17-23 mm Slotted Handlebar End Plug Trio
This is a set of three bike handlebar end plugs joined by snap-off tabs. They fit bars with an inner diameter of 17–19, 19–21 or 21–23 mm, and the caps are 26, 28 and 30 mm across. Each plug has a 25 mm hollow shank split into four flexing fingers with barbed rings. That gives a snug push-in fit when an old or unusual bike has lost its end cap and you only need one plug.
Handlebar Accessory Extender Bar Clamp
A split clamp for a 31.8 mm handlebar that carries a second 22.2 mm accessory bar stub 55 mm out to the side, so lights, a GPS, a bell and a phone mount stop fighting for stem space. Closed by two M5 bolts with captured nuts, 99 x 44 x 55 mm, gusseted web under the stub.
