Compatibility Compatible with bike frames that use 30.9mm or 31.6mm diameter seatposts with internal cable routing for dropper posts. A 31.6mm diameter post with a seatpost shim can be used for bike frames that use 34.9mm diameter seatposts. Shims are NOT included with the seatpost. The minimum insertion depth is clearly marked on the Resolve Dropper Post lower tube and varies between 90 and 140 mm. Always follow the minimum insertion depth recommended by your bike frame manufacturer if it is greater than the number marked on your dropper post. Minimum insertion depth varies by travel length and is specified on the Specs and Dimensions page. The longest travel dropper post that will fit you and your bike can be determined using our dropper post length calculator tool. Spacers can be installed to reduce the travel of the dropper post. Custom built dropper posts can be purchased with spacers installed at the factory. Compatible with any ebike that uses a conventional dropper post mounting and actuating system.
