MAX posts have an upper tube that is sized to match the 34.9mm lower, creating more stiffness and smoother actuation. Self-serviceable dropper post with reset lever at the head. Updates for version 3 include new saddle clamps for a 5mm lower stack height and a 360A rotatable foot unit shortens the overall length of the seat post by a further 10 mm. These changes result in a shorter stack height for the same drop lengths. Non-IFP design provides better reliability and extremely smooth action. Remote not included. Use YB210*. All Revive posts feature internal and front feed cable routing. Maximum rider weight limit (fully equipped) of 115kg (250lbs). 3rd party web sales (eBay, Amazon, etc.) are strictly prohibited by the manufacturer
