Let me tell you about the bike that came into our workshop last autumn.
The rider had been putting off a service for about eighteen months. "It still works fine," they said. "Just a bit noisy."
When we put it on the stand, the full picture became clear: the chain was at 1.8% stretch. The rear cassette was cogging. The brake pads were contaminated with oil. The bottom bracket had play that the rider had learned to compensate for without realising.
The quote for the work came to Β£380. A service eighteen months earlier would have been Β£220. The difference β Β£160 β bought a lot of rides. Except the bike had been unrideable for the preceding three months.
This is the story I see repeated every week.
Why People Skip Services
I get it. Β£120 for an Advance Service, Β£220 for a Full Service β it feels like a lot when the bike "seems fine."
The thinking goes: if it's not broken, why fix it?
The problem is that bikes don't break suddenly. They degrade. The chain stretches over months. The brake pads wear down over rides. The cables fray incrementally. The bearings lose their preload gradually.
What We Find During Services
A service isn't just maintenance. It's a diagnostic.
On bikes that haven't been serviced in over a year:
- Chain stretch above 0.8% β found on approximately 80% of bikes
- Contaminated brake pads β found on roughly 40%
- Frayed gear or brake cables β found on about 30%, often invisible from the outside
- Bearing play in headsets, hubs, or bottom brackets β found on 1 in 4 bikes
- Tyre sidewall UV damage β found on roughly 20%
The Maths Of Prevention vs Repair
Skipping a service for 18 months:
- Chain replacement: Β£45-65
- Cassette replacement: Β£60-100
- Brake pad replacement: Β£20-40
- Labour for repairs: Β£80-150
- Days without your bike: typically 3-7
Getting a Full Service every 12 months:
- Full Service cost: Β£220
- Full inspection, all adjustments, chain cleaned or replaced, brakes stripped and rebuilt, gears indexed, bearings checked
- Days without your bike: 0 β we come to you
The service costs less than the repairs it prevents. And you keep riding.
The Degradation Curve
A chain at 0.5% stretch shifts crisply. At 1%, it starts to skip under load. At 1.5%, it accelerates wear on the cassette and chainrings. At 1.8%, it's damaging the entire drivetrain with every pedal stroke.
Replace the chain at 0.8% = Β£45. Wait until 1.5% and you're replacing chain, cassette, and chainrings = Β£200-350.
What An Advance Service Actually Covers
Our Advance Service at Β£120 includes:
- Gear and brake cable inspection and replacement if needed
- Brake pad inspection β measuring remaining material, checking for contamination
- Brake and gear adjustment β indexing, lever feel
- Tyre inspection β tread, sidewalls, pressure
- Chain inspection and measurement
- Quick-release or bolt-through axle check
- Basic bearing check on hubs, headset, bottom bracket
- Tyre inflation to correct pressure
The Honest Truth
I don't think everyone needs their bike serviced every six months. But if your bike hasn't been touched in over a year, and you're riding it regularly β you're accumulating deferred maintenance costs. The bike isn't "fine." It's running on borrowed time.
The rider who services their bike regularly spends roughly Β£120-220 per year on maintenance. The rider who skips services spends Β£200-500 on emergency repairs.
