Essential Bike Maintenance Checks Before a Long Ride

Five Minutes That Save a Whole Day

There is a particular kind of disappointment that only arrives six miles from home, in the rain, when you realise your rear tyre is soft and your multi-tool is on the kitchen table. Long rides — whether it's a coast-to-coast route, a Welsh trail centre loop or a 100-mile sportive — punish small neglected things. A brake pad worn past its limit, a chain stretched beyond saving, a quick-release lever not quite tight enough. None of these announce themselves on the driveway. All of them announce themselves at the worst possible moment.

The good news is that a proper pre-ride check takes five to ten minutes once you know what you're looking at. Do it the night before a big ride if you can, then repeat a shorter version on the morning. Here's the routine I use before anything longer than a couple of hours.

Tyres: Pressure, Tread and Hidden Debris

Tyres cause more abandoned rides than anything else on a bike. Start by checking pressure with a gauge — a decent track pump with an accurate dial. Thumb pressure lies, especially when you're in a hurry.

As a rough guide, cold-tyre pressures sit around 90–100 psi for 25mm road tyres, 35–45 psi for 40mm gravel rubber, and 22–28 psi for a mountain bike on 2.3in tyres. Adjust for your weight and load: a fully laden touring bike wants more, and a wet, rooty trail wants a little less. Always check when tyres are cold — a tyre pumped to 100 psi in a warm garage reads differently once you're on a cold, damp climb in the Peak District.

Then run your eyes and fingers around the tread. Look for:

• Flints, glass or thorns embedded in the rubber — pick them out with a small screwdriver or your fingernail before they work their way through
• Cuts or bulges in the sidewall, which mean the tyre is finished regardless of tread depth
• Worn tread on the rear, where power and braking load sit
• For tubeless setups, a slosh test: if you can't hear sealant moving inside, top it up

Check the valve is sitting straight and the lockring (if you use one) isn't over-tightened against the rim.

Brakes You Can Trust in British Weather

We ride in a country that specialises in grit, mud and sudden downpours, so brakes deserve real attention. Squeeze each lever firmly. It should feel solid and progressive, not spongy, and it shouldn't pull all the way to the bar. Spongy hydraulic brakes usually mean air in the system or a low fluid reservoir — sort that before you go, not at the top of a descent.

On rim brakes, look at the pads. Most have a wear line or groove; once that's gone, replace them. Worn pads also need re-toeing and re-aligning so they hit the rim squarely and don't rub the tyre.

On disc brakes, check the friction material — below about 1mm and they're done. Listen for a metallic scrape when you spin the wheel: that's often a contaminated or worn pad, or a slightly bent rotor. Spin the wheel and watch the rotor pass through the caliper; a wobble you can see with the naked eye is worth truing. Finally, test both brakes at walking pace before you commit to the road.

Chain, Gears and Drivetrain Tidy-Up

A clean, lubricated chain is the single cheapest performance upgrade you can make. Wipe it down with a rag, then apply one drop of lube per link while backpedalling. Wet lube for winter and wet rides, dry lube for dry summer conditions. Leave it a few minutes, then wipe off the excess — a chain coated in sticky grime attracts grit and wears everything faster.

Check wear with a chain checker if you have one. Beyond 0.5% stretch on most setups, replace the chain before it takes the cassette and chainrings with it. A cassette costs far more than a chain.

Then shift through the full range while the bike is in a work stand or held up by the saddle. Listen and watch for:

• Skipping or hesitation in the middle of the cassette
• The chain dropping off the largest sprocket or into the spokes
• A rear derailleur that looks twisted or sits too close to the cassette
• Frayed or kinked gear cables, particularly on older mechanical setups

Nuts, Bolts and Quick-Releases

Vibration loosens things. Go around the bike with the appropriate hex key or spanner and check stem bolts, seatpost clamp, saddle rails, bottle cage, rack mounts and mudguard stays. Use a torque wrench where you can — carbon components in particular do not forgive over-tightening.

Quick-release levers are the classic oversight. A correctly closed lever should leave a faint mark in your palm as you push it home, and it should sit pointing backwards along the chainstay or upwards in line with the fork leg, tucked out of harm's way. If the lever closes with almost no resistance, it's too loose; if you can't close it at all, it's too tight. Thru-axles should be snug but not brutal — check them with a proper key rather than guessing.

Lift the bike and spin each wheel. Look for wobbles, a dragging brake or a tyre that's not seated evenly. Then hold the front brake on and rock the bike forwards and back to feel for play in the headset.

The Final Roll-Out Check

Before you clip in, do one last sweep: lights charged and working, computer or phone mounted securely, saddlebag packed with a spare tube, tyre levers, pump and a multi-tool. Give the bike a bounce on the ground to settle anything loose, and glance at the weather forecast one more time. Tell someone where you're going and when you expect to be back.

It sounds fussy. It isn't. Riders who check their bikes rarely get stranded, and the five minutes you spend on the driveway is five minutes you'll be glad of somewhere far from home, with the wind at your back and miles still to go.
