The chrome-moly steel axle and Octalink splined interface create a rigid crank-to-spindle connection that resists the flex that comes with explosive, single-gear efforts on the track.\u003c\/p\u003e\n\n  \u003cp\u003eWhere this bottom bracket separates itself is in the bearing arrangement. A compound structure combines ball bearings and needle bearings within the same unit — needle bearings to manage radial loads, ball bearings to handle axial loading. Each type does what it does best, and together they support the spindle with a durability that's designed to hold up under sustained, high-power output.\u003c\/p\u003e\n\n  \u003ch3\u003eShimano Dura-Ace BB-7710 Track Bottom Bracket Specs at a Glance\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShell compatibility:\u003c\/strong\u003e 68mm BSA (English thread)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpindle length:\u003c\/strong\u003e 109.5mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAxle material:\u003c\/strong\u003e Chrome-moly steel\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInterface:\u003c\/strong\u003e Octalink splined\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 230g\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cp\u003eNote: crank arm bolts and dust caps are sold separately.
