Okay, this is huge! Just yesterday, on April 25, 2025, Winspace introduced a new generation of its aero frame called the T1600. And you are among the first to hear about it. Outside of Chinese internet and social media, almost nobody knows about it yet. Based on how this frame looks, I think it’s going to cause a lot of buzz. So let’s take a look at what’s new based on the info I gathered from multiple Chinese videos. Here is my short summary:

Or here is the original video from a Chinese influencer.

Winspace spent a long time thinking about how to improve the T1550, a frame they already considered great. For the new T1600, they found inspiration in fighter jets.

The most unique feature of the T1600 is its seatstays. They have two vent-like openings that look a bit like gills. These vents should improve aerodynamics, although no exact figures are available yet. It’s clear that one of the goals was to make the frame stand out and create buzz. Will it work? Time will tell. But I guess they add complexity to the manufacturing process.

The frame also features a sharper, more arrow-like head tube designed to improve airflow. The seatpost is thinner than on the T1550 and resembles a razor blade—okay, maybe not literally, but you get the idea. Overall, the T1600 uses sharper leading edges and seems more aggressive. However, an aerofoil is known to create the least drag, so I’m curious about the T1600’s wind tunnel numbers. Winspace seems confident in its design choices, so I hope they prove them with some testing.

UPDATE: The T1600 was tested against the T1550 Gen 2 with Winspace ZERO SL handlebar in the Fuji Aero Performance Centre wind tunnel, and the T1600 (with new handlebar) should be 5.5W faster at 48kph.

The integrated handlebars are also new. They have a textured area near the stem, probably for a better grip and a wider connection between the stem and bars. Unlike the Winspace Zero SL, the T1600’s handlebars have a glossy finish and pretty sharp leading edges.

The frame is built from a mix of T800, T1000, and T1100 carbon fibers and should be reinforced. But I admit, I didn’t understand this part of the video well, and I’m not sure what they mean by reinforced. As usual with Winspace, the thru-axles are sealed, contributing to a cleaner design.

Tire clearance appears to be at least 32mm and might even fit wider tires. This is today’s standard, as wider wheels and tires are getting more popular.

The bike shown at a launch event was equipped with Lún MEGA wheels and a Shimano Dura-Ace Di2 groupset. It weighed 7.28 kg, which is impressive for an aero bike. With lighter wheels and components, dropping the weight below 7 kg should be easy.

The T1600 is currently available in black, white, and yellow. They have details of the Tour de France stages, which may not suit everybody, so I believe more colors will be introduced soon.

The frameset with handlebars is priced at 19,300 CNY ($2650) in China. Prices in Western markets will likely be higher, possibly around $3000. That’s a pretty steep price tag for a Chinese frame. But maybe it’s time to shift our perspectives on Chinese frames.

I am super curious about how the Western audience will react to this frame and whether it will stir in the same way as SEKA Spear. The unique seatstays alone would make me consider buying one. They would be a great conversation starter.
