For small orders, we accept PayPal, bank transfer, or Western Union.

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.

1. For our standard-weight frames, we use Toray T700 and T800 carbon fiber.
2. For customers looking for lightweight frames, we use T800 and T1000 carbon fiber.

1. We normally use UD carbon weave, as most customers prefer to apply their own custom paint.

Yes. A premium carbon road bike frame delivers significant performance and comfort advantages that aluminum cannot match: Weight savings – A high‑quality carbon frame (like Mondince FM126 at 760 g) is typically 30‑40% lighter than an equivalent aluminum frame, making climbing and acceleration noticeably easier. Vibration damping – Carbon naturally absorbs road buzz, reducing hand and back fatigue on long rides. Aluminum transmits far more vibration. Stiffness‑to‑weight ratio – Carbon can be engineered to be extremely stiff in the bottom bracket for efficient power transfer, yet compliant in the seat stays for comfort. Infinite fatigue life – Unlike aluminum (which has a finite fatigue life of 10‑15 years), carbon has no fatigue limit and can last indefinitely when properly cared for. Aerodynamic shaping – Carbon can be molded into complex aero shapes (Kamm tail, truncated airfoils) that are impossible to achieve with metal tubes. All Mondince frames are independently tested to 1.3× ISO 4210 – 30% above the industry baseline. For a more detailed comparison, see our carbon vs. aluminum vs. steel material guide.
