They're going fast ***because*** they're all riding together.

Pacelines are truly an animal of their own, wiht their own physics *and* psychology. It is most certainly more than a question of being able to go fast. I'd highly, highly recommend finding somebody to help you learn drafting skills (though perhaps you're braver than I ;-)). It really helped me to be able to practice with one or two people and ask questions. Most of those 'young guy' pacelines are going too fast to allow for questions, and mistakes can land people in hospital.

Get the tires - you'll ***love it***
