Update -
As Daniel pointed out in the comments below, this is an unusual type of roller cam brake that is fixed to the fork using a single bolt through the fork rather than cantilever fixings
I have found two examples of roller cam brakes that uses a single bolt - Odyssey Bulldog and Dia Compe Big Dog - but both seem to have been discontinued for a long time
I will leave this question as unanswered a little longer in case anyone know of other brands that make these brakes that are currently available
I have a long reach brake that I've put on a refurbished old Chinese bike, it looks fantastic and it's a perfect fit for the old fork and new 700c wheel combo that needs about 95 mm reach
I am looking to refurbish another old bike, but I can't seem to find this type of brake anywhere. The one that I have came from the Taiwanese stockist Ducas (www.ducas-bike.com), but they no longer have it in stock and they have not been able to help me find one somewhere else
Any help identifying this type of brake or a good long reach alternative (I need at least 95 mm) would be much appreciated
