While it can be done on a 28, the ascent definitely calls for a 32/40T cassette (seated) Found the rear wheel spinning sand (out the saddle) Blazing sun, convenient rest stops, gorgeous views. With a
maximum grade of 21-24% Sunshine Canyon definitely requires pacing. Underestimated the climb for sure. It's convenient to blame altitude acclimation, wonky sleep, slacking nutrition/glucose exhaustion, 28T cassette, or emotional stress. In reality, the climb is just a bit soul-crushing. I recommend going up in peak condition...otherwise, relax. The descent offers short and steep switchbacks, many blind turns, very few potholes.
Epic ride.
