I'm not sure if you're meaning CO 145. Max grade on CO 145 is only 4.1%. As a comparison, the grade down into Silverthorne is 7% for 7 miles on I-70. The grade on CO 9 down into Breck is 8%. However, I think that although CO 9 is steeper, it is no more difficult than I-70. Coming down off the pass you'll need to stay in lower gears through those first few switchbacks off the top. You'll be going slow at the top anyway, so just stay slow.
Thank you for the information - sounds like a pretty steep grade.
