Description

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.

Features
  • Runs spline or bolt-on. A removable adapter insert lets the one sprocket suit 19mm and 22mm spline drive, or 19mm, 22mm and 24mm bolt-on cranks.
  • Guard is built in. The guard runs as part of the sprocket, keeping your chain and teeth protected without adding a separate bolt-on plate.
  • CNC machined 6061 aluminium. Machined from 6061 aluminium and made in the USA, so it is built to take hits and keep the chain running smooth.
  • 25T or 28T. Two tooth counts to set your gearing, both cut for 1/8 inch chain.
  • Black or silver anodised. Anodised finish with laser etched graphics, and 125g on the scales in 25T without the insert.
