Seatpost

All models use a 34.9mm seat post and a 38.6mm seatpost collar (S184700004).  The clamp bolt should face forward and be torqued to 6.2Nm (55in/lbs).

When adjusting the saddle height or installing an aftermarket dropper post, it is important to ensure the insertion depth is within the acceptable range. 

The Alloy and Carbon frames have different seatpost minimum and maximum insertion requirements. Check the table below that applies to your frame.

The Stumpjumper carbon frame requires a minimum seatpost insertion of 80mm. Maximum insertion is size-specific. The frame is designed for a 34.9 seatpost and 38.6mm clamp. Torque the seat clamp to 55 in-lbf (6.2Nm).

The Stumpjumper Alloy frame requires a minimum seatpost insertion of 100mm. Maximum insertion is size-specific. The frame is designed for a 34.9 seatpost and 38.6mm clamp. The clamp bolt should face forward and be torqued to 6.2Nm (55in/lbs).
