Bontrager Pro Seatpost

Yes. The unique clamp design is engineered to accommodate both standard round metal rails and oversize carbon saddle rails, so you don't need to worry about compatibility when upgrading your saddle.

It is built for both. The combination of the OCLV carbon fiber shaft and the forged 6061-T6 alloy head provides the durability required for trail riding while remaining light enough for road performance.

The 2-bolt system allows you to independently adjust the angle of your saddle by tightening or loosening the front and rear bolts. This gives you 15 degrees of fine-tuning, making it much easier to dial in your preferred position compared to single-bolt designs.

You must match the seatpost diameter exactly to your bike frame's seat tube inner diameter. You can usually find this measurement printed on your current seatpost, or you can check your bike manufacturer's specifications online.

The offset refers to how far the saddle clamp sits behind the center line of the seatpost shaft. A 0mm offset keeps the saddle centered for a more aggressive, forward-leaning position, while a 15mm offset pushes the saddle back, which can help riders who need more reach or prefer a slightly more relaxed geometry.
