"FSA presents its first drivetrain: after years of study and development, K-Force WE is ready to ride. K-Force WE is a high-tech electronic groupset with an elegant design. A unique product that will make you change the way you ride your bike. Long battery life, different size levers, and wireless technology at the shifters for smooth, quiet and precise shifting." - FSA

FSA K-Force WE is a 2x semi-wireless drivetrain, meaning the hydraulic brake / shift levers are powered individually by a CR2032 coin cell battery and communicate wirelessly with the derailleurs. The front and rear derailleurs are connected directly by wire to the internal battery, which typically resides within the bike's seatpost. The advantage of FSA's WE system is longer than usual battery life than what is normally associated with wireless components.

It is important to note that FSA K-Force WE was never designed for the rigors of gravel cycling, road cycling was its original intended market. For this reason alone, we'd like to thank FSA…
