Congrats for making it up (and down) the mountain safely under those conditions.
Thanks for saying that. It wasn't recklessly dangerous because we never allowed ourselves to accelerate to a dangerous speed. I did crash once, and it was the equivalent of tipping over. There wasn't a chance of flying off the mountain in an uncontrolled skid.

Still, the cold was super interesting to contend with!

When I climb mountains on my own, I tent to really pound through them.

I figure I have the holy grail of 1 x 10 traits, by chance or by self-fulfilling prophecy:

1) I travel light. When I overnight with Kelley, I have about 18lbs of gear and when I tour alone in the summer I have less than 10lbs.

2) I'm strong. Still young, with good strong legs and no knee problems whatsoever. I figure I have the muscle to protect my joints if climbing is arduous once in a while.

3) A 38 front with a 36 rear (which I'm waiting on order from the LBS) should be pretty close to my old setup of 34 front and 32 rear. So, I'm not actually making a huge sacrifice at the bottom. And 38 x 11 is still a good enough ratio to keep up on a group ride, assuming I brought my road tires...

I will look into the cross chaining and derailleur issue. I'm actually learning how to build bikes, and I did the conversion myself (under supervision of my mechanic). Since all the cabling and derailleur adjustment was done by me, it might need an extra set of eyes.
If you've taken a double and are simply using either the inner or outer ring positions without adjusting the bottom bracket you might be having some chain line issues and feel some vibration at one end of the cassette. When I took a triple and used the middle and inner positions as a super-compact double with 42/26 rings I adjusted to bottom bracket a bit so the gap between the 42 and 26 inch rings was centered on the cassette to minimize chain angle. You should adjust your bottom bracket (if you can) to center whatever ring you are using with the cassette or get a single crank and bottom bracket combo that gets the chain line right.
