The Winspace T1600 is a stiff, aerodynamic, and well-built Chinese aero road bike frameset that delivers excellent performance, especially at high speeds, with a striking design and integrated features. However, it has faced criticism for initial quality control issues, build complexity, and a high price point, though long-term reliability appears solid.
Pros
- Extremely stiff frame that transfers power efficiently, especially during sprints and accelerations.12
- Excellent aerodynamics, especially at high speeds (above 35-40 km/h), with integrated handlebars contributing significantly.12
- Build quality is generally flawless, with no creaks, rattles, or loose parts after extensive use.1
- Surprisingly comfortable for an aero frame, with comfort rated 4/5.2
- Stable and predictable in crosswinds and during descents, giving rider confidence.21
- Striking paint job and unique design features (D-type intakes, winglets) that stand out.2
- Well-protected packaging and inclusion of ancillary components like headset spacers and mounting hardware.12
- Local warranty coverage available in many countries (UK, Europe, US).1
- Easy to build with no major issues, except for minor cable routing challenges.12
Cons
- Initial quality control issues: faulty seatpost clamp screw, difficulty routing Di2 wire due to internal joint, and bike computer mount not compatible with Wahoo out of the box.2
- Frame is very sensitive to wheel choice; wide tires and rims can increase drag more than rolling resistance benefit.1
- Geometry can be tricky, especially for tall riders; size labeling doesn't match top tube length (e.g., XL labeled 540 but has 575mm top tube).1
- High price point, especially in Western markets, with additional costs for handlebar if not included.12
- Tight tire clearance, which may limit options for wider tires or fenders.1
- Aero fins/winglets' effectiveness is questioned; some reviewers are not convinced of their benefit.1
- Cable routing can be complex and time-consuming, especially through chainstays.2
- Less comfortable than some other frames (e.g., Agile or SLC5).2
Key Facts
- Claimed frame weight 1,240g (size 54), measured 1,089g; fork uncut 429g; seatpost 192g; handlebar 330-339g.12
- T47 bottom bracket with 86.5mm shell (T47-86.5).1
- Wind tunnel tested, claimed 5.5W savings at 48 km/h compared to previous model.12
- Frame material is a mix of T800, T1000, and T100 carbon fiber.2
- Tire clearance: at least 32mm.2
- Frameset includes fork, handlebars, stem, and seatpost; handlebar may be extra in some regions.12
- Internal cable routing, not compatible with mechanical shifting; requires Di2 battery housed in frame.1
- Available in multiple colors; price around $2,400 for frameset (with discount).2
Reviews & Ratings
10:38The reviewer discusses the Winspace T1600 Ultra frameset, highlighting its improved stiffness, aerodynamics, and UDH compatibility. They praise the frame's quality and performance, noting it is on par with Western brands. The bike is built with SRAM Force eTap AXS groupset and Winspace Hyper 2 handlebars.
21:18The reviewer discusses the Winspace T1600 Ultra frameset and its accompanying Hyper 2.0 riser handlebars. He praises the bike's stiffness, responsiveness, and stability at high speeds, noting it feels similar to his previous Cervelo Aero. However, he criticizes the riser handlebars for their excessive stack height, poor design of the computer mount, and uncomfortable top section. He also notes the bike is not ideal for climbing due to its weight.
19:00The reviewer discusses the Winspace T1600 Ultra frameset and the Hyper 2.0 riser handlebars. He highlights the frame's updated fork, UDH standard, and overall design. He weighs the components and notes the price increase. He also discusses the fit implications of the riser handlebars and shares his initial impressions.
16:18The reviewer provides a comprehensive review of the Winspace T1600, which is the latest aero frame from Winspace. They built the bike themselves and tested it over 1,000 kilometers. The reviewer states the T1600 is a stiff, fast, and surprisingly comfortable racing frame that feels racier and more aggressive than the Agile or SLC 5. It excels at high speeds (above 35-40 km/h), feels planted and stable in crosswinds and during descents, and is described as an 'absolute joy to ride.' The frame features a striking paint job and signature D-type intakes on the rear, which are said to contribute to lateral stiffness. However, the reviewer encountered several quality control issues during the build process, including a faulty seat post clamp, difficulty routing internal cables, and a problematic bike computer mount. They conclude that while the frame performs excellently, these initial issues should not occur at its price point.
04:35The reviewer discusses the T1600 as a new generation airframe unveiled by Windspace, highlighting its unique features and design choices. They mention that the T1600 is inspired by fighter jets, with distinctive seat stays featuring vent-like openings for improved aerodynamics. The frame also has a sharper, more arrow-like head tube and a thinner seat post compared to its predecessor, the T550. The reviewer notes the use of a mix of T800, T1000, and T100 carbon fiber, sealed true axles, and a tire clearance of at least 32 mm. The bike shown at the launch event weighed 7.3 kg and was equipped with Lun Mega wheels and a Shimano Dura Ace Di2 group set. The T1600 is currently available in black, white, and yellow, with a frame set priced at 9,300 Chinese yuans in China. The reviewer expresses curiosity about the frame's wind tunnel performance and its reception in Western markets.
16:00The reviewer provides a detailed overview of the Winspace T1600, a Chinese superbike/hyperbike. They discuss its packaging, components, and various features. The frame arrives well-protected with bubble wrap and plastic bags, including the fork, seat post, and handlebars. The reviewer notes the frame's dimensions, weight, and the inclusion of ancillary components like headset spacers, top caps, and mounting hardware. They highlight the clean design of the fork, the immaculate paint finish of the frame, and the aerodynamic features such as the pointy head tube and aero fins.
