A few questions for you Boffs...
1. If you squeeze a tube hard enough, you will find Silvery powder coming out of the valve...
What is this, and why is it in the tube in the first place?
2. My rims 'pit' very badly. (They lose shards of Metal all the time, which end up in my blocks.)...
Why?
Thanks...
