Specialized History and Information
Specialized Bicycle Components, commonly known as Specialized, was founded in 1974 by Mike Sinyard. Initially a component company, Sinyard sold his Volkswagen bus to fund a trip to Europe where he sourced high-quality Italian bicycle parts to sell in the United States. The company took a groundbreaking step in 1981 by introducing the Stumpjumper, the world's first mass-produced mountain bike. This iconic model made off-road cycling more accessible and changed the course of cycling history.
Specialized continued to innovate, venturing into manufacturing their own tires, road bikes, and later, e-bikes. Despite facing near bankruptcy in the 1990s, the company bounced back through continuous innovation. Today, Specialized is a global brand, employing almost 2,000 people worldwide and generating several hundred million euros in revenue.
What sets Specialized apart is its commitment to cycling as a lifestyle. Founder Mike Sinyard is an avid cyclist who believes in the transformative power of cycling, an ethos deeply embedded in the company culture. Specialized has come a long way from its modest beginnings, and its journey is a testament to the power of innovation, passion, and a deep love for cycling.Click Here to Check Best Price

Material and Build
The Specialized P.4 Frame is constructed from A1 Premium Alloy with fully butted tubing. The build quality is robust, making it a reliable choice for mountain biking. The frame also features a tapered head tube with diameters of 1.125" at the top and 1.5" at the bottom.
One of the standout features is its versatility. The frame is compatible with both single-speed and geared setups. It also offers internal cable routing and can accommodate internally routed dropper seatposts.
The frame is designed to be compatible with 26" or 27.5" wheels. The rear dropout dimensions are 12mm x 148mm (Boost), and they are adjustable sliding. This makes it easy to switch between different wheel sizes according to your needs.
Color and Warranty
The frame comes in a Satin Rusted Red/White Sage color scheme. Specialized offers a lifetime warranty on the frame and a 2-year warranty on Specialized components. This adds an extra layer of assurance for long-term use.
Geometry and Specs
The geometry of the frame is well-thought-out, with a head-tube angle of 68.5° and a bottom bracket height of 318mm. The frame also features a BSA 73mm BB shell and a 30.9mm seat tube, making it dropper-post compatible.
After personally testing the Specialized P.4 Frame, I can vouch for its performance and durability. Whether you're into single-speed or geared biking, this frame offers the flexibility to suit your style. The lifetime warranty is a cherry on top, making it a worthwhile investment for any mountain biking enthusiast.
