I like the Duplex, and have been hoping to find one used for sale. There is one on e-bay right now. BUt I just bought a Troika Trike so I've spent all my free bike cash... I have had the screamer for about 8 years and for the most part it has been a very good bike, but I do find that I like under seat steering more then the above seat. I may even build a underseat steering for the screamer.

But... could you give me the contact for the duplex owner? Like Ive said I always wanted a Duplex

The "supplemental drum brake" is for use on long downhills. If you use your rim brakes to control your downhill speed the heat built up in the rims will cause the tires to fail (melt) Any tandem used for touring should be equiped with a drum brake. The drum brake keeps the heat away from the tires. how much heat? I ve set the grease on fire in the hub on the Screamer riding down route 2 into Greenfield Ma. So if your planing on any loaded tours the drum brake is a real plus. Disk brakes are nice but not up to the heat that is built up using them as a drag brake, Ive cooked most of the disk brakes out there
