I posted this on a forum awhile back and thought I would share it with you good folks.

Lift the rear wheel from ground by picking up the saddle of your bicycle and give the left pedal a hard and quick half-turn spin, then count the number of the turns you will have before a complete stop of the rear wheel; please let us know the number.

I got a 70' or 80's Precision PR6006 made-in-Canada mountain bike and the number I tested was 170. That's perhaps a main reason why I always like this over 30-year old bike. It is eager to go when you ride.

I tested a lot new bikes in the stores, both department stores and a couple of LBS's this way, they are all somewhere between 15 to 120 turns, even for brand names such as Trek, Giant, or Norco.

I trust that this could be the reason why other people here also like the old bikes but they may never notice this hidden difference which might be why old bikes do have the QUALITY.
