Double Bass Question for Xeros bass wheel users

[BudD]

Does the Xeros bass wheel have two flats ground into the shaft to keep the wheel oriented relative to the body of the bass? I emailed Xeros several weeks ago, but they never replied. There's no mention of it in any of the product descriptions and I can't tell by looking at photos.

Looks like I'm stuck buying it or the much more expensive Gaines wheel -- they're the only ones offering wheels with a 12mm shaft.

Mine has one flat. As long as the screw is tight, I haven't had a problem with it turning - even when walking close to a mile at a time.

One in mine also. No problem in 3 yrs of use.

Thanks for quick responses. I'll go with the Xeros.

Does anyone know where to get just a Xeros wheel shaft? I just changed endpins and forgot that the new one is a different diameter. Thanks.
