The world’s lightest pulley wheels

The delicate Carbonice "Hanni und Nanni" guide rollers are almost manufactured entirely out of Carbon. In order to guarantee long lifetime of the product, ceramic hybrid ball bearings were used with gaskets at both sides. The upper roller is specifically reinforced  for to fully absorb and transfer the axial and lateral forces. The bottom roller on the other hand is much more lightweight because it has to only maintain the chain tension so that it takes only the radial forces. "Hanni und Nanni" - with 11 cogs - can be used for all 9, 10 and 11 times cogsets.
