Seatpost Adapters



Our Seatpost Adapters quite literally fill the gap, with over 25 sizes available, the combinations are endless. These Seatpost Adapters are compatible with static, suspension and dropper Seatposts

Quality Material

Not all seatpost adapters are created equally. Our Seatpost Adapters are made of premium quality aluminum and have been manufactured within stringent tolerances to match or surpass the highest quality standards. Our premium manufacturing ensures that these seatpost adapters won’t scratch the post.

Compliance

Our Seatpost Adapters provide the opportunity for riders to tune and adjust the compliance of their ride. By swapping the original seatpost for a post with a smaller diameter, riders are able to maintain the advantages from a strong rigid frame while simultaneously creating a smoother ride.

Apart from MTB, can this shim be used on Fat bike, BMX or Folding bike? Carlos asked on November 23, 2023

They can be used on any bike with a round seat tube, so long as the dimensions line up!

The internet seems to indicate that it is possible but I wanted to ask the manufacturer: Can 2 shims successfully be stacked? i.e. to fit a 27.2 seatpost to a 34.9 seat tube or would it be better to source a larger diameter seatpost and only use one shim to fit 34.9 seat tube? ETHAN N BAKKEN asked on November 7, 2023

You should only use one adapter when fitting a seatpost to a larger seat tube. If you need a 34.9mm seat post, choose the 31.6mm seat post, and the 31.6mm-34.9mm seatpost adapter.

Can I use a 27.2 to 31.6 adapter to fit an 27.2 eeSilk seatpost onto a 31.6 diameter seat tube? Stefan asked on September 13, 2023

Yes. Our seatpost adapters are designed to allow smaller seatposts, to fit into larger seat tubes. Just make sure you choose the correct shim for both your seatpost diameter, and the seat tube.

I had tube measured with a drop in taper gauge and it measured at 26 mm. The seat post was stamped as 25.4. The shim was too big… I used an aluminum can.
