Second, the dilemma: I have two bicycles that I could take on my trip

1. Cervelo--Very light, stiff bike with standard double cranks (53/39, 11-26)
2. Cannondale Synapse--Bike that weighs about 3 lbs more than the one previously mentioned, but with compact double (50/34, 11-28)

Thank you for any input and opinions!
Personally, I cannot imagine using a standard double cranks going up mountains. You must be athletic!!!
