6 miles and 2,500’ of. Ice and snowpack.
I bought your studded 4x26 big knobby, tires for my Biktrix Ultra FS. I can climb up there to 9,000’ from my home on Cheyenne mountain in this old Stage Coach road that is plowed by icy. I never have fallen. The really grab to ice so as you keep the wheels turning and don’t slow down too fast. I make it in 52 minutes on the uphill and sometimes slower in the downhill! I tried normal unstudded knobbies first, and it was all fright time. I’m 75 and a cancer warrior.
