Returning from my first ever 100km ride on the "new" road bike and bang! Puncture on Rundle St opposite The Stag as I'm heading out of the city. No drama, I've got a repair kit and plonk myself down on the footpath to fix it. Can't find anything sticking in the tyre surface when I take a look at the side walls... No idea what I hit and I'm glad that tyre got me home! Guess I'll need to get a new rear rim.
