I've got a borrowed road bike (GT series 2) which I'm going to use for a sprint Triathlon in 6 weeks time. The tyres on it look like they've got a hefty tread pattern once you get off the centre line.
Should I be looking for something completely slick to replace these with? I think I want reasonable puncture resistance as well. I don't want to loose out to my friends who I'm racing against due to a flat.
Anything else I need to think about?
