For a few months I have been watching my progress up Everest showing the red line finally reaching 99%. After my next ride that should have taken me over 100%, my red line was at the summit but my progress showed 17%! What has happened? How can I unlock a tron?
Also the challenge screen shows the Everest height as 29 thousand feet and shows my total height achieved as 164 thousand feet. Weird.
Sounds like you are almost there. Once you complete the height of Everest, you should have unlocked the Emonda frame. Then the ride for the Concept Z1 bike continues to 164042 feet (50000 meters)
