When you spent a ton of money on your bike frame, investing 25€ more to protect its insides is not that bad of an idea, is it?

Hold on for a second and think of the scratching sound that comes out of your seat tube when you adjust the height of your seat post. Little pieces of dirt, dust, moisture, maybe some bits of an energy bar and whatnot that are being moved around inside of the tube. Want that gone? Here‘s all you need: The Sealed Seat clamp.

Seems too simple? Too good to be true? Too obvious? Well, we thought so too at first. We asked ourselves: If it really is that simple, why doesn’t everyone already have it on their bike? We went along and made it anyway. And as it turned out, it actually is that simple.

This seat clamp has an integrated seal that prevents dirt and water from entering the frame by sealing seat post and tube together. The special single-screw clamp is CNC-milled from 6061-T6 Aluminum and entirely made in Germany - because we’d be hypocrites if we got our hands dirty while keeping the inside of your frames clean. The dust- and splash-proof seal is made from TPE rubber and can be shortened to match various bike frames. Best sealing performance is achieved with bike frames with one clamp gap.

The Sealed Seatclamp comes in 2 different sizes. One is compatible with 34.9 mm seat tubes and 31.6 mm seat posts and the other one with 36.4 mm seat tubes and 31.6 mm seat posts. There are two colors to match any bike out there: Midnight Black and Raw. Nothing fancy, but it works perfectly.
