Seat clamps fit for a king! Only if the king’s frameset runs 31.8 or 34.9 clamp diameter though! From our Korean friends over at Punchblues, often imitated, never duplicated. Fits your seatpost cleanly
The King Clamp wraps a 27.2mm seatpost in a 31.8mm collar, or a 31.6mm post in a 34.9mm one, so the fit feels direct instead of fussy. You get a snug hold for the saddle height you set and leave alone.
Holds with a neat finish
Its compact seatpost clamp shape keeps the frame line tidy, and the finish reads crisp in black, Champagne Gold, Yellow Gold, or blue. The metal surface has a smooth, worked look, the kind you notice when the bike is leaning against a wall at the cafe or loaded for a quick ride across town.
Choose the size that matches
If your bike uses a 27.2mm seatpost, reach for the 31.8mm version. If it takes a 31.6mm seatpost, pick the 34.9mm clamp. Simple. The right collar settles in without extra guesswork, and that matters when you just want to set the saddle, tighten it down, and get rolling.
