PROFILE Signet Universal Sprocket w/ Guard
The Profile Signet Guard Sprocket is a clean, bomb-proof option for riders who want strength, compatibility, and classic Profile quality.
CNC-machined from 6061 aluminium and made in the USA, this guard sprocket is built to take hits while keeping your chain running smooth and protected.
Its universal design is the real standout — using a removable adapter insert, the Signet Guard can run spline drive or bolt-on, making it compatible with pretty much any modern crank setup. One sprocket, multiple crank standards, zero fuss.
Add an adapter at checkout (recommended), grab one separately, or run your existing insert if you already have one dialled.
