Profile Design
The HSA 800 Evo Hydration System is an upgraded version of the HSF AERO HC 800, featuring improved Garmin placement, a refined rear cap mechanism, and a shape designed to minimize aero drag. It includes a flexible hose with a bite valve and magnetic retention, a direct/removable Garmin mount, a new mounting bracket with greater compatibility, and a high-retention cage. The HSF BTA cage offers a minimalist design for maximum versatility, with a low weight, high retention, and an integrated computer mount. The HSA 800 EVO bottle can also be replaced with a standard water bottle for shorter rides or races.

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!
The bike has lived up to all the hype! Flight Attendant frees up more brain bandwidth to focus on dropping my friends!
Nice gravel shoe. We got these for a Europe bike trip with lots of possible walking ( coffee shops , sightseeing). I have been breaking them in and like them so much that they will be my permanent gravel bike shoe. (Used my Mtb shoes before). Really like the room in toe and while not as stiff as my Mtb or road shoes, they are awesome for long rides.
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.
