Maintenance Calculators

The UK's wet, gritty roads are notoriously harsh on bicycle components. Rain, road salt, and debris accelerate wear on chains, brake pads, and tyres far more quickly than in drier climates, making proactive maintenance essential rather than optional. Our chain wear calculator estimates when your chain needs replacing based on your mileage and the conditions you ride in — preventing the costly cascade of worn cassettes and chainrings that results from running a stretched chain too long.

Brake performance is safety-critical, especially on wet descents and through the stop-start traffic of British towns and cities. The brake pad calculator helps you anticipate replacement timing so you are never caught out with worn pads on a rainy commute. For hydraulic disc brake users, the bleed volume calculator provides the correct fluid quantity for your specific calliper and lever combination, making home maintenance straightforward and avoiding air bubbles that compromise braking feel.

The service interval calculator takes your weekly mileage and riding conditions to produce a personalised maintenance schedule covering everything from chain lubrication and gear indexing to headset and bottom bracket servicing. For riders going tubeless, the tubeless conversion calculator lists everything you need — sealant volume, rim tape width, and valve length — to make the switch confidently. Organisations like Cycling UK offer maintenance courses at local groups across the country, and our tools complement those skills by helping you plan and budget for the parts you will need throughout the year.
