12:39The reviewer discusses the Winspace T1550 Gen 2 frame, which costs $1,780, and compares his custom build to the complete bike offered by Winspace. He notes that Winspace recently started selling complete bikes with customizable options. The frame is the same for both builds, but his custom build includes a power meter and higher-end components.
19:57The reviewer builds a crit racing bike using a Winspace T1550 Gen 2 frame, which he custom spray-painted for a unique look. He describes the frame as firm, low, slightly longer, with a good stack height for an aggressive position. The frame is part of a mostly Chinese-component build aimed at balancing quality and cost.
