Rase adjustable seatpost
The Rase Rapid Adjustable seatpost features 9 inches of seatpost lowering travel. It retails for $400 and weighs about 500 grams without the lever.
So I talked to the friendly folks at Rase and rode around in their test bikes. It’s an interesting concept.
Pros:
- up to 9 inches of drop adjustability and that can be adjusted to anything less than that.
- the machining and construction seem very good
- the seat clamps are beefy and well designed.
Cons:
- the price is $400 and is above established competitors
- weight is 500 grams (without lever)
- 9 inches of adjustable travel is not needed by most riders for trail riding
- dirt and contamination can be a big issue. There seems to be a bunch of areas where dirt and water can collect and maybe get in the frame
- the up and down action is not very smooth when sitting near the rear of the saddle. Also, there ’s always a big click when the pin falls into one of the adjustment holes
- the mini ‘brake’ lever used to activate the saddle is not appropriate for most high end bikes. Hopefully, an alternate lever will become available.

$400! And an extra brake lever on my bars?! I’ll stick with the gravity dropper, thanks.

Hey,
My husband and I stopped by the RASE booth and chatted with the RASE developer for a while. He was real cool and took time to explain how this product works.
I tested RASE out and all I could think about was FINALLY I don’t have to get off and adjust my seat before a fly down Slickrock!

I have talked to the People at Rase and they are working on making it smoother and the lever is going to be smaller.
It will be really competitive from what i am hearing. Light. Smooth, more adjustable than anything in its class.
Here are some of the features I have noticed that are no available on the other posts.
It has an offset. That is something I really like. I race with a lay back seat post . I thought I woulod never find a post that was quickly adjustable and has a lay back off set. When racing some of the DH here is Ca it helps to be able to pop your seat up a little in places. It is a big plus in Super D racing.
It also come is a 31.6 so it can work on the larger seat tubes. The GD does not . They told me to buy shims.
I told them that sound like a band aid fix to a simple problem and I’m not into it. I sold the GD.
To put shims in the seat tube of a $2800.00 frame just seems silly. So I went back to my Thomson layback.
A feature that this post has over the speed ball is it is a more positive locking set post meaning it will not pull up and out when you go off a jump and squeeze with your legs like the speed ball.
Me being a Moto X racer I use my legs a lot to hold on to the seat.
When the seat pops up 4 inches that would alow the bike to drop . That is no good for me. I tried it . I hated it.
I sold it . It did come in a 31.6
I cant wait to try the new Rase seat post. It sound like it has everything I am looking for.
