The reviewer has used the Winspace T1600 as his primary race and training bike for approximately seven months, covering around 6,000 kilometers. He states the bike has been completely faultless, raced in Germany, the Netherlands, and the UK, and tested in a wind tunnel. The frame is described as extremely sensitive to wheel choice, and the integrated handlebars are highlighted as a significant source of aerodynamic gains. The build quality is praised as flawless, and the bike is noted for being extremely stiff. The reviewer mentions the bike comes as a frameset including the fork, handlebars, stem, and seat post, with the rest being bolt-ons. He also discusses the bike's geometry, noting the XL size has a longer top tube than expected.
AI Summary
Pros
- Completely faultless over 6,000 km of use
- Extremely stiff frame
- Flawless build quality
- Excellent aerodynamics, especially with the included handlebars
- Easy to build with no issues
- Good handling
- Successful for the reviewer's racing
- Local warranty coverage available in many countries
Cons
- Frame geometry can be tricky, with the XL size having a longer top tube than the labeled 540 size suggests
- The frame is extremely sensitive to wheel choice; a wide tire and wheel combination can increase drag more than the rolling resistance benefit
- The reviewer is not totally convinced the winglets provide a significant aerodynamic benefit

The 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.
