P.4 Frame
Loading store availability...
Specialized
This totally redesigned P.Series frame gives riders of all sizes a jumping off point to a life on bikes. The lightweight, but tough alloy frame is designed to take all the hits and keep rolling—across all frame sizes. Our approach to these robust bikes centers around delivering a simple, high-quality platform that's versatile for all riders, and packs in category-first features that make a difference to the rider.
SLEEK SIMPLICITY — For the rider focusing on progression, eliminating every other variable is paramount. The durable lightweight alloy frame of the P.Series stands up to the tough demands of a modern DJ rig and accepts internally routed cables.
SIZED FOR ALL — Frames available in dedicated 20”; 24”; and 26” configurations as well as the P.4 that can run both 26” and 27.5” (P.4 is spec’d with 27.5”).
REIMAGINE YOUR RIDE — P.Series frames are dropper ready, derailleur compatible, and use adjustable dropouts.
TOUGH TECH — Boost spacing in the rear, a tapered headtube, and threaded bottom-bracket make P.Series stiff and easy to maintain.

Went with the rival setup instead of force and I am super happy that I did. If you don’t need the extra button on the hoods, these are probably the best value item in the AXS drivetrain.
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!
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.
