Five Fettles, One Multitool: The Cheap Jobs That Quietly Save Your Season

There is a particular kind of Saturday morning joy in fixing your own bike. It is not the smug sort. It is the quiet satisfaction of tracking down a tick, tick, tick to a slightly tired cable, making one small adjustment, and heading out with the lanes still quiet and the kettle still warm.

The trouble is that most of us default to the bike shop for anything more involved than pumping tyres. Fair enough—mechanics exist for a reason, and a good local shop is worth every penny. But there is a middle ground between a two-minute tyre check and a full service. It is the thirty-quid workshop: a multitool, a borrowed workstand, a few consumables, and the willingness to have a go.

First, The Ground Rules

This is not a column about rebuilding suspension or facing a bottom bracket shell with a file and optimism. Leave the high-stakes stuff alone. If a job needs a torque wrench, a press, or a tool that costs more than your winter tyres, it is probably a bike shop job. The five fixes below are the ones that reward patience and punish ham-fistedness only mildly.

A borrowed workstand is the single biggest upgrade to home fettling. Ask in your local riding group, check whether your town has a bike co-op, or see if a neighbour has one gathering dust. Working at waist height rather than crouched over a upturned bike changes everything. It also saves your back for the ride.

1. Index the Gears Without Panic

If the chain skips, clatters, or hesitates between cogs, start here. Put the bike in the workstand, shift to a middle cog, and pedal by hand. Look at the rear derailleur from behind. If the chain is not running cleanly through the jockey wheels, you have found your starting point.

Use the barrel adjuster at the rear mech or the shifter—tiny quarter-turns, not heroic half-turns. If shifts are slow going up the cassette, add a touch of cable tension. If they are slow coming down, back it off. Check the shift after every adjustment. This is not a job for brute force. It is a job for a cup of tea and two minutes of patience.

Before you touch anything, check the mech hanger. A slightly bent hanger makes indexing impossible. Which brings us neatly to job two.

2. Straighten a Mech Hanger—Carefully

A bent hanger is the quiet cause of a thousand bad gear shifts. You can spot it by eye from behind the bike: the mech cage should hang roughly parallel to the cassette. If it is wonky, stop adjusting cable tension and deal with the hanger first.

Here is the honest bit. A proper hanger alignment tool is the right way to do this. They are not cheap, but many bike co-ops lend them, and some local shops will straighten a hanger for a few quid while you wait. Do not attack an aluminium or carbon frame with an adjustable spanner and a prayer. If you cannot borrow the right tool, pay someone who has it. That is not defeat; it is good sense.

If you do have access to the tool, the technique is gentle: fit it, sight the alignment, and make small corrections. Aluminium hangers fatigue. If it has been bent back more than once, replace it. They are usually a tenner or so online, but check the exact hanger number before ordering. UK riders: your local shop can often match one from a photo, which beats guessing at an eBay listing.

3. Silence a Brake Rub

A rubbing brake is the most annoying free speed loss in cycling. With the bike in the stand, spin the wheel and listen. Is it a constant shhhh, or a rhythmic tick? Constant rub often means the caliper is not centred. Rhythmic tick can mean a slightly bent rotor or a sticky piston.

For a cable disc brake, loosen the caliper mounting bolts a hair, squeeze the lever to centre the caliper, and retighten evenly. For hydraulic brakes, check that the wheel is seated properly first. Then look at pad clearance. If one piston is lazy, a careful clean around the pistons with isopropyl alcohol and a gentle push back with a plastic tyre lever can help. Do not poke metal tools near hydraulic seals.

Rim brakes are simpler: check the pads are not worn to the wear line, clean the rim track, and adjust the cable tension or spring tension so both pads hit at the same time. A multitool with a decent set of hex keys is usually all you need.

4. Chase the Creak Properly

Creaks are detective work. The noise is often not coming from where you think. Before you start replacing bottom brackets, clean and grease the easy suspects: seatpost, saddle rails, headset, pedals, and thru-axles. A dry seatpost in a dirty frame can sound like a terminal drivetrain issue.

Take the seatpost out, wipe it, and refit with the correct grease or carbon assembly paste. Check the saddle clamp bolts—often a four or five millimetre hex on a multitool. Clean the pedal threads and refit with a smear of grease. Check the headset preload: if there is play, adjust it; if it is binding, back it off. None of this requires a full workshop, just a methodical approach and the discipline to change one thing at a time.

If the creak survives all that, it might be bottom bracket or suspension related. That is your cue to book it in.

5. Check the Chain Before It Checks You

A worn chain eats cassettes and chainrings. A chain checker is one of the cheapest tools you can buy—often under a tenner—and it pays for itself the first time it saves you a new cassette. Drop it into the chain, read the wear, and if it is past the limit, replace the chain.

A multitool with a chain breaker lets you size and fit a new chain at home. Use a quick link for refitting, and make sure you buy the right speed chain for your drivetrain. UK tip: your local shop will often fit a chain you bought elsewhere for a small labour charge if you are unsure. That is still cheaper than a full drivetrain replacement.

The Thirty-Quid Reality Check

A decent multitool might already live in your saddlebag. A borrowed workstand costs nothing but a favour. The thirty quid goes on a chain checker, a tube of grease, a couple of cables, and maybe a proper hanger alignment tool loan. What it should not go on is a drawer full of eBay specials that round off bolt heads and make you swear.

False economies are real. Cheap cable cutters fray cables. Cheap hex keys chew soft bolts. Cheap torque wrenches are often worse than no torque wrench. Buy once, borrow where you can, and ask your local shop when you are out of your depth. That is not cheating. That is how everyone learns.

The point is not to avoid the bike shop forever. The point is to know which jobs you can own, which ones you can bodge safely, and which ones deserve a professional. Start with the five above. Your bike will run quieter, your wallet will thank you, and you might just enjoy the fettling as much as the ride.
