I love these Gallium Pro frames. I'm on my 3rd version, they just get better and better. the latest 2020 version retains the amazing lightness for climbing, but gets even more comfy for long days out, and best of all is so stiff up front for directional control and feedback on high speed descents. throw it into switchbacks and alpine descents and it comes alive. late braking into corners at speed is reassuringly stable. the perfect bike for enjoying the ups and downs of days in the mountains.
