‘Cross and 3 punctures.

15°C, light S wind, dry but for rain in the last mile.

Building cloud.

A ride ruined. I stopped after 2 miles with a soft tyre to blow it back up. 2 miles later, it had lost pressure as I got onto the gravel section. The inner tubes are slime filled which seals punctures but I was thought the valve was bunged up. It certainly looked green (the colour of the slime).

Eventually, I took the tube out and found 2 needle-like thorns. Okay, 1 more try… No better. Being 10 miles from home, I put a normal tube in. Meanwhile the clouds loomed dark.

I’m now taking a break at home because I’m having troubles finding the holes to patch.

Try cyclocross they said…

Endless deep mud. It makes the going quite slow. The worst stretches returned an average 8 mph. It was tremendous fun though. That was the first outing on the ‘cross. Some stretches were such a quagmire that I had to jump off and run. There was lots of side slipping and the ever present threat of a cold water dunking in the canal.

Need to clean this better.

Slime tubes work in an interesting way. I pulled the cross bike out to find flat rear tyre. Slime tubes will self seal if you put some pressure in. Even better, if you can find the leak, you can see green blood bubbling out. The trick is to turn the wheel so that the leak is at the bottom. That way, the slime inside the tube will seep towards the puncture.
As I have been ill recently, the bike has stood still for a few weeks. This is a problem because if you spin a wheel, it feels very unbalanced. The slime has probably gathered at the bottom and added weight there.

By the way, I’m fully recovered.
