Carbon or aluminum road bike, which should I get?

Carbon is lighter, stiffer and smoother over long rides, which is why most performance and race riders choose it. Aluminium costs less and is tougher, and at the same price often comes with better components, making it a smart starting point. It comes down to your budget and how seriously you ride

What's the difference between a road bike and a gravel bike?

A road bike is built for speed and efficiency on sealed roads, with lighter frames, drop bars and narrow tyres. A gravel bike is more versatile, with wider tyres and a more relaxed position for handling loose surfaces and rougher terrain. If you're mostly on tarmac, a road bike is the go.
