Compatibility Guide
SwitchGrades come in 3 models and five (5) configurations or "Types" - each designed to be compatible with a specific range of seatposts. Be sure to select the correct Type (Type 1, Type 2, Type 3, Type 4 or Type 5) from the drop-down list.
IMPORTANT NOTE: The provided table is strictly a fitment and compatibility guide. The model year shown in brackets below only indicates the model year of the particular seatpost that was tested for fitment compatibility. SwitchGrades feature a universal design and may be backward and/or forward compatible, but unless indicated, we cannot guarantee whether a particular seatpost model year is compatible with respect to fit. All compatibility and fit determinations have been observed solely by Aenomaly Constructs. Use of a SwitchGrade may void any warranty a User has with the original part manufacturer. Ultimately it is the User's responsibility to satisfy themselves on whether a seatpost and/or saddle, whether individually, or in combination, will be compatible with a SwitchGrade.
NOTE: If you do not see your fixed or dropper seatpost listed in the table we cannot confirm compatibility. That is not to say your seatpost is not compatible, we just have not investigated compatibility yet. Our definition of "compatible" is limited only to fit and installation on a noted seatpost. Certain combinations of frame seat tube angle, seatpost head design, and desired tilt may work better on one frame vs. another. You may also require a Shim. Please read Notes carefully.
