MTB Suspension Seat Post Review – XC Mountain Biking for Beginners

MTB Suspension Seat Post Review – XC Mountain Biking for Beginners


In this video we will be quickly cover the
suspension seat post options for hard tail XC mountain bike riders.
For clarification, this video will not cover dropper seat posts and not intended for racing,
riders of full suspension bikes, all mountain, endureo, or downhill.
Not all XC riders need or want a dropper post and there are plenty of dropper post compare
videos out there. I will also not review any of beach cruiser
linear suspension posts since they function at the wrong angle.
As with all other bike parts, weather, temperature and rider weight should also be taken into
account before purchasing. Currently, there are several seat posts that
are appropriate for cross country ridding that function at an appropriate angle.
Since weight is a big factor for XC riders, I decided to start with the heaviest seat
post and end with the lightest. At the top of our list: SR Suntour NCX SP12
This seat post uses a spring loaded piston inside the post.
It weighs 765 grams or 1.69 lbs and has 50mm of travel
And the price is typically about $125 This post is recommended for riders that don�t
want the un dampened spring bounce that occurs with other posts.
The bottom of the post has an adjustment for the preload.
The biggest complaint about this post is it can wear against the saddle rails.
Also, the rail clamps from the sides, instead of the top and bottom.
Therefore, if you have carbon or other 7×9 rails, they will not fit properly.
It is possible there may be a 7×9 adapter for this post, but I have not found one.
So, the dampened shock is good, but the rail rubbing is not a good sign.
With all that said, it is important to note this post is top heavy.
As a beginner XC rider, when you gain confidence and speed, the top weight starts becoming
a hassle when making tight quick turns. The safe angle of the bike in turns is much
tighter and you run a higher risk of a washout or overshooting a turn. Next up The Cane Creek Thusbuster LT
This seat post has become the recommended standard in suspension seat posts for casual
XC riders it weighs 495 grams or 1.3 lbs and has a huge
75mm of travel It is available in various sizes and lengths,
accommodates various rider weights with an included set of insert elastomers.
The build quality is excellent as well. I rode my thudbuster LT for four years, and
it still looks and rides like the day I got it.
It can also get bouncy in rough terrain if you do not get off your saddle much.
Also, the extended amount of travel can be a concern.
At a going price of $130, it is a reliable post and great for beginners and riders concerned
about their back side. But, it is still very top heavy. Next on the list is The Tamer Pivot Plus XC
This suspension seat post also has a spring piston like the suntour.
Its weight is just 460 grams or 1.01 pounds and has 65mm of travel
Like the thudbuster, it does not have dampening and can get bouncy.
However, it does have a preload adjustment like the suntour.
The price is just $115 and I consider it to be a slightly lower weight, lower quality
and price from the thudbuster. And we also have on the list the BodyFloat Bike Suspension Carbon Post
This post is rather new and there are not many long term reviews on it yet.
It weighs just 428 grams or 0.94 pounds and has 38mm of travel
It uses replaceable springs and also has no dampening.
The price is a whopping $395 and is the most expensive one available. And last is the honorable mention of the Niner RDO seat post
This seat post is just 220 grams or 0.46 lbs The price is $190, but the travel is just
8mm. (Less than 1 cm)
So it may take a tiny bite out of the ride, it is not intended for the casual middle aged
schmuck like me. So, what suspension seat post am I using now?
Well, like a true lab rat, I am trying something that may not be the best of ideas for an idiot
XC rider. I am testing out a knock-off seat post of
the canyon VCLS 2.0. I know the seat post is a knockoff because
I got the 31.6mm size, and the real canyon seat post is only available in 27.2mm.
With that said, it weighs just 225 grams or 0.5 lbs and cost me just $55.
Since it uses a side rail clamp, I had to special order a 7×9 flip head kit from Germany
for it to work with my carbon rail saddles. The total cost (with the 7×9 rail kit) was
$99. So far I love it. The combined total weight
of this post and my carbon saddle is just 365 grams or 0.8 lbs.
The travel is only 20mm, But, I have found that it is enough to ease
the ride and greatly reduce the top heaviness of my bike
Making it MUCH easier to turn quickly with less kissing the ground. How long will this knock-off saddle last on
the XC trails? I have no clue.
I have had to tighten it a couple times on the first few miles, but for now it is holding
very well. How long do you think the knock off seat post
will last? Let us know in the comments below.
Also, if you have a suspension seat post, tell us your model and experiences.
Thanks and have fun out there.
