 ====Die Maillard Helicomatic Nabe====
-DESCRIPTION
+[[Datei:Helicomatic.jpg|center|Maillard Helicomatic Nabe mit passendem Werkzeug]]
-Some French bicycles (and many early Treks!) came with Maillard "Helicomatic" rear hubs. This was the first cluster that could be removed without a big, powerful tool. It came with a cute little pocket-size tool that incorporated a spline wrench for the cassette lockring, a spoke wrench, and a bottle opener. The Helicomatic was a nice idea on paper, but poorly executed. These hubs are losers.
-Both hub flanges were 1mm farther to the left than those of a normal hub, causing increased dish in the rear wheel, and persistent spoke breakage problems. Many loyal Helicomatic fans tout the ease with which the cassette may be removed for spoke replacement as a great virtue, but if the hub were better designed, it wouldn't break so many spokes!

-These hubs were prone to bearing problems as well. Due to clearance requirements, they couldn't fit the normal 9 1/4" bearing balls, so they used 13 5/32" balls on the right side. These didn't hold up well. The cones tended to wear rapidly, and replacement cones are no longer available to fit these hubs.

 Most of the French bicycles that flooded the U.S. in the '70's had plain rear fork ends, and used rear derailers with bolt-on adapter claws, secured by the rear axle.
