Jonathan Castroviejo won the prologue at Romandie and at Madrid and is a young, promising rider who is good at ITTs - 8th in Tirreno-adriatico and 9th in the longer Romandie ITT.
José Iván Gutiérrez... you really want me to explain? Multiple national ITT champion, twice Eneco Tour winner, has won and podiumed ITTs at the top level for best part of a decade now including 2nd in the Worlds in 2005, and is one of the most respected domestiques out there.
Jesús Herrada is a very, very promising youngster with a good ITT. He's a neo-pro this year who has been turning some heads.
Alejandro Marque rides mostly in Portugal and has been a good ITT rider and rouleur for David Blanco at Palmeiras for a couple of years. He's always been an ITT specialist.
Gorka Izagirre is another promising Euskaltel youngster with cyclocross experience.
Truth be told, it's not the strongest lineup, for sure, but there are some other decent names further down - David Blanco and David Bernabéu both appear way down but both are out of form, time and aging. Rubén Plaza is a good time triallist who is out injured, Héctor Guerra is banned, the other GC men with good time trials (Sánchez, for example) aren't riding.
But overall, the depth of ITT riding in Spain is pretty weak. Juan José Cobo was roped into representing them in the Worlds ITT in 2009 after the suspension of Guerra.
