Set-up / Tips

Use the carbon paste on the lower section of the post in the frame to eliminate slippage. Also it can be helpful to put some on your seat post rails and on & under the lower clamping bowl. A small tub is supplied.

Take note the best direction for clamping in the photo of saddle rails, the supportive aluminium rail clamping part is best pointing inwards.

There is no specific torque recommendation for the bolts.  Tighten them to the point where you feel confident nothing will slip, but not crazy tight. Common sense here.

The minimum insertion from the bottom of the post into your frame is 10cm.  There is no maximum insertion limit from the top.
