(CNN) The line-ups for the 2019 Global Champions League (GCL) have been announced -- with a number of high-profile stars making a switch to different teams.

London Knights, last year's winner of the GCL Championship, has retained the core of its powerful line up and added Max Kuhner to the ranks of Ben Maher, Olivier Philippaerts, Nicola Philippaerts, Martin Fuchs and U25 talent Emily Moffitt.

Similarly, Madrid in Motion -- winners of the first-ever GCL Super Cup at the GC Prague Playoffs last year -- has added Mark McAuley and Cindy van der Straten to what will be a strong outfit.

Each of the 16 squads will now field a roster of six riders -- one more rider than last season -- to allow for more flexibility.
