This is my first post in this thread today. Have looked a few times.
My last 4 days have been sunny and about 4C(40F) on way to work and about -4C(24F) on way home. First couple of days felt quite cold but have got the hang of it now. Also did a couple of training rides in the day, seem to ride better in the cooler weather.
Keep up the commute and pass on the word. I've almost converted 2 people at work to commute.
