NCX Seatpost Spring

I am loving my new suspension seat post with the red spring, bumps on the road seem to disappear! I was near the top of the weight limit with the blue spring and didn't want to bottom out. I'm so glad I did, no more sore bum after riding!

A very big positive difference with this spring.

Spring is really hard,I don't see any difference with middle model, looks like same spring different color

OVERALL VERY SATISFIED WITH PRODUCT. I LIKE TO ADD THAT ADDITIONAL INSTRUCTIONS SHOULD BE INCLUDED WHEN UPGRADING FROM THE STOCK SPRING. IE: REMOVE/UN-THREAD BLACK KNUCKLE FROM STOCK SPRING AND THREAD ON TO NEW SPRING., ONCE YOU HAVE REMOVED THE BLUE OR RED MIDDLE BIT. BE SURE ADD SOME LIGHT GREASE TO SPRING

We had to replace the default spring for men, with a red soft spring for my wife. After this change, its fantastic.
