This morning it was 7F in Denver and I wore:
Flanned lined pants over bike shorts
Thin longsleeved baselayer
Warm-ish winter REI jacket (puffy-style)
LG Lobster gloves
I was TOASTY. A little too toasty.
I bike in København nearly every day. It rarely gets 10F, but it is 15F to 20F a lot of wind. I wear “longjohns” top and bottom with a windbreaker top and pants over my real, and loose, pants and top.. A balaclava type hat. I don’t wear a ski mask because they cut my vision too much. The lobster gloves are great! A nice trick is to use wrist bands to seal your sleeves.
Keep your hands, feet and head warm and you can be out for hours. If you get a bit cold shift to a different gear and pedal harder.
I just put my snow tires on the Batavus:-)
Make sure you have great lights front and back!!! Sunrise is later and sunset earlier. (here it is 8:30 am and 3:45 pm now)
here is a video some people made
Bike lanes are plowed first:-)
I usually go with
2 pairs of socks – 1 thin pair, one thicker
cycling sneakers (crank bros)
undies or bike shorts
thin performance shirt, long sleeves
cotton long sleeved t-shirt
sweatshirt or sweater
cycling windbreaker (endura gridlock for me)
and if i’m on a longer ride, I’ll probably end up stopping and taking off the sweater/sweatshirt layer after a couple of miles to keep from overheating.
Above 30F and I’ll skip a layer top and bottom
If it’s 10F and raining (oddly enough completely possible) I’ll catch a ride.
Personally I’d wear a heavy wool topcoat, long underwear, hat, coat, gloves, and scarf, and travel by automobile or mass transit. Cold weather is why they invented gyms!
I’m new to riding in the cold and haven’t had that low of a temp yet but I’m finding the layering thing means pile on layers — don’t have to be the perfect layers but layers. Put the good stuff on first (the technical fabrics that keep you dry) and then pile on stuff on top. Also found that I absolutely have to have earwarmers — can do without a hat but can’t STAND the ears being cold!
Here’s 19 deg: http://greaseragmpls.wordpress.com/2011/11/17/not-that-you-asked-but-this-is-what-im-wearing-today/
For 10 deg, just make sure you have something to cover your eyes, ears and face, and something windproof is nice. Warm shoes (vents= bad!) and windproof mittens are important. You could get by with heavier weight tights, booties and a wicking layer with a softshell.

Grease Rag Ride & Wrench
It depends on how hard you are planning on riding.
Here in Boston, I ride a road bike as much as the road conditions let me. Wind chill is as much of a concern as ambient temps for me.
At those temps, I wear a pair of wind-tights over a pair of winter bib-tights. A wind-proof base-layer, long-sleeve winter-weight jersey and an e-vent jacket. Wind-proof liners inside lobster-mits, double socks and booties are a must, as are a decent balaclava and glasses (to keep your eyes from watering up in the wind).
You’d also be surprised how much a little saran wrap (or sandwich baggie) over the toes of your socks and make a difference when riding in road shoes in the winter.
The most important thing is keeping the extremities (and ears) warm. For everything else, you can just pedal harder to keep warm.
I commute about 10 miles each way. I prefer to pedal hard and get to my destination as quickly as possible as opposed to pedaling easy and arriving fresh. It also helps that I have a gym in my building. YMMV.
