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!
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.
