FSA K-Force and Afterburner disc brakes introduced

Cross-country and trail riding versions

FSA is poised to enter the mountain bike disc brake market early next year. The component manufacturer views disc brakes as a natural extension of its cockpit offerings, and plans to offer two models that fit into the company’s existing cross-country (K-Force) and trail (Afterburner) component groups. 

The K-Force brake will sell for US$369 per wheel, while the Afterburner brake will cost US$289. UK pricing is yet to be announced, and availability is expected to be early next year. Click through the image gallery, right, for detailed images of the two new discs.

Shared features include tool-free reach stroke/contact and reach adjust. The new brakes will come with front- and rear-specific hoses, presumably to balance modulation between the front and rear models. Both the K-Force and Afterburner will use mineral oil.

Claimed individual wheel weight for the K-Force is approximately 300g

To keep the weight in check, the top-end K-Force brake uses a carbon brake lever and titanium hardware. The more affordable Afterburner will come with an alloy brake lever and steel hardware.
