Your seatpost is something you shouldn't have to think about once you install it. The Ritchey WCS Alloy 2-Bolt Seatpost stays put, holds your saddle in place, and keeps you in your ideal riding position.

Strengths: Reasonably light weight
Weaknesses: Saddle tilts no matter how much the clamp bolts are tightened
Took my dually out for its first ride on trails that require no suspension at all, and the seat tilted back going through the first dip in the trail. Tried to tighten the seat clamp bolts with small allen wrenches and the same thing happened in the next dip. The saddle clamp and bolt design is worthless, as shown by ten of eleven reviews filed under the WCS tag. There are front-to-back grooves under the seatpost where a curved washer slides to adjust the seat angle. Why aren't these grooves across the seatpost to prevent slippage? Why aren't the washers grooved like on cheaper heavier Ritchey posts? Don't take a chance unless you only ride on the road.
