Will TM84SR Work On Mountain Bike's Dropper Seat Post

Question:
Hi, Will these work for high pressure? Id like to add them to my per seatpost on my mountain bike. I typically run 150-200 psi on the per post.

Hey Anthony!
Yes, these will work, but I don't recommend them for you. The maximum PSI rating on this extender is 220 PSI and it extends two inches so if that works for your setup, TireMinder 135 Degree Valve Extender - Qty 2 # TM84SR may work for your mountain bike's dropper seat post. The extender is designed for vehicle use so while it may fit on a standard Schrader valve on your bike, I would not recommend it to be used in this scenario.
Are you looking to just extend the valve on the seat post or is there something specific you're looking to achieve?
