Do you handle road bikes or mountain bikes?
We do not handle professional competition models. We focus only on traditional steel and aluminum frames, such as track bikes and daily-use bikes, and do not include modern aerodynamic frames.
What if I can't find the frame I want?
Of course. If you provide the model name, we will register it. However, please note that we may not be able to proceed if it does not comply with our policy or if the necessary information cannot be found.
