The Gravity Group, LLC is a roller coaster design firm based in Cincinnati, Ohio, USA. The group specialises in wooden roller coasters. It is made up of a core group of five people, who all have backgrounds in civil, structural and mechanical engineering.
Gravity Group was founded in July 2002 by employees of the famed, but now defunct Custom Coasters International. Because of this, it's employees have had experience with over 40 roller coasters. The first roller coaster designed under the Gravity Group name is Hades (now Hades 360) at Mt. Olympus Water & Theme Park, which opened in 2005.
The company also designed Ravine Flyer II at Waldameer in Erie, Pennsylvania, USA. It opened in 2008, and is currently ranked at #6. Another notable roller coaster designed by the firm is Wooden Warrior at Quassy Amusement Park, which gives a great ride, despite being only 35 feet tall.
In 2008, members of The Gravity Group announced the development of their own wooden roller coaster trains, called Timberliners. They are manufactured by Gravitykraft Corporation,, a sister company of Gravity Group. The Gravity Group promotes their trains as the only wooden coaster trains capable of steering through curves, resulting in a more comfortable and maintenance friendly ride. Timberliners were planned to debut on Voyage at Holiday World for the 2010 season, but the trains faced delays. In 2011, Timberliners were installed on Wooden Warrior at Quassy Amusement Park and Twister at Gröna Lund in Sweden.
The Gravity Group have designed a total of 15 roller coasters, all of which are wooden. As well as those included in the table below, there are three new Gravity Group roller coasters being installed in various Fantawild Adventure locations.
