Pressurized air to be precise. Ever since my little spill I have been very wary on my bike. The last 2 days the back wheel felt erratic and I just couldn't trust it.
I checked the tyre pressure and it was way too low. So after wrestling with a pump in a garage (why do they have to be so awkward) I sorted the air pressure out.
The bike feels a lot more manageable and I have much more confidence in it. All I need to do is sort the lack of acceleration and I will be sorted but i think that's a problem for after Christmas
