The 118.5mm spindle is the road triple length, making this the correct match for FC-6503, FC-5503 and equivalent Octalink V1 triple cranksets. A straightforward, reliable BB that just works.<\/p>\n<p><strong>Workshop Wisdom<\/strong> \u2014 Octalink V1 and V2 are not interchangeable \u2014 V1 has a 5mm deep spline, V2 is deeper.
