Yes, some rotational movement is normal in the our dropper posts. With so many different frames, clamps, tolerances, and ride heights it's not possible to ship play-free, without running the risk of binding, as all dropper posts require keyway clearance. This small amount of movement, although noticeable in the stand, with not be perceivable while riding. If you are finding you have more movement that preferred, or additional movement is developing over time we have the Oversized pin kit to tune this movement out of you post. Most setups do not require the additional spacing of the oversized pins, but we can definitely provide them if required. Please email support@oneupcomponents.com for assistance.
