Shimano FC-6700 Ultegra 10 Speed Double Chainset 172.5mm 39/53T

Industry leading HollowTech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight and improve strength

HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load

The chainring teeth have been developed to work in conjunction with the CN-7900 and CN6700 chains for increased contact to provide greater efficiency and improved power transfer

HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency

HollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability
