The 53\/39 on 130mm BCD is the classic road double setup, and 172.5mm is the most common arm length making this a straightforward drop-in for a wide range of riders. Solid, proven, and a natural fit for any period-correct 8 or 9-speed Shimano road build.<\/p>\n<p><strong>Workshop Wisdom<\/strong> \u2014 Octalink V1: torque crank fixing bolt to 35\u201350Nm, splines clean and dry, grease on bolt threads only. Do not confuse Octalink V1 with Octalink V2 \u2014 not interchangeable.
