Andrew Talansky, one of the most successful American GC riders over the past five years, announced his retirement from professional cycling Tuesday.

The 28-year-old Californian posted the news on his Instagram account. He said, “I’ve lived out a dream and I have Slipstream Sports and you, the fans, to thank for that.”

Talansky was fifth overall in last year’s Vuelta a España. He also won the 2014 Critérium du Dauphiné and was second overall in Paris-Nice the year prior. His best result in 2017 was a win in stage 5 of the Amgen Tour of California, a win that snapped his Cannondale-Drapac team’s winless drought in the WorldTour.

The future of his Cannondale-Drapac team is in jeopardy. Management company Slipstream sports announced that the team might fold at the end of 2017 due to a sponsorship shortfall. It is currently running a crowdfunding campaign in an attempt to raise $7 million.
