# Use Case: Road Bike Maintenance Tracking

For road cyclists who put in serious miles, WatchMy.bike helps you keep your bike in peak condition with automatic distance tracking and smart maintenance alerts.

## The Challenge

Road cyclists face unique maintenance challenges:
- **High mileage**: 5,000-20,000+ km per year means rapid component wear
- **Drivetrain wear**: Chains, cassettes, and chainrings need regular attention
- **Tire management**: Worn tires affect performance and safety
- **Multiple bikes**: Training bike, race bike, bad weather bike

Tracking all this manually is tedious. Forgetting leads to premature wear, poor shifting, or worse—mechanical failures during rides.

## The Solution

WatchMy.bike with Strava integration automates the hard part.

### Automatic Distance Tracking
Connect Strava once, and every ride updates your bike and component distances automatically. No logging, no spreadsheets, just accurate numbers.

### Smart Alerts
Set distance-based service intervals and receive notifications when components need attention:
- Chain approaching 4,000 km? You'll know.
- Brake pads at 2,000 km? Alert sent.
- Tires nearing replacement? Dashboard shows it.

## Recommended Setup

### Essential Components to Track

**Drivetrain** (track all of these)
- Chain: Expected lifespan 4,000-5,000 km
- Cassette: Expected lifespan 15,000 km
- Chainrings: Expected lifespan 20,000 km

**Wheels & Tires**
- Front tire: 5,000-6,000 km (less wear)
- Rear tire: 3,000-4,000 km (more wear)
- Brake pads: 2,000-3,000 km

**Maintenance Items**
- Bar tape: Replace annually or when worn
- Cables: Check annually, replace every 2 years
- Chain lube: Every 300-500 km (as service interval)

### Suggested Service Intervals

| Component | Service | Distance |
|-----------|---------|----------|
| Chain | Clean & lube | 300 km |
| Chain | Check wear | 1,000 km |
| Brake pads | Inspect | 500 km |
| Tires | Inspect for cuts/wear | 1,000 km |
| Derailleur | Check adjustment | 2,000 km |
| Full tune-up | Annual | 5,000 km or 12 months |

## Real-World Example

### Sarah's Training Bike
Sarah rides 200 km per week, mostly on her training bike.

**Setup:**
- Connected to Strava
- Chain tracking with 4,000 km lifespan
- Service interval: lube chain every 300 km
- Tire tracking: front at 5,000 km, rear at 3,500 km

**Result:**
- Gets weekly email if any maintenance is due
- Dashboard shows chain at 78% wear
- Replaced rear tire before it failed—avoided a puncture
- Total yearly cost visible: €380 in consumables

### Pro Tips for Road Cyclists

1. **Track your chain religiously**: A worn chain destroys cassettes. Replace at 0.5-0.75% stretch (around 4,000 km for most).

2. **Rotate front/rear tires**: When front hits 2,000 km and rear hits 3,000 km, swap them. Both last longer.

3. **Winter bike tracking**: Track your bad-weather bike separately. Wet conditions accelerate wear.

4. **Race vs training**: If you have a race bike, components last longer (less miles). Adjust lifespans accordingly.

5. **Check cassette with every 2nd chain**: By the time you've used 2 chains, check cassette wear.

## Cost Analysis

With price tracking enabled (Alloy plan), understand your true cost:

**Annual Example (10,000 km/year):**
- Chains (2.5x): €75
- Rear tire (2.5x): €150
- Front tire (1.5x): €90
- Brake pads (3x): €60
- Bar tape: €30
- Cables: €20
- **Total: €425/year**

**Cost per km: €0.04**

Knowing this helps budget and decide on component quality levels.

## Multiple Bikes

Many road cyclists have multiple bikes. WatchMy.bike handles this naturally:

- **Training bike**: High mileage, shorter service intervals
- **Race bike**: Lower mileage, premium components
- **Bad weather bike**: Rougher conditions, more frequent service

Each bike tracks independently. Components can transfer between bikes if needed (swap wheels for race day, etc.).

## Getting Started

1. **Create account** at [watchmy.bike/signup](https://watchmy.bike/signup)
2. **Connect Strava** to import your bikes and enable auto-sync
3. **Add components** starting with chain, cassette, tires
4. **Set service intervals** based on recommendations above
5. **Ride!** Everything tracks automatically

## Why WatchMy.bike?

Unlike Strava's basic gear tracking, WatchMy.bike offers:
- Component-level distance tracking
- Customizable service intervals
- Email maintenance alerts
- Historical service records
- Cost-per-kilometer analysis

Your road bike is a precision machine. Treat it like one.
