The Nerds are finally back with another group show! This week, one of the things we’re discussing is one of the hottest trends in gravel bikes: adjustable frame geometry.

Is it a way to really make bikes better, or is it just a way bike brands can hedge their bets? And what happens if it’s done poorly? As always, we have opinions.
