Description
Zipp Service Course Seatpost — Stiff and Light
The Zipp Service Course Seatpost is lightweight and strong for security and designed to offer a precise fit at an accessible price.
This aluminum seat post provides easy tool access to the downward facing bolt for easy setup and micro adjustments after it's mounted. Better fit means better performance to make you faster. An out-of-position saddle means wasted energy with every pedal stroke.
The secure, low-profile clamp allows the saddle to slide farther back along the rails, and with 0 mm and 20 mm setback options, it's possible for nearly any rider to achieve the perfect fit.
For high strength, low weight, and efficient use of every gram, the shaft and head are not bonded but are 3D-forged from 6061 aluminum. The Service Course Seatpost is 350 mm in length. Available in 27.2 or 31.6mm diameters and fits all common saddle rail types.

Reviews
2-bolt posts are the ONLY way to go if you want to adjust your saddle's tilt exactly! As for this one, it goes nicely with my TI frame (and silver stem), despite not being an exact match. I'm not crazy about the placement of one of the bolts (inside the post clamp), which is difficult to access. And I'm concerned about durability: an allen wrench fits in rather loosely, as if the bolt is already stripped. (Especially since I'm always messing with my bike fit.)
Not much to this review other than the seatpost is exactly as described and shown in the listing. Zipp makes a quality product and the silver looks good in a world that loves black cockpits.
I should've looked closer when I bought it, but if you're looking at the zero setback post, I'd look elsewhere. The Zipp post is solid and I had no trouble with it (the clamp in particular is easy to adjust and set) but I swapped saddles and ran out of forward space. I switched to the Easton EA70, which is straighter and has a similarly elegant clamp.
