Wondering which shock length is right for your Starling Cycles frame?
Wonder no more! Here’s your complete guide with, hopefully, everything that you need to know.

Starling Cycles Adjustable Shock Lengths
Starling Cycles full suspension frames have an adjustable shock mount. This was introduced for V3 and allows us to adjust the frame to accommodate different shock lengths.
By moving the shock mount and using different-length shocks, we’re able to change the travel of our frames.
For example, a Murmur frame can be adjusted in this way to have 120mm, 135mm, 150mm or even 165mm. Note: 165mm requires a different swing arm.
Note: The shock change in itself doesn’t change the geometry of the frame. But if you pair a similar travel fork with the frame, the geometry is corrected for the frame’s intentions. A longer fork slackens angles, a shorter fork steepens them.
Setting Up Your Adjustable Shock Mount
Ready to setup your adjustable shock mount?
This is straightforward, but, requires a little bit of understanding.
All frames purchased with shocks and complete bikes will come setup, so no effort required. But, if you’re changing shocks or fitting your own you’ll need to know how to do it.
Watch this video and Joe will explain how to do it:

Starling Cycles V2 and earlier frames
And how about shock compatibility for older frames?
Second-hand owners may find themselves with frames that don’t have a sliding shock mount.
For these, the best thing to do is to contact us and include the frame number, as found on the dropper port. We can check the history of the frame and let you know which shock length is best for you.
