Velox Bar Plugs
Velox bar plugs: no more lost plugs and no more bruised knees. Soft black rubber. These are for road bars, not MTB size bars. Note that they don't work with VO bars without modification - the plugs are a bit too big. You can grind them down to make them fit, but it's a bit of a chore. Use them with Nitto, and others, though. Price is per pair.
Difficult to slip in and star washer fails to grip nut to hold in place to tighten.
Standard aluminum bars. Had to trim
