Verificando o Cubo Dianteiro da Bicicleta
O cubo dianteiro deve segurar a roda firmemente na bicicleta e também permitir que a roda gire.
Is the front hub loose enough
A Good Test
If you set the valve hole at three o’clock a good wheel bearing will allow the the weight of the valve, or the weight of joint in the rim which is opposite the valve to pull to the bottom. On a brand new or recently serviced bike the front hub may be full of grease, otherwise a bearing in condition will allow this movement.
