Redmond bikers: Can you ride all year long?
...just speaking up for the Local Bike Shop - if you are moving to Redmond permanently then it may make sense to have a bike with a warranty and the support of the LBS for when/if it goes wrong.

Also consider the mudguards situation - I know they are unfashionable but they are handy for the commute. Since Specialized bikes are designed for sunny California where nobody could ever imagine needing mudguards, you may want to also post a question on what people recommend.

You will only be cold if you get clothing that is not up to the job. You know the drill - baselayers, as many layers as you need on top and a breathable jacket. Overshoes and neoprene gloves optional...
