Unfortunately we have not tried it specifically to see if it would work. Typically with a full suspension frame, we will always error on the side of wider than narrow. For specific sizing advice, I would suggest contacting Yeti directly as they would most likely know what the minimum Q-factor is for their bikes. Their phone number is 888-576-9384. If you have any additional questions feel free to let me know.
