> Wheel reflectors are also pretty useless

Never understood that. More visibility = potentially slightly less likely to get hit by a distracted driver so why remove the shiny reflectors spinning on your wheels?

And what’s a 20g saving per wheel when we carry so much more extra weight on our bodies.

Weight on the outside of a wheel matters more than weight on the rest of the bike for racing types - it increases the rotational inertia of the wheel, slowing acceleration & braking on top of any actual weight increase.

Personally I just buy tyres with reflective tape on the sidewalls. These are mandatory in some EU countries & are pretty effective in my experience.

Doesn't the reflective tape weight just about same? :)

The weight comment was facetious (obviously, I thought). That said, some cyclists might actually consider it seriously.
