Bontrager RSL 20mm Setback Carbon Seatpost

Strong, light and with an updated ergonomic design, the Bontrager RSL 20mm Setback Carbon Seatpost utilises a new design profile to offer more control, vertical compliance and increased torsional resistance.

Constructed using Bontrager’s OCLV carbon material throughout, weight is kept to a minimum, while the overall structure delivers a more forgiving ride. The seatpost has a diameter of 27.2mm with a 20mm offset from a regular neutral position for riders who need that extra space. Custom adjustability is obtained using the 2-bolt design allowing independent setback and tilt movement.
