Budget a year of bike service without inventing replacement intervals
The purchase price is one line. Keeping the bike enjoyable creates several more. Build a service budget from the actual parts and work you can buy locally, then adjust it from measurements and experience rather than pretending every chain lasts a fixed distance.
Four budget lines to keep separate
For a GRARO build, obtain quotes for inspections/service, exact wear parts, labour and a repair reserve. The reserve is money set aside, not evidence that a component will fail. Avoid counting labour twice when it is already included in a service package.
| Line | Basis |
|---|---|
| Inspection/service | Maker intervals and a scoped workshop quote |
| Wear parts | Measured condition; exact chain, pads and tyres |
| Additional labour | Only work not included above |
| Repair reserve | Chosen contingency; not a predicted failure |
Use quantities as assumptions
An illustrative plan might contain €90 service, two €30 chains, €80 for a tyre pair and €40 reserve: €270 allocated in total. These are invented planning inputs, not current market prices or a promise that you need two chains. Replace each amount with a real quote and each quantity with a stated assumption; do not silently turn an unknown into zero.
Assume the €90 service quote includes its labour but excludes the listed chains and tyres. Planned purchases are then €230; the €40 reserve brings the cash allocation to €270, rather than predicting a €270 bill. Any unquoted job or shipping charge remains unknown until scoped and priced.
Let the first year improve the next one
In that same example, if only one chain is bought and the reserve is untouched, spending is €200 and €70 remains unspent. If both chains were bought but one is still on the shelf, spending is €230: the spare is inventory, not cash left over. Carry that distinction into the next plan instead of treating the original €270 allocation as the cost of riding.
Log actual spending and measured replacement reasons. Note wetter routes, travel and changed mileage separately so last year’s bill has context. If proprietary parts have long delivery or expensive shipping, include that route in the budget. Chain wear and cockpit service access often tell you more than a generic annual allowance.
Park Tool’s chain-wear guide uses measurement and the drivetrain maker’s wear criterion. A budgeted chain quantity is a cash-planning assumption, not an instruction to replace a healthy chain. Keep one-time equipment purchases separate using the first-build tool budget.
