This route is phenomenal, you can ride at a pace to suit yourself, no nasty surprises so long as you read the road ahead and be ready for the unforseeable. There is an excellent shop / restaurant at the top where the cyclists load up with carbohydrates.
Links well to the Stelvio pass if you take a right at Santa Maria.
Well worht going out of your way to do this one.
