Description 11-speed for the masses. This 2011 Athena crankset delivers performance oriented features with the classic look, durability and budget-friendly price of an aluminum design.
An affordable price tag is only the beginning; the updated Athena crankset features Power-Torque technology with a full length spindle integrated into the right crank arm. This design eliminates the mid-shell hirth bolt of last year's model, simplifying the installation process while ensuring an incredibly rigid ride quality. The drive side bearing is integrated to the crank, while the non-drive side bearing is included with the bottom bracket cups (available separately). Improved seals stand up to inclement weather, keeping out contaminants and increasing bearing life. Q and U factors have been optimized for comfort and efficient power output.
The XPSS™ (eXtreme Performance Shifting System) is also new for this year- redesigned chainring tooth profiles and updated shift guide pins offer improved chain engagement for lightening fast, accurate shifting in both directions. Available in Standard (53/39) or Compact (50/34) configurations.
Compatible with 11-speed systems only. 723 gram claimed weight. Requires Power Torque Bottom Bracket Cups (sold separately ).
