The carbon Service Course SL seatpost is specifically tuned to be more shock absorbing than the “comfort” seatposts on the market. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you’ll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt head accessibility. With 0mm and 20mm setback options, it’s possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types.

Just perfect ítems ! Very honest!
from the color to the style and the fit! Perfect!
The S-Works Prevail 3 is one of the most comfortable bike helmets I’ve worn. The fit system adjusts perfectly, and once I ratchet the MIPS cradle to my head, the helmet almost disappears — it conforms so well that I barely notice I’m wearing it.
Ventilation is excellent. Riding in moderate weather around the mid-70s, my head stayed cool and comfortable without overheating. The airflow design really works.
Thankfully, I haven’t had to test the helmet in a crash, and I hope I never do. But the build quality and design give me a lot of confidence in the protection it offers. Highly recommended.
Very impressed by the whole experience with Sierra Bicycle Supply! The frameset was just as shown - brand new and gorgeous. It shipped fast with tracking info. Great pricing on the frameset and I picked up other stuff for my build. Great overall experience - highly recommended!!
Amazing bike at super price. Free shipping. Highly recommend buying from these guys.
Smooth, fast, and honestly impressive service in this day and age. Thanks Sierra, ya’ll rock!
True to size, comfortable, sticky. Confidence inspiring.
I'm satisfied with my purchase and my new bike tires I have saved money by choosing Sierra bicycle supply
Great product!
Such a great saddle! I like this more than my older 3D Specialized saddle, as the nose of this one is a little broader at the front. This sort of gives to really comfortable positions, one when I am riding the hoods and the other down in the bars. Highly recommended!
