NCX Seatpost Spring

received this item along with the seat post in a very timely manner from time of my ordering them. The red tension spring was not difficult to exchange with the original manufacturers spring. And I have enjoyed the comfort this has provided me in my extended rides of 20-25 miles. Wished I would have ordered it sooner.

Optional seatpost springs cover a large range of people. They are awesome.

Spring is excellent but would prefer it was included in order (stiffer spring) instead of extra add on

The Suntour people have the weight ranges dialed in - the stock spring was just a little too light for me, as they predicted, so I purchased the heavy spring and it works exactly like it should.

I bought the Blue spring as I needed a little softer action in the seat post.
This spring provided just the right amount of spring action needed,
quite a difference as compared to the stock spring.
This was is a good option on reducing the harshness of the seat post suspension, I rate this spring at a 5 star.
