POLYGON STRATTOS S3|A highly cost-effective aluminum road bike that makes your first road bike experience even more enjoyable

 

Its stability makes you want to ride further. A bike that naturally expands the fun of road cycling.

Many people want to try road cycling but feel uneasy about the aggressive riding position or worry about wobbling on thin tires. The POLYGON "STRATTOS S3" is an entry-level road bike that eases these initial concerns while allowing riders to truly experience the "joy of riding."

With a low center of gravity design and a longer wheelbase, it achieves stability that even beginners with drop handlebars can handle with ease. It possesses a character that naturally encourages riders to challenge themselves with long rides and hill climbs, in addition to urban commuting.

The flat-shaped top tube and downtube provide both vibration absorption and aerodynamic performance. Furthermore, the carbon fork with an aluminum steerer ensures a reassuring balance of rigidity and comfort.

Another attractive feature is its full SHIMANO SORA drivetrain, including the crankset, making it a bike that feels more complete than its price suggests. It's a very easy model to choose as your "first road bike."

 

Features

  • High stability due to low center of gravity and long wheelbase design
  • Improved vibration absorption and aerodynamic performance with a flat top tube shape
  • Achieves manageable rigidity with a carbon fork featuring an aluminum steerer
  • Equipped with a full SHIMANO SORA (2x9 speed) groupset
  • High cost-performance specification with SORA unified throughout, including the crankset
  • Lightweight riding performance suitable for long rides and hill climbs
  • Designed to be easy and safe for beginners with drop handlebars
  • Available in vivid and impactful Orange / Charcoal colorways

 

SPEC

  • Frame: Aluminum (flat top tube & down tube)
  • Fork: Carbon fork with aluminum steerer
  • Main Components: SHIMANO SORA (2x9 speed)
  • Brakes: SHIMANO SORA
  • Colors: Orange, Charcoal
  • Sizes: S (162-170cm), M (168-176cm), L (174-181cm)

 

This model is quite well-balanced as a "first road bike."

The stability provided by its low center of gravity design is particularly noticeable, giving a sense of security even to those unfamiliar with drop handlebars. It resists wobbling even at speed, allowing for confident riding over long distances.

Another key point is the consistent use of SORA right down to the crankset. This ensures a smooth shifting feel and operation without incongruity, providing a level of satisfaction that exceeds its price.

It's a road bike that can be enjoyed for everything from city riding to long tours and hill climbs, making it highly recommendable for those who want to "enjoy their first bike for a long time."

"You'll regret it if you don't know" - The true identity of POLYGON

  • POLYGON STRATTOS S3 Frame
  • Many of you might be thinking, "I've never heard of POLYGON..."

    Actually, this brand is the in-house brand of "Insera Sena," a massive factory that has produced OEM for famous manufacturers worldwide.

    With an annual production capacity of over 1 million units and a robust quality control system, it's a bike truly made by "manufacturing pros."

 

Beginner-friendly design with emphasis on stability

  • POLYGON STRATTOS S3 Geometry
  • The STRATTOS S3 features a low center of gravity and a long wheelbase, making stability its key characteristic.

    Its gentle handling response means that even first-time road bike riders won't feel intimidated.

    With carbon fork for vibration absorption, it offers a stress-free riding experience from city commuting to cycling tours.

 

"Full SORA" at this price point is honestly quite excellent.

  • SHIMANO SORA Components
  • The main components are consistently SHIMANO SORA (2x9 speed).

    While many bikes in this price range often downgrade the crankset, having a complete set is a significant advantage.

    It's recommended to enjoy it as is for now, and then consider upgrading the wheels or brakes as you get more comfortable.

 

This might be your last chance to buy at this price.

A solid frame design, reliable SORA components, and this price. Honestly, models with these conditions are becoming scarcer each year.

This bike is just right for anyone looking to start road cycling, or those who are "a little curious" and want to take the plunge.

Supplies are limited, so if you're interested, check it out soon.
