Brake pads against the tires?
Saw a bike today, chained up to a sign pole in Camden, NJ, USA. Wish I had brought my camera with me. The owner had reconditioned an old mountain bike. Frame was rattle-can painted so I didn't know what brand bike it was. Everything was clean and shiny. Just one thing seemed wrong - both front and rear brakes were adjusted so the pads would clamp down on the tire 1/4" to 1/2" above the rim. These were knobby tires and it looked like the top part of the pad would border on the edge of the lowest row of knobs. The pads were adjusted close to the tire and it looked like it would take little brake handle pressure to make contact - like with most brakepads over rims.
Has anyone seen this before?
