If everything in your seatpost is working well, except you notice a little friction in the post, it may be time for a new seatpost pillar. Because our seatpost uses brass keys to keep rotation to an absolute minimum, the inevitability is wear within the pillar.
TRS post is discontinued but service parts are still available.
Compatibility
Works in both 30.9 and 31.6 seatposts Correct length and version (V10 through V15) needs to be selected
