Zipp is hardly a company that needs an introduction. Known for being tested amongst the toughest and fastest in the peloton, Zipp's legacy stands tall. Zipp is committed to helping riders achieve their potential by offer high-quality components with innovative design and manufacturing.
Zipp managed to shave off a few grams by revamping their Service Course SL Seatpost. Though it is lighter, the seatpost is stronger and offers a precise fit that stays within budget. The low-profile clamp allows the saddle to slide farther back on the rails allowing for each rider to have their perfect fit. The clamp design also has a downward-facing bold that ensures easy micro-adjustment of the saddle even when it is mounted. Constructed with 7075 aluminum, the Service Course SL is durable, stiff and guaranteed not to disappoint. Offered in high-polished black with silver laser-etched graphics or beyond black with anodized with black.
The Zipp Service Course SL Seatpost is a well made, solid product from Zipp. The tilt angle hash are helpful and reminiscent of a Thomson post, if not as finely delineated.
The only negative I would mention is the difficulty adjusting the screw located closest to the post. None of my drivers were able to adjust the screw without removing and reinserting the tool every half turn or so...and that includes wrenches with bit adapters that are too wide to fit in the inset where the adjustment screw is located. Otherwise I would give this seat post 5 stars.
Great seat post but Inner bolt difficult to adjust
Needed to get a more rigid seat post and went with this in the Beyond Black (looks great). I had reservations about the placement of the inner bolt, but purchased anyway. It's impossible to get at with a torque wrench or other bulky tool and finally settled on a standard allen wrench to tighten. If this bolt was easier to reach/tighten it would be a 5 star.
