mountain biker from Morongo Valley, California. He is recently known for breaking on to the international World Cup scene after about 8 months of riding downhill. Many see Gwin as the savior for US downhilling on the international scene since his 10th place finish at the Mont Sainte-Anne World Cup in 2008 was the first American top 10 finish since 2004.

Aaron Gwin started his cycling career off early racing BMX from age 4. By age 8 Gwin was racing all the nationals. At age 12 Gwin moved on to motocross and raced up until he was 17 when he quit due to constant injuries. In 2008 at age 20 Gwin was loaned a bike by fellow professional downhill racer and good friend Cody Warren and was encouraged to compete in a race. In his first race in the Fontana Winter Series he got 3rd and began racing from then on, quickly signing with Yeti Cycles. He has since won two United States National Championships for Downhill, in 2009 and in 2010. Both were held in SolVista, Colorado
