    Prologo end plugs?

    just got a couple rolls of the Prologo bar tape. they have a new type of end plug that supposedly will not fall out. Looks like quite an engineered piece, however they came with no instructions and the Prologo site has nothing. How do these install? thanks!

    yes, those. when I google them, all I get are reviews on how nobody could figure out how to install them, but they are "innovative".

    Aren't they just a fancy twist lock? Turn them 90 degrees and the cam extends to hold them in?

    just got email reply from ribble. remove logo part of end plug to reveal allen bolt. tighten, then tap on the logo cap. works like a headset. would have taken awhile to uncover that! note to prologo: instructions would be nice.

    Expander bar plugs were very common back in the '60s. They were typically not rubber but a harder plastic like polyethylene. It appears that the main difference with the Prologo ones is that there is a cosmetic cover to the screw head.

    Kerry, you forgot about the grand daddy of plugs, the Velox all rubber plugs, which I believe are still made today.

    The hard plastic expanding plugs were generally a USA product, and were sized for 7/8" steel bars, while the Velox plugs are sized for the 24mm aluminum drop bars of the era.

    Solving any problem requires understanding the underlying cause

    I've still got Velox plugs on some of my bikes. They work great!
