Coverings rappeln u. Do not squeak. Do this thing right. Previously had 5.5 cm long racing pads, the new 7 cm long coverings have more space and slow down. Better. Red is something different, but gum seems to be softer. This also good braking performance. Whether the wear is greater to be seen. But for good braking action I do not care. The fumbling when setting equals dam at all surfaces .......! He has to live, what to invent a new one.
