Dropper Post Service
If you are a mountain biker, mud and dust are a part of the game. It doesn’t matter how regularly you wash your bike; dirt gets into just about everything.
To prolong your dropper seat post's lifetime and to keep it running smoothly, a regular service is required.
Dropper post service includes full teardown and inspection, and complete rebuild
Dropper posts are one of the most useful upgrades on modern mountain bikes — but like any moving component, they require maintenance over time.
If your dropper post feels slow, won’t stay up, sinks under weight, or stops working altogether, our Dropper Post Service can restore smooth operation and reliability on the trail.
We service most major dropper post systems.
