RIRO SP6 Carbon Fiber Seatpost Features and Specifications

The RIRO SP6 Carbon Fiber Seatpost uses a high-modulus full carbon construction that cuts weight without compromising the lateral stiffness road and MTB riders depend on during hard efforts. At 400mm in length, it offers generous insertion depth suitable for a wide range of rider heights and frame geometries. Three diameter options — 27.2mm, 30.9mm, and 31.8mm — cover the most widely used road and mountain bike frame standards, so you can upgrade without sourcing an adapter. The layered carbon tube naturally damps high-frequency vibration from rough pavement and gravel, reducing fatigue on long rides without the flex penalty of alloy alternatives. A precision-machined alloy head clamp with dual-bolt adjustment allows fine saddle angle tuning, giving you a repeatable, locked-in position every time you set up the bike.

5 reviews for RIRO SP6 Carbon Fiber Seatpost 27.2/30.9/31.8mm 400mm Ultralight Road MTB

  1. s***r –

    the diameter was slightly larger in some places

  2. P***u –

    Package was damaged upon arrival. No protection, but nothing was broken.

  3. AliExpress Shopper –

    You put it at 30.9 and then send 30.8, telling me to use it? The Giant specifications and Specialized specifications are clearly different, aren’t they?

  4. AliExpress Shopper –

    Thomson design, excellent quality.

  5. AliExpress Shopper –

    The advertisement states 31.8mm, but the seller delivers 31.6mm, and that’s it. If I buy a different size, I have to be very careful. Then you request a refund, and the amount offered is much lower.
