Is a spacer needed for the drive-side when installing a bottom bracket kickstand on the NDS? I saw this kickstand on eBay:



It mounts on the bottom bracket. When installing this, should a spacer also be installed on the other side of the bottom bracket?

Right now, my crankset is a Shimano 105 FC-5700 with the inner chainring removed and my cassette is a 10-speed 105 11-28T. I was just wondering if a spacer would be added to the drive side, would that affect the chainline much?
These are intended to clamp around the cup itself.

Spindles have essentially zero spline engagement to lose. You can't really put spacers under road outboard BB cups.
