Zipp service course SL seatpost

Strong, yet light as a whisper, Zipp's Service Course SL is everything you could want in a seatpost. Forged out of a single piece of tough 7075 aluminum, a low-profile clamp allows you to slide the saddle extra far back on the rails, giving you more room to optimize your position. The clamp even features downward-facing bolts for micro-adjustments to achieve that perfect fit.
