Rolling Chassis - Dropper Post Length

OneUp Components V3 & V2 Dropper Post

Dropper Drop Options - 150mm, 180mm, 210mm, or 240mm

Rolling chassis come with a choice of OneUp dropper posts, each with a different drop amount. We always recommend choosing the biggest amount of drop possible. More drop is more better.

That said, not all dropper posts will be able to fit in all frames. Below is a table showing the minimum seat height for a given frame size and drop amount.

In order to determine which amount of drop you can fit on your Madonna V2.2 or Jibb, simply measure the distance from the centre of the bottom bracket to the saddle rails on your current bike, with your dropper fully extended. Check which bike you’ll be going for and in what size, then see in which drop fits your saddle height.

For example, if your current bike has a distance of 645mm, and you’re looking at a Madonna V2.2 in size M, it’s above the minimum distance for the 150 mm drop post (603 mm), meaning that post will work for you, but it’s under the minimum distance for the 180 mm drop post (659 mm), meaning that one won’t work.

The OneUp droppers come with two shims included in the box, which can reduce the drop of the post by 10 mm or 20 mm. This will only affect the upper limit of the range, while leaving the minimum distance unaffected.

If you're unsure about the right choice, feel free to contact us directly. You can reach us by email at hello@raawmtb.com or by phone. We're here to help and we'll do our best to answer your questions.
