came in here to post this. just dont do what I did and start too early in the winter. Were it not for my back-ordered stem, my bike would be done and I would only get to look at it for the next 3-4 months, not ride it. Perhaps the back-order is a blessing.

and if you are looking for fitness, cross train! You can lift, snowshoe/cross country ski, ride on a trainer or stationary bike... and hold out for those freakish 40 degree days to get the bike out for a short ride!
