Presta, 48mm valve My OTHER similarly priced carbon frame 1X11 fitness bike (made by the most popular USA brand) has a Shimano GRX groupset which I prefer, but I prefer the frame geometry on the Specialized for its ergonomics & lower center of gravity (I ride 1" lower to the ground on the Specialized, both frames being XL size) and the front handlebar shock isolation is also superior on the Specialized. I would recommend the Sirrus X Carbon 5.0, but believe the GRX groupset on my other other bike is better! ## Sirrus X 5.0
