All product codes are the KS codes to make it easier.
All seatpost diagrams and dimensions are listed in the specific model page.
If ordering item # P1029 which is the mast end sleeve please check the diameter of the pushrod cap, this is a modified end and the new cap is 4mm in diameter.
See the information on the pushrod cap chart.
For warranty claims, we need the following information: Serial number off the mast of the seatpost starting with either OE or AM followed by 9 digits and a proof of purchase.
Please use the correct receipt, we have seen claims rejected because when they check the serial number against the POP the date indicated the post was not yet available.
