A friend of mine brought round his son's new to him bike for me to give the once over. He said the wheels needed a bit of truing but otherwise was OK.
The bike is an Apollo Slant. I have no idea how old it is but it had a quill stem, adjustable bottom bracket and 3x7 drive train, so must be quite old.
However, it was in practically new condition, it must have been dry stored in a garage, there were cobwebs.
Anyway I set about checking it over.
The headset was loose, the hub bearings were tight, both derailleurs needed adjustment, the tyres needed some air.
I trued the wheels then set about adjusting the brakes (v brakes).
And there, I met a problem I have never seen before. Even with the brake blocks away from the rim there was a funny clicking noise when I span the front wheel.
It turned out to be tiny bits of rubber sticking out from the tyre very near the rim (the nibs you get on new tyres). They were hitting the brake blocks.
I had to pick them all off by hand to get a nice quietly spinning wheel.
