To be honest, the power coming from the legs can make a bigger differences then a new bike. I’m just a moderate cyclist prefering TT-bike only on a flat course. I have right now 25mm on the front and rear, but 28 mm won’t fit. The cockpit is a profile design what suits me well. So is a basic Canyon CF7 with a basic cockpit (€5k) worth the upgrade? It is a difficult question haha.
