Hereby I would like to show you a very nice front hub. What makes it special is that the flange width is 82mm from outside to outside which makes the front wheel extremely stiff and strong.
"Introducing the Alchemy E.L.F. (Extra Light Front) front hub (pictured
above). This hub uses a 6900 series bearing. The 6900 bearing has a thicker
cross section and uses larger balls than the super thin-section 6800 series
bearings commonly used in other lightweight hubs. Consequently, the load
capacity of this bearing is higher than that of any bearings used in other
ultra-light hubs (I consider 80g as a cut-off for "ultra-light"). In addition, the
Alchemy hub comes standard with Abec 5, grade 5 ceramic hybrid ball
bearings. The Alchemy hub weighs 64g-65g depending on the hole count.
The flanges are angled at 6 degrees and the flange width is 82mm from
outside to outside. The wide flange placement produces a better bracing
angle than is common, which adds significant strength and stiffness to the
finished wheel. In addition, the bearings are positioned extremely far apart
(94.5mm from outside edge to outside edge). The distance between the
dropout and the bearing acts as a lever arm. Design on this hub reduces this
dimension to 2.75mm compared to the more common 10mm-15mm distance.
As a result, axle bowing and flex is virtually eliminated. This contributes to
increased bearing life and to lateral stiffness of the wheel. "
1 front hub costs 160 Euro
