We offer dropper post lengths in 10mm increments from 160-240mm. Maximising drop length for your saddle height is important to get the most out of your bike. With different seat tube and post lengths, insertion depths and drop lengths to consider, it can be tricky. So we've put together a handy guide to help you choose.
To understand your saddle height, measure your current bike from BB centre to saddle rails in mm. Then compare that measurement to the chart below to identify the best drop legth for your Filter MX frame size.
| 160 | 170 | 180 | 190 | 200 | 210 | 220 | 230 | 240 | |

| S4 | 652 | 662 | 672 | 682 | 692 | 702 | 712 | 722 | 732 |
Things to consider
The Filter MX full builds come with a 165mm crank, so if the bike you're used to has longer cranks, factor that in. Saddle height is also affected by your choice of saddle, pedals and even shoes. We've built a margin into the advice in the chart so that you'll have room to go up or down if necessary.
