Yeah, it’s getting hard to find Chinese frames with proper semi-internal routing these days. Almost every new open-mold is fully hidden through the headset now.
If you’re looking for modern geometry and 38–42 mm tire clearance without fully hidden routing, you still have a few options:
• SPCycle G058 – semi-internal, T47 BB, up to 50 mm clearance.
• LightCarbon LCG071 (older batches) – semi-internal, similar clearance, sometimes still in stock if you ask.
• Some sellers on Taobao/WeChat still have older molds (2020–2022) with semi-internal routing – search for “旧款半内走线”.
Otherwise, you might need to look for used frames or ask manufacturers if they can still do a semi-internal version on request
