Stop for a moment and think about the scratching sound that comes from your seat tube when you adjust the height of your seatpost. Little particles of dirt, dust, moisture, maybe the remnants of an energy bar and such, moving around inside the tube. You want to get rid of that? Quite simply, with the sealed saddle clamp. This seat clamp has an integrated seal that prevents dirt and water from entering the frame by sealing the seat post and tube. Nothing fancy, but it works perfectly.

The sealed saddle clamp is available in two different sizes. One is compatible with 34.9mm seat tubes and 31.8mm seat posts and the other with 36.4mm seat tubes and 31.8mm seat posts.
