Looking for feedback on Trek Domane

[rnhood]

Well, "sway" may not be the best term. The seatpost actually deflects to the rear, so maybe deflect is the proper term. The Roubaix on the other hand, while having a small component of rearward deflection, has a greater component of vertical deflection (like a true shock absorber).

Both do a good job, although some may like one method better than the other.
