Chris Horner, who last September became the oldest winner of any of cycling’s three Grand Tours when he won the Vuelta at the age of 41, has signed for Lampre-Merida.

The American, now aged 42, had been struggling to find a team for 2014 with outfits such as Trek Factory Racing, which took over the licence from his former employers, RadioShack-Leopard, said to have been deterred by his reported €1 million salary demands.

Lampre-Merida, which previously recruited world champion Rui Costa from Movistar, announced Horner’s arrival on Twitter this morning.

The deal was brokered by his former team-mate, the retired sprinter Baden Cooke, whom Horner appointed as his agent earlier this month, replacing Michael Rutherford.

Horner saw off the challenge of Giro d’Italia champion Vincenzo Nibali to win last year’s Vuelta, but was dogged by accusations of doping, not helped when a mix-up over an address led to him missing an anti-doping control the day after the race finished.

Previously, he rode alongside Lance Armstrong at Astana and RadioShack, teams both managed by Johan Bruyneel, although he says he never saw any evidence of doping there, despite the United States Anti-Doping Agency (USADA) stating that it did take place.

Last November, he also denied that he was one of the riders linked to doping whose names were redacted in USADA’s Reasoned Decision into banning Armstrong for life and stripping him of the seven Tour de France titles he won between 1998 and 2005.

Horner is expected to begin his 2014 campaign at next week’s Trofeo Mallorca.
