Tyre

And not just any old tyre! It's brand new and I even got it fitted in the shop, even though they didn't really have the time but squeezed me in just before closing time. I had a feeling they wanted to support me because I needed the bike to get to work tomorrow. The car is always an option but I'd rather take the bike.
So that really made my day after finding a surprise puncture followed by the discovery of needing a new tyre too!
