Some people were asking about the clamp on rear brake for track bikes that is available in Japan. I checked on it. They have two types, a regular and a *deluxe* model. The regular is a DiaCompe caliper and the deluxe is a Shimano. I believe that the lever is a nondescript type that comes with both models. Then there is the cable and clamping plates that comes along with them. The regular type is about $22, and the deluxe is $52.
