Product Review: FSA K-Force Seatpost SB25

Hi guys! It’s time to share the word on one of my favorite sponsors FSA! While being at home I had the chance to look over what I have on my hands this year and this time I’m going to share my experience with two particular FSA products. But first let me talk you about the brand: FSA is known for being a world class company with cycling components for the road and mountain bike.

Besides working closely with the best athletes in the world, they also work with expertise with constant feedback to develop the next range of products. Combining passion and commitment to innovative design, research and development, materials and manufacturing processes, FSA ensures they deliver technically superior components that deliver the ultimate performance that riders demand, and all at competitive prices.

FSA K-Force Seatpost SB25 Review

The FSA K-Force carbon SB25 seatpost is awesome. While riding on bumpy roads I can feel how the FSA K-Force carbon SB25 seatpost absorbs most of the vibrations making my long rides more comfortable for my lower back and my entire body. The light weight just adds more benefits to the seatpost and to be honest, it looks so good with my 2021 Bottecchia Emme 4 bike.

FSA has changed the graphics to make the K-Force Seatpost SB25 look really clean for 2020. The one piece continuous hi modulus carbon fiber shaft allows for a light weight design and minimal top clamps allow for a sleek looking seatpost that comes in at 204 grams for a 27.2 diameter and 350 mm length.

The FSA K-Force Seatpost allows for a battery mount for the FSA WE groupset and Shimano Di2 groupset at the bottom of the seatpost.
