Good suggestion Charles. Forgot to mention that depending on bike and seatstay size and collector/paint sensitivity a lot of guys used a clamp on brake for control on the back. Ted Ernst Palos Verdes Estates, CA
To avoid hassle of drilling and mounting brakes in front or rear of a collectable track frame without holes already there I suggest the use of modern disc brakes and correct hubs (way past time line). This avoids the potential fork crown or rear brake bridge failure and frame is left untouched in original state. Charles Nighbor Walnut Creek, CA PS I seen fixed bikes up on all 4000 feet of it Mt. Diablo and have followed them down. All have had brakes. All made it down at about 20MPH
