Boss Dave Challinor said Rydel needs to use his anterior cruciate ligament injury as “motivation for a new challenge in League One” and that next season will be a “big one for him”.
“He needs to mature and establish himself into a consistent, reliable League One player, which we all feel he has shown that he can do if he focusses on what he needs to do day-to-day to improve and progress,” Challinor said.
“The contract extension gives him the time to do that now it has been agreed and signed, and we are all looking forward to continuing to work with him.”
Teenage midfielder Cody Johnson has also agreed new terms with the club.
The 19-year-old has made 12 appearances for Stockport – including four in League Two this season – and has signed a one-year deal.
