Honestly, this is bike is the bomb! The only thing that bothered me was the slow steering when compared to a normal Road bike. Of course, this is due to the increased tyre size, but what they lack in steering they make up for in comfort. This bike would be pretty great for a classic road race like the Paris-Roubaix. Overall, it is super agile and very comfortable, despite its aero geometry.
A short note on the tyres: they offer never-ending grip when its dry, but as soon as wet gravel comes into play, things get a little slippery. In reality, they are the Mario Cipollinis amongst balloon pneus. After riding the Exploro for two weeks I switched back to 22 mm Continental Sprinter tubulars, and I was a little afraid of cutting through the asphalt on such thin tyres.
In the end, if I could only own one bike, I would definitely go with the 3T Exploro with 650B wheels!
