These reducer sleeves ensure your bicycle saddle fits perfectly, regardless of the diameter of your seatpost. With three different thicknesses (0.3, 0.5 and 1 mm), you'll always find the right size for a secure fit.
When do you choose this product?
What do bicycle seatpost shims do?
Bicycle seatpost shims are reducing sleeves you can use when your seatpost is too thin for the seat tube of your bike. They fill the gap between the seatpost and the seat tube.
Why choose this 25.4 mm variant?
This set is designed for all seatposts with a diameter of 25.4 mm. If your seatpost has this size but does not fit properly in your bike frame, these shims are intended as a supplement. They are suitable for seat tubes with a diameter up to 29 mm.
Flexible adjustment with reducing tubes
The set contains three reducing tubes of 0.3 mm, 0.5 mm and 1 mm thickness. The tubes can also be combined, so you can adjust the fit.
Practical fitting tip
First measure the diameter of your current seatpost and seat tube frame to check whether this set is suitable. Install the reducing tubes one at a time and test the fit. Start with the thinnest tube and add thicker tubes if needed until your seatpost fits firmly but not so tightly that it is stuck in the frame.
