The XMCS Gran Turismo is a one-piece molded carbon frameset with T47 bottom bracket, internal routing, and endurance geometry, praised for its advanced construction, clean interior, and competitive pricing. Weights are around 987g frame, 393g fork, and 133g seatpost, with tire clearance limited to about 35mm. Early production had seatpost tolerance and finishing issues, but the manufacturer has addressed them with a new v2 seatpost and improved decal policy.
Pros
- One-piece molded construction is advanced, resulting in a smooth interior with no overlapping joints and easy cable routing1
- Excellent build quality and finish, with good finishing on critical interfaces like headset seats and bottom bracket threads12
- Competitive pricing undercutting similar frames like Winspace and Elves12
- Comfortable yet aerodynamic ride with stable handling, especially descending, due to long chainstays2
- Responsive customer service from Peter at Carbon Speed, with continuous product improvements12
- Stiff and responsive under power, with no noticeable flex during climbing or sprinting2
- Non-proprietary headset compression system, interchangeable with other brands1
- Well-thought-out design details like internal Di2 battery mount and quality included hardware2
Cons
- Early production frames had seatpost tolerance issues causing sticking/seizing; manufacturer states resolved in later production2
- Some finishing components lacking: poorly threaded compression nut, faulty upper headset bearing, slightly elliptical plug hole1
- Limited tire clearance (max ~35mm with 4mm clearance), long chainstays don't improve clearance2
- Mandatory decals on painted frames (especially "Revenger") unpopular with many buyers; now reduced to XMCS downtube decal only2
- Some riders experience saddle rail slippage requiring higher torque than recommended 6Nm; may be saddle-specific2
- Front brake rub when out of the saddle and moving front wheel side to side, possibly due to fork blade flex or caliper compatibility2
- Nude finish makes blemishes more visible; some filler around hydraulic line ports on fork1
- Does not come with a manual or some expected accessories; handlebar clamp bolts missing from one delivery (XMCS sent replacements)12

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), though some regions see higher pricing (e.g., $1200 discounted from $1600). 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, and a new v2 seatpost with dual-bolt adjustment is now available. Riders report excellent comfort and responsiveness, with some experiencing saddle rail slippage (often resolved by changing saddles) and occasional front brake rub when out of the saddle, possibly due to fork flex or caliper compatibility. A one-piece riser handlebar option is available. Recent builds include a high-stack setup for an older rider who rode 500 km home on delivery day; one buyer received the integrated bar without its clamp bolts, which XMCS replaced. Some find the slim seatpost looks out of proportion. The frameset continues to receive positive long-term reviews, with users noting it is faster than previous bikes and that Peter actively incorporates customer feedback.
