• Bottom Bracket Cable Guide - 1 Nm
• Brake / Shift Levers - 5 to 8 Nm
• Brake Calipers - 8 to 10 Nm

  • Carbon Two Offset Seatpost (S5) saddle clamp bolt - 12 Nm (Note that two Allen keys are required to prevent the bolt from turning while applying the proper torque; this must be verified using a torque wrench. Insufficient torque will cause the saddle to slip, possibly causing premature wear to the clamping mechanism.)
