Support without the weight.

If there's one thing that Zipp excels at, it's taking a good idea and rolling with it. Take Firecrest for example. In a matter of a few years, it's extended itself to every iteration of Zipp carbon wheels -- and for good reason, too. The same principle applies, here, with the SL Speed Seatpost. With an overall weight that's 35 grams lighter than the Service Course Seatpost, the top-of-the-line SL Speed shares the same highly-adjustable and low-profile clamp system as the Service Course, only opting for a carbon fiber construction instead of aluminum. This means that the Speed SL's not only lighter, but it'll also provide enhanced ride characteristics.

Zipp's carbon mastery allowed it to chisel the Speed SL's weight securely under 190g. Impressively, though, this reduction was also coupled with an enhancement to strength, resulting in a post durable enough for use in races, like Roubaix, that explore component limits. In fact, the Speed SL's strength warrants a 300lb rider weight limit -- the same as Zipp's alloy posts. Also shared with those posts, as mentioned above, is the clamping system.

Zipp's theory on saddle position is to provide as much adjustment as possible. And by paying close attention to the clamp assembly, Zipp's engineers have designed a two-bolt system with both extended range and angle adjustment. This allows you to find a position that permits the most power and comfort, and once adjusted, the titanium, two-bolt assembly is ensured to not slip out of place.

The lower portion of the clamp is designed to be a bit longer than what you see on other seatposts. Essentially, this is to support the saddle rails for those of you who prefer a rearward position. And in this day of ultralight titanium and carbon rails, the extra support and insurance against rail damage is a definite improvement.

The Zipp SL Speed Seatpost is available in a 330 length and in both 27.2 and 31.6mm diameters. Additionally, each length and diameter option is available in either a 0 or 20mm offset.

Excellent but $$$$

  • Familiarity: I've used it several times

Performance and quality is definitely 5 stars. Even lighter and more compliant than the aluminum SL seatpost, but same great clamp design. At almost $300, it is the most expensive seatpost I have ever purchased. The color/graphics options are limited too - I'd like to see a stealth option to blend better with the SL components. The white graphic sticks out so make sure it fits your scheme. (Photo 27.2 x 0)

Works like a charm

    A pricey carbon tube :) but it is super light and works fabulously on my bike !!!

    • Familiarity: I've put it through the wringer

    This is hands down the best seatpost I have ever used. Setup is simple, I don't notice any flex (i'm 165lbs) but there is plenty of vibration dampening for the chip seal roads we have here in SE Idaho. Plus, it looks beautiful.

    Excellent seat post

    Hands down, the best seatpost so far :) Has a large clamp area, very strong and secure at the mount. Switched from a Ritchey Superlogic - which the clamp area was not user friendly to set up. This seatpost was dead on out of the box, seems to soak up the bumps that much better (due to the robust design) weighed in at 198gm for the 27.2mm. If you can afford it - best seatpost there is :) Also comes with a hex wrench extension (that can tighten at an angle), so you can easily get up into the seatpost to clamp it correctly - nice touch. Also includes two caps for the top of the seatpost, one is white (in my picture) and there is also a red one - just clips right on, change your frame color? just snap the other on :)
