Remeber these those ALTENBURGER dual pivot brakes that never took off, then Shimano came to rule the world (off topic). check them out on this 70s Bottechia
In respect to those that came before me, "all that is old is really new" ++++++++++++++++++++++++++++++++++++++++++++++ I keep a set or two of the Altenburgers around both because they are interesting, and because occasionally they solve a real problem. For example, they were the cat's meow for getting decent braking on a first generation Moulton small-wheel bike, where the rear swing-arm really didn't have clearance for a good (long-reach) a side-pull, and at both ends, where movement of the suspension made rigging centerpulls really difficult. The Moulton was sold with classic British sheet-stamped side-pulls, one step up (maybe) from the old push-on-the-tire rod brakes. But I'm not prejudiced or anyting.
Besides working, the Altenburger dual-pivots have an enormous coefficient of funk, routinely blowing the minds of newbies. :-)
