{"title":"Seatpost clamps","description":"\u003cp\u003eThe clamp tightens the top of the seat tube around the seatpost. Choose it by the outside diameter of the tube, not the post, then bolt-on to hold or quick-release to adjust the saddle without tools.\u003c\/p\u003e\u003ch2\u003eMeasure the tube, not the post\u003c\/h2\u003e\u003cp\u003eIt is the most common mistake: a 31.6 mm seatpost does not need a 31.6 clamp. The clamp goes around the frame's seat tube, whose wall adds a few millimetres. So measure the outside diameter of the tube with a calliper, just below the current clamp. Hope requires a tube within 0.5 mm of the clamp size, and makes its clamps in seven diameters, from 28.6 to 39.7 mm.\u003c\/p\u003e\u003ch2\u003eBolt or quick-release\u003c\/h2\u003e\u003cp\u003eThe \u003ca href=\"\/en\/products\/hope-seat-clamp-bolt-seatpost-clamp\"\u003eSeat Clamp Bolt\u003c\/a\u003e clamps with an M6 stainless bolt and a spherical-seat nut that self-align: it is the clamp you fit once and for all, on a rigid or dropper post.

Its lever pivots on an IGUS bushing that needs little maintenance. The honest downside: a saddle on a quick-release also comes off without tools.

Beyond that, you crush a carbon post or ovalise the body of a dropper post like the \u003ca href=\"\/en\/products\/ks-lev-ci-dropper-post\"\u003eKS LEV Ci\u003c\/a\u003e, which starts to stick. Hope gives 6 N·m for the bolt version, 5 N·m with the lever closed for the quick-release, and slightly less if the post no longer slides freely. For a carbon post that slips, carbon assembly paste is better than another turn of the key. \u003ca href=\"\/en\/collections\/seatposts\"\u003eSeatposts\u003c\/a\u003e give their own maximum torque in their specifications.\u003c\/p\u003e","products":[{"product_id":"hope-seat-clamp-bolt-collier-de-selle-a-vis","title":"HOPE SEAT CLAMP BOLT bolt-on seatpost clamp","description":"\u003cp\u003eThe Hope Seat Clamp Bolt clamps the seatpost with an M6 stainless bolt with a spherical seat, and its nut.
