Cipo can get over the mountains when he wants to, like in this year's giro. He wanted to finish with the purple jersey and sthe stage record. And he has done mountainous races like the Tour of Romandie, a couple of years ago, and I think he finished that. But no, he's not a mountaineer.
As for Zabel, he's not having the season he usually does, but I doubt it's age, since Cipo is older! Telekom is having a bit of a moral crisis this year and Zabel has been without his leadout man, Fagnini, for the last few races.
