Frequently Asked Questions

For bulk orders, a 30% deposit by T/T (bank transfer) is required.
All products shipped to customers undergo stiffness testing and functional inspection, and are carefully packed before delivery.
- Our series frames use a Toray T800 and T1000 blend – T800 in impact-exposed zones, T1000 where stiffness per gram decides the result.
- FM296, FM306 and FM366 (gravel) are built from T1000, and our lightest road platform FM066 adds T1100.
- For OEM projects we can also build with T700, where toughness and unit cost matter more than stiffness per gram.
- We normally use UD carbon weave, as most customers prefer to apply their own custom paint.
- If no custom painting is requested, we can offer 3K carbon weave instead.
