The Glagol SL9 is a lightweight seatpost precisely shaped to fit the unique seat tube profile of the Specialized Tarmac SL9. It brings the same proven performance and engineering as our original Glagol seatposts, while guaranteeing seamless integration with your frame.

As with all Bjorn seatposts, the Glagol SL9 uses a wide carbon clamp that spreads load evenly across the saddle rails. This prevents damage and ensures reliable fastening, whether you ride carbon or metal rails. The clamp bolts can be flipped for easy access and installation, even with saddles that have a cutout.

All Glagol SL9 seatposts come with a mounting holes on the bottom to fit a Shimano Di2 battery holder.

We produce the Glagol SL9 in both zero-offset and setback versions, using the same structural design.

Note: Please check the layup scheme before selecting the length of your Glagol SL9 seatpost. Each length has its own optimized layup to minimize weight. The reinforced clamping zone is limited to the section below the max insert line sticker.
