A significant deterrent to everyday bike riding is the prospect of getting chain grease on your clothing. European city bikes generally solve this problem with internal hub gears and partial or full or chainguards. The internal hub gearing also reduces the maintenance.
But here in the US, most bikes now have both front and rear derailleurs. And it’s just about impossible to find a chainguard that works in combination with derailleurs. But the new SKS Chainboard seems to be just that.
