PNW makes good stuff. I have a higher end post from them on my trail bike. The Cascade was easy to install, works smoothly and looks great. It’s a little heavy but I put it on my fatbike plus the cost is right so I can’t complain. The only reason I didn’t give it 5 stars is because it doesn’t come with a lever. That’s another $70.

Oh, and be aware the Loam lever only comes with a derailleur style cable but no housing. That was annoying as I had to go to the shop to purchase derailleur housing. Once installed it worked great.
