Stop guessing
at standards.
SpecMatch: Bike Parts walks motorcycle and bicycle riders through every axle, freehub, bolt pattern, and chain-line spec before a wrench ever touches a mismatched part.
Built for the bench, not the boardroom.
Every feature exists because a build got held up over a spec sheet somewhere. We turned those hold-ups into a fast, branching decision tree.
Branching Logic Engine
Answer a few questions about your frame, hub, or drivetrain and the tree narrows to the exact standards that matter for your build.
Bike & Moto, One Tool
Bicycle axle spacing and motorcycle final-drive sprockets run through the same rigorous matching logic, tuned to each platform.
Instant Verdicts
No more cross-referencing three forum threads. Get a clear compatible, incompatible, or adapter-needed call in seconds.
Save Your Build Spec
Keep a running list of the standards on your current bike or bike so every future upgrade gets checked against what you already run.
The branching check, live.
Pick a platform, then match a frame or wheel standard against the component you're eyeing. This mirrors the exact logic tree inside the app.
About Us
🔧 We're a small crew of wrench-turners, frame builders, and shop-floor tinkerers who got tired of return boxes stacking up because a "standard" freehub wasn't standard at all. SpecMatch: Bike Parts was built in the same spirit as the tools on our bench — practical, precise, and allergic to guesswork.
🎯 Our mission is simple: strip the ambiguity out of every drivetrain and component upgrade, whether you're respacing a hardtail fork or swapping a final-drive sprocket on a street bike. Compatibility should be confirmed before checkout, not discovered with a torque wrench in hand.
🧭 At the core of the app is a branching compatibility checker that walks you through your platform, your frame or hub standard, and the component you're eyeing — then hands you a clear verdict instead of a shrug. No more cross-referencing forum threads and decade-old PDFs just to confirm an axle will seat.
🏁 One more reason it matters: a mismatched standard doesn't just cost money, it costs a ride day. We built SpecMatch so your next upgrade bolts on clean the first time.
Measure your standards. Match your parts. Ride without surprises.
Privacy Policy
SpecMatch: Bike Parts is built to run entirely on your device. We do not collect, store, or transmit any personal data, and we designed the app so that no data collection is even necessary for it to work. Below is exactly how that plays out.
-
Information We Collect
We collect nothing. SpecMatch does not request your name, email, location, device identifiers, or any account information. The compatibility engine, spec lookups, and saved build lists all operate without ever asking who you are.
-
How We Use Information
Because no information is collected, none is used, analyzed, profiled, or sold. There is no usage tracking of which standards you look up, which builds you save, or how often you open the app.
-
Data Storage
Any build specs, saved standards, or compatibility history you create stay stored locally on your own device. Nothing is uploaded to a cloud server, and we do not operate a backend database of user activity.
-
Third-Party Services
SpecMatch contains no third-party analytics software development kits, no advertising networks, and no external trackers. The compatibility logic runs entirely within the app itself, with no outbound calls to third-party services.
-
Data Security
Since your saved builds and lookup history never leave your device, there is no transmission for anyone to intercept and no remote database for anyone to breach. Standard device-level security (like a passcode or device encryption) protects your local data.
-
Children's Privacy
SpecMatch does not knowingly or unknowingly collect personal information from anyone, including children under 13. Because no data collection mechanism exists in the app, there is nothing to gather from any user regardless of age.
-
Your Control
There are no accounts to create and none to delete. If you'd like to remove your saved build specs and compatibility history, simply uninstalling the app permanently erases everything, since it was never stored anywhere else.
-
Changes to This Policy
If our approach to privacy ever changes, we'll update this page with a new effective date and a clear summary of what's different, so you can review it at a glance before continuing to use the app.

Questions about this policy can be sent to privacy@specmatchbikepartsapp.com. We're glad to walk through exactly how your data (or lack thereof) is handled.
