The XMCS Gran Turismo frameset is praised for its innovative one-piece molded construction, high-quality finish, and competitive pricing, offering excellent value for an aero road bike. Some minor issues with included components and early production seatpost tolerance were noted, but overall it is considered a strong contender against more expensive brands.
Pros
- Innovative one-piece molded construction results in smooth interior and no visible joints, enhancing strength and ease of cable routing.1
- Excellent build quality and finish, with top-tier carbon layup and attention to detail on critical interfaces.12
- Competitive pricing undercutting similar frames from Winspace and Elves.12
- Comfortable yet aerodynamic ride with stable handling, especially on descents.2
- Stiff and responsive under power, with no noticeable flex during climbing or sprinting.2
- T47 bottom bracket with good threads and no issues.1
- Good tire clearance (up to ~35mm) and long chainstays for stability.12
- Non-proprietary headset compression system and interchangeable bearings.1
- Excellent customer service from Peter at Carbon Speed.1
Cons
- Early production frames had seatpost tolerance issues causing sticking/seizing, though later production is said to be resolved.2
- Finishing components (compression nut, headset bearing) had quality issues requiring replacement or tapping.1
- Mandatory decals on painted frames (especially 'Revenger') are unpopular.2
- Slack seat tube angle (73°) combined with setback seatpost may limit forward saddle position for some riders.2
- Limited tire clearance (max ~35mm) and potential toe overlap with larger tires.2
- Nude finish makes blemishes more visible (one small speck noted).1
- Does not come with a manual or some expected accessories.1

Reviews & Ratings
17:34The 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.
15:17The reviewer discusses the XMCS Gran Turismo (also referred to as Carbon Speed) frame, highlighting its one-piece construction, competitive pricing, and overall high frame quality. He notes that the frame is made in a single mold, which is technically complex and results in a smooth interior with no overlapping joints, making cable routing easy. The frame is EPS molded, leading to a better finish. However, he experienced issues with some finishing components, such as a poorly threaded compression nut and a faulty upper headset bearing. Despite these, he praises the customer service and considers the frame a high-quality product that undercuts competitors like Winspace and Elves.
The XM Carbon Speed XMCS Gran Turismo frameset is an aero road bike with endurance geometry, featuring high stack and low reach for a comfortable yet aerodynamic riding position. It uses T800 carbon fiber with T47 bottom bracket (T47i internal preferred for stiffness/aero), UDH hanger, and internal cable routing. The frame is praised for its build quality, smooth ride comfort, and stable handling due to long chainstays (422mm). Price ranges from ~$1009 (unpainted) to ~$1350 (painted with handlebar). Weight is approximately 997g for frame (size 56, raw carbon) and 383g for fork. Paint jobs are available but decals (especially "Revenger") are controversial; newer frames may have fewer mandatory decals. Some early units had seatpost tolerance issues (sticking), but manufacturer states these are resolved in later production.
