Tough question. My Foes FXR (old style) clearly desends better than my Niota, but the Niota climbs SO MUCH better. The Foes is more stable, but the Niota is much quicker and in 80% of situations, much, much faster. I think you have to look at where/how you ride and find the bike that fits you & your style the best...for me it is the Niota.
