REDSHIFT Dual-Position Seatpost Black/Red

The REDSHIFT Dual-Position Seatpost allows you to quickly switch from a road position to an aerodynamic position on a standard road bike. Its patented Dual-Position Quick Adjust mechanism moves the saddle 50 mm forward to adopt a posture better suited to long fast sections or time trial events, without altering the bike's usual setup.

Thanks to its articulated linkage system, changing position is easy whilst riding. This design maintains consistent leg extension in both configurations and provides a modified effective seat tube angle of approximately 3 to 4 degrees. The road position is thus preserved for climbs and descents, whilst the forward position promotes a more aerodynamic posture on flat sections.

Made from 6061-T6 aluminium with linkages and carriages in 7075-T6 aluminium, this seatpost prioritises stiffness, reliability and durability. Its dual-bolt clamp allows precise saddle tilt adjustment and ensures secure rail retention during intensive rides.

Compatible with saddles fitted with 7 mm round rails, the REDSHIFT Dual-Position Seatpost is a practical solution for transforming a road bike into a versatile machine, capable of alternating effectively between comfort, efficiency and aerodynamic performance without changing bikes.

Is there a risk of the saddle accidentally tilting while riding? No. The mechanism incorporates a very firm mechanical lock. To change position, simply relieve some of your body weight and push or pull the saddle.

Can it be fitted to a frame with a 30.9mm or 31.6mm seat tube?Yes, the post is the standard diameter of 27.2mm. Simply use a dedicated seatpost shim (Redshift Seatpost Shim) to fit it to wider frames.

Is it compatible with handlebar extensions? That's its ideal pairing! Used in conjunction with the Redshift Quick-Release Aerobars, it allows you to transform a standard road bike into a true triathlon bike in a matter of seconds.
