Dynafit Radical FT Base Plate w/ Brakes -
You'll need to swap the entire Dynafit Radical FT Base Plate if you want to change the brake width on your Dynafit Radical FT bindings. The procedure involves loosening the lateral heel adjustment screw cap completely and removing it, pulling out the internal springs and bushing, and taking the heel unit off the pivot post. You can then unscrew the old base plate and brake assembly and replace it with the new one, reassemble the heel, and readjust the release value spring. Be careful replacing the alloy end caps as they strip easily. Sound complicated? Bring it in to a qualified Dynafit dealer and have them do it for you.
The Radical FT Baseplate w/ 130mm Brakes by Dynafit is a heel base binding accessory.
