Steepest kilometer starts at km 6.8 (20.1%!!!!)
PJAMM will ride and document this climb in June, 2018. We have confirmed with several Strava members who have ridden this climb that it can be done on a road bike:
Emiliano De Angeli Yes: all the way with a road bike
fDomenico Ferlauto - Certainly. I did it with bdc!
Hi John! The road up to Alpe Aleccio is paved, so it can be done on a road bike. Beware: km #8 is steep! See gradients here: http://www.salite.ch/8879.asp?Mappa=
matteo montani - is a very hard and narrow climb, but is asphalted and practicable. Pay close attention downhill :)
