Colored collars are cosmetic swap parts, not size adapters. Learn how they fit Quad Lock stem and bar mounts, which colors exist, and when to replace one.
Quick answer
Colored collars are cosmetic replacement parts for your existing Quad Lock stem or bar mount. They change the look of the mount, not its fit, so choose a color rather than a size.
What a collar actually does on a stem or bar mount
The collar is the visible ring that sits on the outside of the mount body. It is a trim piece, so swapping it does not change how the mount clamps to your stem or bar. If your mount already fits your bike, a new collar will not make it fit a different bar diameter or stem cap.
That distinction matters when you shop: colored collars are listed by color, not by size. Treat them as handlebar mount accessories for appearance, and look to the mount model itself for fit questions.
Why there is no collar size chart
Quad Lock does not publish a collar size chart because the collar is matched to the mount it ships with, not to your handlebar. The catalog lists color options only, so any advice about numbered collar sizes would be guesswork.
If you are unsure whether a collar is compatible with your mount, check the mount model and generation first. The collar alone will not tell you whether the base mount fits your bike.
When replacing a collar is worth it
Swap a collar when you want a different accent color, when the original is scuffed or faded, or when you are refreshing a used mount. It is a low-cost way to change the look without buying a whole new mount.
Do not replace a collar to fix a loose or rattling mount. That points to the mount body or installation, and a new collar will not solve it.
Colored collar questions answered
- Do colored collars change the fit of my mount?
- No. The collar is a cosmetic trim piece. Fit is determined by the mount body and how it attaches to your stem or bar, so a new collar will not make a loose mount tight or a tight mount loose.
- What colors are available?
- The Quad Lock Stem Mount colored collars come in Black, White, and Red. Choose the one that matches your frame, contrasts with it, or replaces a worn original.
- How do I know which collar fits my mount?
- Match the collar to your mount model rather than measuring your handlebar. The collar is made for the mount it is listed with, and the product page lists color options only, not sizes. If your mount model is unclear, identify it before ordering a collar.
- Can I use a colored collar on a bar mount as well as a stem mount?
- The catalog lists colored collars for the Quad Lock Stem Mount. Bar mount compatibility is not stated in the supplied product information, so check your specific bar mount model before assuming a stem mount collar will fit.
- When should I replace a collar?
- Replace it when the color has faded, the surface is scratched, or you simply want a different look. Do not replace it to cure rattles or poor clamping, which are installation or mount-body issues.
