2×11 is absolutely still a solid choice for road riding. While 12-speed has become the current standard on new performance bikes, 11-speed drivetrains shift crisply, offer plenty of gear range for most terrain, and are very reliable. The main difference is that 12-speed gives you slightly smaller jumps between gears, which helps you maintain a comfortable pedaling rhythm (cadence) — but for most riders, that difference is subtle.
Where 2×11 really shines is value. You'll often find it on mid-range bikes and closeout models at significantly lower prices than comparable 12-speed setups. Replacement cassettes, chains, and other wear parts also tend to cost less for 11-speed systems.
If you're shopping on a budget or find a great deal on a bike with 2×11, don't hesitate. It's a proven, capable system that will serve you well for years. The one thing to check is the cassette range — make sure it offers low enough gears for the climbing you plan to do, since that matters more than the total number of gears.
