TECHNICAL SERVICE BULLETIN #158 - VARIO SEATPOST TRAVEL ADJUST UPDATE

THIS TECHNICAL SERVICE BULLETIN IS INTENDED FOR: 

e*thirteen distributors, dealers & end-users

PRODUCT INCLUDED

e*thirteen Vario Seatpost - All lengths and sizes  

BACKGROUND

e*thirteen Vario droppers were released in 2020 and used a stepped bushing to allow tool free travel changes by simply rotating the bushing. 

Around the time the Vario was released, e*thirteen learned of a patent filed  in Taiwan which detailed a similar method of  achieving travel adjustment in a  seatpost. That application was subsequently granted, so out of respect for that parties invention e*thirteen is changing the method used to achieve travel adjustments of the Vario seatposts. 

RESOLUTION

Beginning in November 2021, Vario Seatposts began shipping with an updated travel adjust bushing assembly which replaces the original stepped assembly. The new assembly consists of a main bushing and a stack of 5mm shims which allow for the same level of adjustability as the original bushing simply by adding or removing shims. This process continues to be a tool-free operation and has no impact on Vario product specifications beyond the slight procedural change for adjusting the travel. 

The adjustable travel bushing will continue to be supplied in our Vario Seatpost Refresh kit and can be purchased as a service item in service item: SPS20-103 - e*thirteen | Vario Infinite Dropper Rebuild Kit | Incl. Collar, Seal, Adjustable Travel Bushing, Keys, Lower Bushing | Fits All Vario Posts

Owners manuals and technical support documents will be updated to show both travel adjust options.
