SHUTTLE AM DROPPER POST FIT GUIDE
Seatpost range:
The Shuttle AM features a low stand-over height and short seat tubes to allow
the use of longer travel dropper posts and/or more flexibility for a wider
range of rider sizes.
There are some limitations that each dropper post can accommodate for each
frame size based on the individual rider’s saddle height, so it is important
to check fit before choosing the travel and model of dropper post for your
Shuttle AM.
Find your saddle height:
- On a current bike with the seat at max height (basically your XC saddle height), measure from the center of the crank spindle to the rails of the saddle (the “X” measurement in the illustration in Fig. 3) This measurement is taken to the rails of the saddle instead of the top of the seat because variances in saddle thickness can affect the measurement. Choose your Shuttle AM frame size.
- Based on your frame size selection, you can review the chart below to select the longest travel post that you are able to run. Your saddle height needs to fall in between the “Minimum” and “Maximum” saddle height measurements listed on the chart. For instance, if you want to run a 175mm FOX Transfer post on a medium Shuttle AM and your saddle height falls below 60.6 cm (23.8”) then you need to order the 150mm post instead. Or if your saddle height is over 76.7 cm (30.2”) then you need at least a 175mm post.
- If you are close to or at the lowest saddle height for your chosen dropper you will want to check for clearance between the rear tire at full suspension travel and the back of the seat with the dropper at its lowest position. Do this by compressing your dropper post to the bottom of its travel, then let the air out of the shock and compress the bike to confirm the tire does not contact the saddle.
*This is particularly important for Smaller frames.
