The 107-gram carbon saddle with a cork pad

Bjorn Saddles
Bjorn Probka Cork Saddle

The Probka tops Bjorn’s carbon shell with 8 mm of cork, a natural material that damps road vibration and shapes itself to you over time. At 107 grams, it’s the lightest of the four Bjorn saddles we carry.

More about the Probka

Cork is a natural cushioning material with excellent damping, so it smooths out road vibration while keeping power transfer direct. It also deforms under your pressure points over time, so the pad adjusts to you and the contact area grows.

The pad is 8 mm thick, with a pressure-relief channel at the front, and Bjorn impregnates it with a compound that protects it from moisture, salt and UV. Underneath is Bjorn’s carbon shell, with carbon rails that are inserted into reinforced slots instead of being glued.

The cork isn’t made for hard impacts, and Bjorn’s warranty doesn’t cover damage to the pad from a fall.

How does cork hold up? add
Bjorn points to cork’s use in shoes, furniture and aerospace as evidence of its durability, and treats the Probka’s pad against moisture, salt and UV. The pad deforms under your pressure points over time, which is the idea: it adjusts to the rider. What it won’t take is a hard hit, and damage to the pad from a fall isn’t covered by the warranty.
Will it fit my seatpost? add
The rails are oval carbon, 7x9 mm, so your seatpost clamp needs to be made for 7x9 rails. A clamp made only for round 7 mm rails isn’t suitable. Many posts take them as standard and others need a different clamp. If you’re not sure about yours, ask us before you order.
