As first built in winter guise with fenders Carbon fiber endurance road bike with 2x12 SRAM Force AXS One of the things about getting to ride a bunch of very different bikes of different eras is you start to get an idea of what improvements have evolved over the years. In particular, the idea that a ' road bike ' doesn't have to be a ' race bike ' to still be sporty. This is where the current idea of an ' endurance bike' comes in. It is a bike that is designed to be nimble, light and fast, while having a slightly more upright and comfort-oriented position. Oh, and in the 2020s, accept wider tires. Wait, wide tires? Aren't they slow? Well... it turns out not so much. A bit wider, run at correspondingly lower pressures, they ride both more comfortably and actually faster in the real world (where roads are not smooth and hysteresis takes away energy). So a nimble, fast setup that is also comfortable on long rides. Winner concept. And not in my inventor
