Nabenschaltungstheorie: Unterschied zwischen den Versionen

Zeile 67: Zeile 67:
Both Sturmey-Archer offers three-speed hubs with splines to fit a Shimano-standard cassette, for multi-speed hybrid gearing. These hubs eliminate the need for a front derailer and are especially suitable for small-wheel bicycles: the step-up top gear avoids the need for an oversize chainwheel. SRAM used to offer these hubs.
