Bontrager Rotary Head Seatpost Saddle Clamps

These clamps are specifically designed for Bontrager saddles with carbon rails. If you are using a different brand, we recommend checking with that manufacturer to ensure their rail dimensions and shape are compatible with these specific rotary head clamps.

You must match the clamp size to the specific rail dimensions of your saddle. Check your saddle's technical specifications or measure the rail diameter directly to ensure you select the correct size for a secure fit.

While these are optimized for Bontrager and Trek rotary head seatpost and seat mast systems, they are also suitable for certain straight seatpost configurations. Verify your specific seatpost head design before purchasing to ensure the clamp interface matches.

These saddle ears are constructed from carbon fiber to provide a lightweight, durable interface for your saddle rails. They utilize steel bolts with an Allen head for a reliable, secure bolt-on connection.

This kit includes the replacement saddle ears required to secure the rails. It does not include the entire seatpost assembly, so ensure you have your existing seatpost hardware ready for the installation process.
