Be careful with the geometry of this frame.
The seat angle is not 73.5º as stated in the Winow size chart – it’s much steeper, more like a time trial bike, over 80º. So the higher you set your seatpost, the shorter the effective top tube becomes.
Normally, I ride a size 58 with a 110 mm stem. I chose this Winow in size L (56) and paired it with a 120 mm handlebar, thinking that if I moved the saddle 1 cm backwards, it would be fine. But this is impossible on this frame. The saddle is positioned as shown in the photo, and I’m still 2 cm short.
Even though the Winow is supposed to be available in a XL frame size, it doesn’t really solve the problem — it only adds about 1 cm to the rear of the bike, which doesn’t help with my issue.
