Stem compatibility

The fork is compatible with all current Brompton stems.


The Vostok Fork has IS disk mounts and a Brompton caliper brake mount. The disk brake rotor's recommended diameter is 160 mm, but larger rotors will fit. Install either a mechanical or a hydraulic brake. Use an appropriate Post Mount adaptor if needed.


Standard fork catcher, reflector etc will fit the fork, as well as the mudguard. The mudguard stay has to be modified, please see an appropriate article in the Documentation section.
