Give yourself some extra cush with Avenir's Multi-Fit Suspension Seatpost. It provides 1.75 inches of travel via a spring and elastomer system. It's perfect for hardtail mountain bikes, your commuter or comfort/hybrid bikes. Its full aluminum construction makes it light and durable, and the anti-rotation square slider and 1-bolt micro-adjust head make it user friendly. With the included shims, your post will fit 25.4-28mm seat tubes, too.
