Matt Cronshaw, Matt Holmes and teenagers Joe Evans and Tristan Robbins have also re-signed, but Liam Holohan will move to Team WIGGINS.
Speaking of the partnership with Cavendish, Roger Hammond said: “I’m so proud that Mark will join Madison Genesis on the next phase of the team’s journey.
“I have known Mark a long time, his knowledge and passion for the sport is second to none, combined with his enthusiasm to help nurture and support the up and coming generations, I could not have ever hoped for a better person to look to the future with the team.”
Four new signings will also bolster the team’s ranks for 2016, with Irishman Felix English joining from JLT-Condor.
Gruff Lewis (Pedal Heaven) has also joined, alongside 34-year-old Frenchman Alexandre Blain (Team Marseille 13 KTM), who re-joins the British domestic scene after previously riding for Endura and Raleigh.
The 2016 roster is completed by New Zealand riders Taylor Gunman (Avanti), who won this year’s New Zealand Cycle Classic and was also crowned Oceanian Continental road race champion.
Hammond, meanwhile, will also serve as a DS with Dimension Data in 2016, helping to support their Classics team.
He added on his new role: “I am very excited to be joining this fantastic project, with so many ex team mates or managers within the team it feels like I’m returning to my family.
“Cycling has been so influential in the path my life has taken and the rich experiences I have enjoyed along the way.
“To be part of this project that not only focusses on giving riders the chance to achieve their dreams competitively but – by supporting Qhubeka – also giving children the chance of an education through the medium of the bike was an opportunity not to be missed.”
