Tips, hell, too much to go into really, you have a lot to learn, but a few:
Dont let gaps appear in front you of more than a few meters, if you do you will either get dropped or a severe talking too.
Dont look behind you, eyes front all the time with the brakes covered.
Dont make sudden movements, if you do you will either take somebody down behind you or end up skating down the road on your arse as you take your own front wheel out.
Enjoy, thats assuming you can breathe through your arse !!
Edit: Its not the "darkside" its called a road bike
