Compatibility Guide

IMPORTANT NOTE: The provided table is strictly a fitment and compatibility guide. The model year shown in brackets above 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. 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, however, we just have not investigated compatibility yet.
