I've just started cycling to work- it's about 10 miles each way and part of the route is quite busy so it takes me about an hour. When I cycled to my old job it was only 15 minutes away and I never bothered with anything cycling-specific so I'd assumed I'd be all Dutch and just hop off my bike and rock up to my desk with a slight healthy glow - pah!
What's the best clothing for a longish commute? I've already discovered that tights are bad news .. Hence the chafing question 
Any other tips gratefully received
