Cycle Sport is a great magazine, but it's pricey. It was a lot more fun when you could get the British version, which had lots of reviews and ads for stuff you couldn't buy here in the States.
I agree with Skydive69. Between Cyclingnews.com and Velonews.com, there's rarely much in each issue of Velonews that I haven't read already. Remember back in the day when you had to wait for the magazine to come out to find out details of a big race like the Tour?
