Wheel Alignment
After fitting 5 gears on by old bike it felt as if the bike was pulling to one side. On viewing the bike held in a straight ahead position from rear, it looks like the rear wheel does not follow the front wheel, ie they lie on two different longitudinal planes. Is this because the distance of the hub from the frame at the side of the gears is different from the side without the gears? In that case, do I have to insert some spacers on the opposite side of the geared side of the rear axle? OR is there any other method commonly followed for fitting gears on a non geared bike?
