Familiarity: I've put it through the wringer
Coming up on my second winter with this post and not looking forward to it. The plunger is wholly NOT ergonomically correct and cannot be made better by adjusting the position of it. Yeah, I feel bad having to shell-out another Hundred bucks for the lever that it should have come with; but, on longer rides when your hands begin to cramp, that plunger just continues to get worse and worse. That said, it works great on shorter rides (under 2 hours) in the heat of summer! And I like the way it snaps / clicks when it tops out, letting you know that it has returned to the full-up position. In the winter however, when your hands get fatigued and cold, forget it! Because the hydraulic oil gets more viscus as the mercury drops, that plunger gets even harder to actuate. So, I bought the lever.
The post comes with 5 weight oil which was a disaster last winter. I live in Texas, so I have enjoyed riding year round, only last winter was my first with this post. We all know that the temperature drops as we climb and somewhere around 45 degrees F the post gets stuck in the down position, because the oil becomes too thick to move anymore. This even happened to me in Crested Butte, CO in July, when it rained at around 11,000 feet and the temps plummeted. I decided to do a total rebuild on the post, installing both 2.5 weight oil and the one-by, lever-style actuator. I will update this after I have given it the proper amount of testing / riding in a variety of temperatures and altitudes. Fingers-crossed!
