The aluminium bikes available this year are better than they ever have been. After some key models saw reductions in weight this year, it's meant that what used to be the downside to aluminium is no longer all that bad. We have rounded up the aluminium road bikes which we think are the best options in 2024. They span all price points, spec levels, brands and riding styles. We have bikes from Specialized, Cannondale, Trek, Canyon and Triban. Which would you pick?
