Thank you for your reply.

What is the quality of the carbon like? Has it been processed cleanly? What are the tolerances for the head tube and bottom bracket? What is the quality of the materials that are supplied or installed, such as derailleur hangers, headset, derailleur hanger, etc.? Thank you for your opinion.

Thank you for the lively discussion. I sent Tideace a few questions about quality control and this was their response:

Quality Control & Certification
Every frame undergoes strict QC procedures including:

High-pressure strength testing

Vibration fatigue testing

Alignment inspection

Visual and finish inspection
Our frames are made in ISO-certified facilities and comply with EN/ISO testing standards.

Comparison with Other Brands (Tavelo, Quick Pro, Winspace)
We focus on direct-to-rider value, offering high-quality carbon frames at factory pricing. Compared to other brands, our differences include:

Lower branding and marketing cost

OEM-level production experience (we manufacture for multiple overseas brands)

Customizable paint and geometry options
While brands like Winspace invest heavily in global branding and sponsored teams, we keep pricing competitive without compromising material quality or safety.

It sounds to me as if they manufacture the frames themselves, and when I watch the video and read the accompanying description, that must be the case. But I could be wrong.

Hello dear community

Does anyone have any experience with the frame manufacturer Tideace? How are the frames and forks in terms of mechanical quality, the construction quality of the carbon structure, the overall workmanship, and the parts used, such as the headset for the fork, etc.? I am interested in the FM-CR266 frame. Has anyone already used it and gained experience with it in terms of riding characteristics and stiffness? Is this frame suitable for mountain stages?
What are the alternatives in terms of frames that are very good for mountain stages? I live in an area where it is mainly uphill (from 450 meters to 2400 meters). Thank you very much for your support.
