The Over/Under Bicycle Bar End Plugs

You can say a lot with our Over/Under Bar End Plugs AND you can say it with 11 different unique typefaces. (Each one named after a famous cyclist BTW.) Don't forget to match it with one of our Over/Under Headset Caps and pick up some accessories to complete the look! PLEASE NOTE: Many of our typefaces are available in UPPERCASE only. No emojis please!

KustomCaps Bar End Plugs (BEPS) are designed to expand to fit the inner diameter of most bicycle handlebars.

We offer two sizes, Road and MTB. The outer discs on the Road BEPS measure .98” (25mm) and the MTB discs measure 1.25” (32mm) in diameter.

The internal expansion plugs are the same size for both. They start at 16.2mm in diameter but can expand up to 24.4mm when fully tightened.

As their names suggest, our Road BEPS work well with drop bars and our MTB BEPS are better for straight bars with grips.

A set of road BEPS weigh 32 grams and a set of MTB BEPS weigh 36 grams.

The price is for ONE PAIR (2) bar end plugs.
