Sprok, your bike garage.
Track your bikes, components, and service history in one place. Sprok watches the wear so you know what needs attention, and when.
For cyclists who can tell you their tyre pressure but not when they last changed their chain.
Your garage
Every bike you own, in one place.
Add as many bikes as you ride. Each one gets its own page: photos, specs, components, and a full service history. The bike is the centre of Sprok, not a spreadsheet row. You're building a garage you're proud of.
Multiple bikes. Photo galleries. Specs. Full timeline. Garage health at a glance.
Component wear
Sprok knows how worn your parts are. You don't have to guess.
Sprok tracks distance and time on your components, live, from the moment you add it. Wear follows the part, not the bike. Move your fork to a different bike and its history comes with it. Service it and wear resets, but the history stays. Nothing is lost.
- GoodEverything is within range. Keep riding.
- Needs attentionWorth looking at soon. Don't leave it too long.
- UrgentService this before your next ride.
Service
Log a service in one action, across the whole bike.
When you bring your bike in for a full service, you shouldn't have to log every part one by one. Sprok's bike-wide checklist shows everything on the bike, with urgent parts pre-checked. Tick what was serviced, confirm, and wear resets on everything you touched. That's it.
Tyres
Tyre wear has no honest number. So Sprok doesn't invent one.
There's no percentage that can tell you how worn a tyre is. Rubber compound, terrain, pressure, rider weight, they all matter, and no app can see them. What works is what mechanics have always done: look at the tyre. So Sprok asks you to check in. You give a verdict, Sprok logs it and reminds you to look again in about 1,000 km.
Checked in. Next look in about 1,000 km.
Reminders
Sprok works while you're not looking at it.
When something in your garage needs attention, Sprok sends a daily digest to your inbox. One email, only when there's something worth knowing. Every email has a real one-click unsubscribe.
Equipment
Every part of the bike has a place.
Drivetrain, brakes, wheels, suspension, cockpit and seat, frame and accessories. Each category is either wear-tracked or recorded as a spec entry, depending on what makes sense for that part. You choose what to add. Nothing is mandatory.
Beta
Free while we're in beta.
No paid tier. No trial period. No credit card. Sign up, add your bike, and start tracking. If you have feedback, there's a feedback button in the app. It goes straight to the person who built it.
