Saddle Height Insert for Brompton Bicycle's

If you do not like your seat post at the maximum height, you can use these inserts to set the max height your saddle will go. This way, you do not have to fine tune your seat height every time you unfold your Brompton.

Brompton does sell saddle heigh inserts and you cut them down to the height that you want. They are a one shot deal. Once you cut them, you can't make them longer again. Also, Brompton dealers may not have in stock and you have to wait for them if you order.

These inserts, you can just print the height that you want, no cutting required. You can print a few different sizes and test them out.

I have found when I got new shoes, my saddle height was no longer perfect (soles of shoes were much thicker). No problem, I just printed off a new insert. In winter, I generally wear winter shoes, again, different size sole … just pop off a new insert.

I have precompiled inserts from 10mm to 50mm in 5mm increments. If you want something more specific, leave a comment and I will compile and post the custom size for you.

Printing Instructions:

I printed my prototype in PLA. It worked just fine. I printed my final version in ABS.

I used 4 walls, 30% infill which worked great.

Print standing up. No supports required.

Happy Riding
