Shimano Ultegra 6700 Chainset

Shimano Ultegra FC-6700 Chainset

First they introduced HollowTech cranks. Now Shimano offer an Ultegra chainset with a Hollowglide outer chainring.

• The Hollowglide chainring is more flex-free chainring without any weight penalty.
• Industry-leading HollowTech II cold-forged hollow crank arms increase rigidity, reduce weight and improve strength.
• The system's integrated bottom bracket's wider bearing placement and larger diameter axle improves stiffness, longevity and efficiency.
• This integrated bottom bracket is designed to minimise contact between seals and bearing and contributes to the system's smooth-spinning long-life performance.
• Chainring rigidity improves gear shifting performance under high load.
  
• The new chainring teeth profile was developed to work in conjunction with Shimano CN-7900 and CN6700 chains to optimise chain/chainring contact for optimal efficiency power transfer.
• Manufacturer's published weight: 785g inc bottom bracket.
