IMPORTANT
To ensure that your PressFit GXP ROAD or MTB Bottom Bracket performs properly and to help make your riding
experience more enjoyable and trouble-free, we highly recommend that you have it installed by a qualified bicycle
mechanic. Installation of the adapter does not have to be permanent. However, removal of the adapter can damage
the cups and bearings. Do not re-use the adapter after removal from the frame shell. The adapter will only work in
undamaged frames in good condition. The adapter must NOT be used as a way to repair frames with damaged press
fit bottom bracket shells. Improper use, installation or removal of the adapter will void your warranty and can void the
warranty for your frame.
