{"product_id":"hope-seat-clamp-qr-collier-de-selle-blocage-rapide","title":"HOPE SEAT CLAMP QR quick-release seatpost clamp","description":"\u003cp\u003eThe Hope Seat Clamp QR adjusts saddle height without tools. Its lever, redesigned by Hope, is easier to operate, and an IGUS bushing gives it a smooth action that needs little maintenance. The spherical-seat bolt spreads the force over a wide clamping area: the post isn't damaged, and a dropper post keeps working.\u003c\/p\u003e\u003cp\u003eThe diameter is chosen from the frame's seat tube, not from the seatpost: Hope requires a tube within ±0.5 mm of the clamp size. With the lever closed, the bolt is set to 5 N·m with a 4 mm key, slightly less if the dropper post no longer slides freely.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003e2014 T6
