FrameVIN — What Actually Fits Your Bike
A bicycle compatibility and provenance tool that identifies the exact standards and measurements a bike uses, from bottom brackets to headset, axles, seatposts, and tyre clearance.
Why it surfaced
FrameVIN treats a bicycle frame like a car with a VIN, then backs each fitment answer with a source, document hash, or physical measurement. It also plans to check used-bike listings against photos and claimed specifications, while publishing its compatibility vocabulary as open JSON and CSV.
