Bontrager RSL Seatpost

The Bontrager RSL Seatpost has a 27.2 mm diameter and a 400 mm length. You should verify that your frame specifically requires a 27.2 mm post, as this is a standard size for many road and gravel bikes but not universal.

No, this seatpost is designed for saddles with standard 7x7 mm round rails. If you have a saddle with oversized carbon rails, you will need a different clamp system or a compatible seatpost.

The CnD shape profile is engineered to provide a dual benefit: it increases torsional stiffness for efficient power transfer while offering vertical compliance to absorb road chatter. This helps smooth out rough surfaces without sacrificing handling precision.

The two-bolt design allows you to adjust your saddle tilt and setback independently. By loosening or tightening the bolts in specific combinations, you can fine-tune your position with much greater precision than single-bolt systems.

Yes, it is designed for both road and gravel applications. The OCLV carbon fiber construction is specifically built to provide vibration damping, which is particularly beneficial for smoothing out gravel chatter on longer rides.
