Joseph ★★★★★

Finally, an adapter that lets me use my eitech bars with standard inch-spaced accessories—the 12.7 mm holes are a perfect fit. It’s solid and does exactly what it’s supposed to without any fuss.

Kevin H. ★★★★★

Was pleasantly surprised this actually fits perfectly, the 10mm and 12.7mm hole spacing let me finally connect my eitech bars to a different brand's stem without any wobble.

Leo ★★★★★

I've been trying to combine different component sets and these adapter holes—10mm and 12.7mm—fit perfectly, making my builds finally work. The conversion from cm to inches is spot on, which saved me from buying all new parts.
