Reviews & Ratings
The reviewer provides a detailed analysis of the XM Carbon Speed XMCS Gran Turismo frameset. They note it is a one-piece molded frame, which is complex and expensive to manufacture, contrasting it with typical multi-piece frames that have adhesive joints. The frame arrives with a fork, handlebars, seat post, headset spacers, bearings, and other accessories. It has a nude carbon finish with clear lacquer, a T47 bottom bracket, internal routing, an oversized headset, and dropped seat stays. The reviewer highlights the clean internal construction with no visible joints, good finishing on critical interfaces, and overall solid build quality. They mention it is not as high-end as brands like Evolved Chamers and lacks some accessories like a manual, but it is also not as expensive. They plan to build and ride it for further subjective feedback.

Frequently Asked Questions
What is the price of the frameset?
Prices range from approximately $1000 for unpainted frameset without handlebar to $1350-$1500 for painted frameset with handlebar, depending on options and exchange rates.
What bottom bracket standard does it use?
The frameset uses T47 threaded bottom bracket standard, which provides good compatibility and ease of maintenance compared to press-fit systems.
