In a Twitter post, Deignan said: “With a combination of sadness but also a huge sense of pride and optimism I would like to announce my retirement from professional cycling.

“As a 15-year-old riding on the roads around Donegal I never dreamt that I would go on to make the sport I love my job for 14 years.”

Deignan turned pro in 2014 with AG2R, before joining the Cervelo Test Team in 2008.

He then rode for RadioShack for one year in 2011, followed by two years at UnitedHealthcare.
