Carbon Fiber Bike Frames: The Foundation of Your Dream Build

Building a custom bicycle is the ultimate expression of a rider’s identity. It requires an understanding of geometry, mechanics, and your own riding ambitions. At Winspace, we provide the high-performance chassis for that vision. Our carbon fiber bike frame collection offers the ideal starting point for mechanics, racers, and enthusiasts who demand UCI-certified performance without the inflated industry markups.

Whether you are assembling a dedicated crit racing machine, a featherweight climber, or a rugged adventure rig, our framesets serve as a race-proven platform. We manufacture our own products using genuine Toray T800 and T1000 carbon fiber, ensuring transparency in materials and engineering. This is smart performance for the modern cyclist.

Aero Racing Frames: Pure Speed and Stiffness

For riders who prioritize watt-saving efficiency and high-speed stability, our Aero Racing platforms are engineered to cut through the wind.

• T1550 & T1600 Series: These are our flagship road bike framesets used by UCI Continental teams. Featuring aggressive geometry, fully internal cable routing, and high stiffness at the bottom bracket, these frames transfer every bit of power directly to the road. The T1550 Gen 2 refines this legacy with T47 threaded bottom brackets and improved tire clearance.
• Design Philosophy: We utilize Computational Fluid Dynamics (CFD) and wind tunnel validation to shape tubes that minimize drag. The result is a chassis that holds speed effortlessly on the flats and responds instantly during a breakaway.

Superlight All-Rounders: Defying Gravity

When the road points upward, weight matters. Our Superlight series targets climbers and riders who want a responsive, agile feel on mixed terrain.

• SLC Series (Super Light Climbing): The SLC 3.0 and SLC 5.0 represent the pinnacle of our lightweight engineering. By optimizing the carbon layup schedule, we achieved a lightweight road bike frame that often dips below 800g (depending on size and paint) without sacrificing structural integrity.
• Agile: For those seeking a balance between aerobic efficiency and snappy handling, the Agile platform offers a versatile geometry suitable for long days in the saddle and punchy climbs alike.

Endurance Platforms: Comfort Meets Performance

Not every ride is a sprint. For Gran Fondos and all-day epics, rider fatigue becomes the biggest enemy.

C5 & C5 Aero: This series features a geometry with a slightly higher stack and shorter reach compared to our T-series. This positions the rider in a more sustainable posture for long-distance efforts. The carbon layup is tuned to absorb high-frequency road vibration, keeping you fresh for the final kilometers. It proves that an endurance road bike can still look and feel fast.

Gravel Bike Frames: Adventure Without Limits

The paved road is just a suggestion. Our gravel platforms are designed for the explorer who refuses to turn back when the tarmac ends.

• G3 & G2 Gravel: A robust gravel bike frame must balance durability with weight. The G3 Gravel features massive tire clearance (up to 50mm), numerous mounting points for bikepacking bags, and a geometry that remains stable on loose descents while staying nimble on climbs.
• Versatility: These framesets are compatible with both 1x and 2x drivetrains and support both 700c and 650b wheel sizes, allowing you to configure the bike exactly for your local terrain.

Why Build with Winspace?

• Manufacturer Direct Transparency: We control the production process from raw Toray carbon sheets to the final paint job. No "black magic" marketing, just honest engineering.
• Race-Proven Reliability: Winspace frames have competed at the UCI Continental level and the Olympics. If a frame can survive professional racing, it will handle your local crit series with ease.
• The "Bundle" Advantage: Simplify your build by pairing our frames with Lún HYPER wheels and integrated handlebars. This ensures perfect aesthetic matching and mechanical compatibility.

FAQ: Technical Specs & Buying Guide

Q1: How do I choose the correct size for a Winspace frame?

A: Sizing varies between our Aero (T-series), Climbing (SLC), and Endurance (C5) platforms due to geometry differences. Do not rely solely on "Small" or "Medium" labels. We strongly recommend comparing the Stack and Reach measurements from our geometry charts against your current bike to ensure the perfect fit.

Q2: What is the maximum tire clearance on these frames?

A: Modern cycling demands wider tires for speed and comfort.

• Road Frames (T1550 Gen 2 / SLC 3.0): Optimized for 28mm, but generally support up to 32mm tires (measured width), depending on your rim's internal width.
• Gravel Frames (G3 / G2): Designed for adventure, supporting up to 50mm (700c) or 2.1" (650b) tires for maximum off-road capability.

Q3: Are these frames compatible with mechanical groupsets?

A: Yes. All our frames support both Electronic (Di2, eTap, EPS) and Mechanical drivetrains.

Note for Aero Frames: Models with fully internal cable routing (like T1550) are compatible with mechanical shifting, but we recommend using high-quality housing and professional installation to ensure smooth shifting performance through the integrated headset system.

Q4: What Bottom Bracket (BB) standard do your frames use?

A: We prioritize reliability and ease of maintenance.

• T1550 Gen 2 / T1600 / G3: Typically feature a threaded T47 BB for creak-free performance and easy service.
• SLC 2.0 / Older models: May use BB86 press-fit.
• Tip: Always check the "Specs" tab on the specific product page to order the correct Bottom Bracket for your crankset.

Q5: What is included in the box when I buy a frameset?

A: We provide the proprietary essentials. Typically, a frameset includes: Frame, Fork, Seatpost, Headset (bearings/spacers), and Thru-Axles. Specific models also include the derailleur hanger and routing grommets. Integrated handlebars are sold separately or as part of a "Bundle".
