Syntace P6 Carbon HiFlex
Syntace's P6 Carbon HiFlex is not a shock absorbing seatpost. It is a carbon seatpost that is designed to gently dampen the effects of rough roads or rutted trails, which, in turn, lets you focus on using your legs to put power to the pedals. For the P6, Syntace arranged carbon fibers in such a manner that the seatpost is able to flex backwards under load, which increases a rider's comfort without any sideways movement. The benefit is that the post takes the edge off of the bumps on your road bike. If you're on your mountain bike, conventional seatposts and saddles force you to lift your weight slightly from the perch to minimize bumps. This means you're hovering instead of standing or sitting, which is a tiring position to ride in. Using the P6 HiFlex, however, you're able to remain seated over ruts in the trail, letting your legs push the pedals rather than holding you off the saddle. The HiFlex also features an integrated carbon head. It uses cold-forged alloy (7075) lower rail plates and deep-head titanium bolts to give 30 degrees of saddle tilt, plus maximum rail support. The Syntace P6 Carbon HiFlex is available in the sizes 27. 2/400mm, 30. 9/300mm, 30. 9/400mm, 31. 6/300mm, 31. 6/400mm, and 34. 9/480mm.
