I think more importantly, the endurance bikes run higher mechanical trail that is more suitable for the more upright body position, whereas the race bikes run lower trail figures, expecting more weight on the front wheel due to the lower/more forward body position. Even if you replicate the same position on the race bike, you’re likely forcing it outside the specs of how the bike was designed to be ridden.
For most people, endurance would be the better option…but people like buying what the pros use thinking there are marginal gains to be had.
