FSA updates K-Force electronic groupset to be 12-speed and disc brake-only

Semi-wireless system gets an upgrade, but rim brakes are out

FSA has announced a new version of its K-Force groupset that’s 12-speed, coming into line with the top-end groupsets from Shimano, SRAM, and Campagnolo. FSA has also binned the rim brakes of the previous incarnation, making the groupset disc brake-only.

We reviewed the original FSA K-Force groupset back in 2018 and said it was a welcome addition to the market but not as smooth in operation as the likes of Shimano Di2 or SRAM eTap.

Check out our review of the previous generation FSA K-Force WE groupset 

The new FSA K-Force groupset is similar in that you get a set of standalone shifters that communicate with the control unit mounted on the front derailleur via ANT+. From here on in, things are controlled via wires from the internal battery for power to the derailleurs, and for the front and rear derailleurs to talk to each other.

The shifters are powered by coin cells while the battery for the rear section of the groupset is rechargeable.

Shimano’s latest Dura-Ace and Ultegra Di2 groupsets are each similar in that they’re semi-wireless – the shifters aren’t wired to the rest of the system – although the communication goes via the rear derailleur.

It’s no surprise that FSA has moved to 12-speed to come onto level terms with all of its key rivals, nor is it any surprise that it has dropped rim brakes, the market being hugely disc brake orientated at the upper level.

Although the cassette picture clearly shows a 12spd stamp, it only has 11 cogs...

The interesting question for 99% of people is, will the cassette, cranks or chain work with sram, or shimano?
