From the web:

Authentic Floyd Rose-locking trem performance comes to your SG-, Flying V-, or LP-style electric in the top-loading Floyd Rose FRX — with no routing required! Just install two small wood screws in your headstock for the included locking nut, and some qualified setup work is all that stands between you and the axe of your dreams. The bridge itself installs directly into your existing stopbar posts, eliminating the need to rout out a cavity for the block or springs. Intonation, spring tension, height, and all other adjustments are performed directly from the top of the Floyd Rose FRX. Best of all, the FRX is completely reversible (save for the nut screw holes), so there's low risk of injuring your prized instrument. An included Tremstable ball post allows users to engage full float mode at the cost of some tuning stability or assisted float to bring the bridge back up to a stable tuned position after engaging. Take it from guitarists at Sweetwater: if you're looking to get true Floyd Rose performance out of your Gibson SG, Les Paul, or Flying V without performing major surgery, the Floyd Rose FRX is hands down the way to go.
