Summary
The Specialized Roubaix is celebrated for its endurance-focused design, offering a smoother ride on rough roads thanks to Zertz inserts and carbon layup, alongside a sharper, more focused ride feel. It maintains comfort with a stiffer frame and additional compliance from the Cobl Gobl-R seatpost, aiming for uniform performance across the range. The bike is also noted for its considerable stiffness and lighter frame weight compared to previous iterations.

The slighter longer wheelbase and the frame's vertical compliance allow the rider to ease up on the brakes and let the bike carve its way down the hill.

Specialized is on a roll with its sponsored athletes and not-yet-released bikes. Christoph Sauser just won the world mountain bike championships on a new Epic, which will be formally introduced next week and available later this year. But the bike that’s here now is the Roubaix SL2, the bike Tom Boonen won Paris-Roubaix on this spring, well before it was available for sale.
