Specialized’sWU post has a unique saddletipping action that some riders might like but it has a lot of downsides, including cost,weight, height, rattle and only a single fit option. The big “wooo!” with theWU is that, while the main shaft only drops 115mm, a secondary shaft inside drops another centimetre, tipping the back of the saddle down by another 35mm.This is designed to give support under braking and extra thigh control on steep/fast descents, and some of our testers liked it. Because the nose doesn’t lower, Spesh’s “effective 150mm drop” claim is stretching it, though, and theWU mechanism adds extra height under the saddle. The head soon starts to wobble and rattle on the shaft too, which isn’t helped by the savage return speed and slamming top-out even on its slowest setting. It’s also heavy, expensive and only comes in a 34.9mm diameter, making the simple but effective $375 Command Post IRcc our recommended Spesh dropper.
