Been experiencing a speed wobble whenever i get up to speeds of 40-50 while descending. Obviously it is very scary when this happens. What is the correct way to prevent this? Could it be the bike? When it does occur what is the safest way to come out of it? I usually tap the brakes lightly to reduce my speed. Obviously if you go hard on the brakes you are going to go down hard.

Any tips would be useful.
