Velo Orange - Grand Cru Disc Touring Hub 135mm 36h Sadel Both cups are made ofThe Grand Cru Touring Hubs, designed for long distance cycling and heavy loads, are now available in this disc version. The high flange hub shell is our own design. The high flanges allow for four identical and fairly large cartridge bearings. These large bearings would not have fit in a regular low flange design. We continue to use very high quality Japanese cartridge bearings. These cost us 5 to 10 times as much as the bearings in many other hubs.
