RockShox Reverb AXS seatpost
I know - these are a ridiculous price!
BUT, if you really, really want a new wireless RockShox Reverb AXS post, we can get them!
Size wise, they are available in 100mm, 125mm, 150mm and 170mm travel and come in 30.9mm, 31.6mm and 34.9mm diameters.
The prices will probably fluctuate a bit during the pandemic.
