Make sure you measure the outer diameter of your frame's seat tube. Don't just go off your seatpost's markings.
Seatpost collars are the little strongmen of bike components. Weighing only a few grams yet capable of holding a riders body weight over all types of terrain, without any fuss, for mile after mile. The size of collar depends on the diameter of the seat tube of your frame. Merlin stocks seatpost collars from Hope, Thompson and BBB.
