Why We Like The Highline XC/Gravel Dropper Seatpost

Crank Brothers are expanding their Highline series with the addition of the Highline XC/Gravel Dropper Seatpost to manage steep terrain and fast descents with greater control. The Highline XC/Gravel is equipped with a hydraulic IFP cartridge for smooth actuation and durability, and the two-bolt aluminum head fits most standard bikes with a diameter of 27.2 millimeters. Jagwire's premium cables and housing are included to ensure your dropper post is ready to hit the trail after easy installation.

Metal Fatigue

I've used it several times

The post function well, but the inner post or the top piece looks like it has metal fatigue. I am scared it may break

Was great- at first.

I've used it once or twice and have initial impressions

I was very excited to get this dropper, it appeared to be the best one for a 27.2 seat tube. It worked great for a couple weeks, and now is getting stuck at the halfway point (no crashes involved). Will have to do some furniture investigation.
