The 35-year old leadout specialist and long-time wingman for Mark Cavendish has spent the past three years with the African registered outfit.
“I'm looking forward to racing my 16th season professionally with Dimension Data for Qhubeka in 2019. This will be my fourth season with the team where we have had some great success over the past three years,” Renshaw said.
“I'm excited to meet all my current teammates and all the new riders that will join us next season at our training camp in Cape Town next month.
“Working with our new sprinter Giacomo Nizzolo next season as well seeing Ryan Gibbons continue to develop will be very exciting, I looking forward to helping him and our other leaders in the sprint finals next season in my favourite position of lead-out rider. I will be sharing all my years of experience on the road to bring the team our best results.
To celebrate the announcement Renshaw pledged a special contribution to the team aligned Qhubeka charity which seeks to mobilise people through bicycles.
“The Qhubeka charity is a huge part of this team and I am very proud to be a part of this. Helping put kids on bikes is a big motivation for all riders and the chance to be part of a handover each year in South Africa means a lot to me," Renshaw said.
“This year I will purchase four Qhubeka bikes; one for each year I have been with Dimension Data that will help a child in Africa.
“Finally, a big thank you to Douglas Ryder for the opportunity to once again be part of the World Tour and to all the staff that work so hard during the season to help the riders.
“I can't wait for 2019 to roll around.”
