I have the HS-66 Magura hydraulic rim brakes on my Burly tandem. They are the best stoppers I have ever owned on a bicycle. Magura doesn't make the drop bar version anymore. The HS-33 brakes are still the favorite of many world travelers. I wish I had ordered my custom touring bicycle with the canti/V brake studs instead of the disk brakes. I may still send it into Co-Motion and pay them to put the canti studs and some hydraulic cable guides on.
