RIDEA - QR Seatpost Clamp (Dahon) 快拆座管扣 系列

Choose between the convenience of a quick release system (SCQR) or the extra safety of a bolt-on system with models with two bolts (SCDL). In addition, SCDD is a dual bolt-on seatpost with two special characteristics: first, it has a plate holder for your racing number; second, it has a double diameter to clamp both to the seat tube and the seatpost for extra resistant to sliding down.

Important note: Ridea seatpost clamps are sized based in the seat tube diameter of the frame. To find the right clamp size for your frame, please measure the diameter of the seat tube in the clamping area for the seatpost clamp.
