Most cyclists know they should maintain their bike. Fewer can actually fix it when something goes wrong fifty kilometres from home. The difference between a ruined ride and a five-minute stop is rarely the tools in your saddle bag; it is whether you have practised using them before you need them.
This guide covers the ten repair skills that solve almost every mechanical problem a road or gravel rider will meet, from a pre-ride safety check to fixing a puncture, a broken chain, a tubeless leak, brake rub, and loose bolts. Each skill is explained step by step, with what to carry, what to keep at home, and when a job needs a professional mechanic instead.
Unlike a maintenance schedule, which tells you when to service your bike, this is about the hands-on skills themselves. Learn them once, practise them at home, and you will never be stranded by a problem you could have fixed. Our separate maintenance guides, linked throughout, cover the routine care that prevents most of these problems in the first place.

Why should every rider learn basic repairs?
Most mechanical problems on a ride are small, predictable, and fixable at the roadside with a few tools. What turns them into ride-ending events is not knowing what to do. On Indian roads, where punctures from glass and thorns are common and the nearest bike shop may be hours away, basic repair skills matter more than in most places.
| Problem | How often it happens | Fixable at the roadside? |
|---|---|---|
| Puncture | The most common by far | Yes, with a tube or plug |
| Dropped chain | Common | Yes, usually in seconds |
| Loose bolt or rattle | Common | Yes, with a multi-tool |
| Brake rub | Common | Often, with a small adjustment |
| Cut tyre | Occasional | Temporarily, with a tyre boot |
| Broken chain | Rare | Yes, with a chain tool and quick link |
| Bent derailleur hanger | Occasional, usually after a fall | Sometimes; often needs a mechanic |
The first row explains why the puncture repair is the single most valuable skill a rider can learn. Almost everything else on this list is rarer, but each one can end a ride if you are unprepared.
Learning these skills also saves money. Many jobs riders pay a workshop to do, such as fixing brake rub or tightening a creaking bolt, take minutes once you know how. For riders just starting out, our things I wish I knew when I started cycling guide covers the habits that go alongside these skills.
How do you do a pre-ride safety check?
The best repair is the one you never have to make. A quick check before every ride catches loose parts, worn tyres, and brake problems before they become failures on the road. According to BikeRadar's guide to essential bike maintenance, the M-check is a basic safety check that works along the bike's main components, ideally before every ride, and it also flags major problems on a bike that has been stored or is being bought used.
| Point | What to check | What a problem looks like |
|---|---|---|
| Front wheel | Quick release or thru-axle tight, wheel spins true | Wobble, loose axle, rubbing |
| Front tyre | Pressure, cuts, embedded glass | Soft tyre, visible damage |
| Headset | Front brake on, rock the bike forward and back | Clunking or play |
| Handlebars and stem | Bars aligned, bolts tight | Bars turn independently of the wheel |
| Brakes | Squeeze both levers firmly | Lever pulls to the bar, weak bite |
| Rear wheel and tyre | Same checks as the front | Loose axle, soft or damaged tyre |
The check takes under two minutes. Squeeze each tyre to check pressure, spin each wheel, pull each brake lever, and grip the front wheel between your knees while turning the bars to check the stem is tight. Lift the bike a few centimetres and drop it on its wheels; any rattle means something is loose.
Tyre pressure deserves particular attention. Riding with tyres that are too soft is one of the most common maintenance mistakes, raising the risk of pinch punctures and making the bike feel slow and vague. Check pressure with a proper gauge regularly rather than by squeezing alone. Our monthly maintenance checklist covers the deeper checks to do less often.
How do you fix a puncture at the roadside?
This is the skill that rescues more rides than any other. The process is simple, but the first attempt always takes longer than expected, so practise at home before you need it.
| Step | What to do | Common mistake |
|---|---|---|
| 1. Remove the wheel | Shift to the smallest rear sprocket first to make the rear wheel easier | Fighting the derailleur on the rear wheel |
| 2. Remove one tyre bead | Use two levers opposite the valve, then run one around the rim | Removing both beads unnecessarily |
| 3. Remove the tube | Pull the tube out, valve last | Losing track of where the hole was |
| 4. Find the cause | Run your fingers carefully inside the tyre | Skipping this and puncturing the new tube |
| 5. Fit the new tube | Inflate slightly to give it shape, valve first | Twisting the tube inside the tyre |
| 6. Refit the tyre | Work the bead on by hand, finishing at the valve | Using levers and pinching the new tube |
| 7. Inflate and check | Check the bead sits evenly on both sides | Riding with the tube trapped under the bead |
Step 4 is where most second punctures come from. The glass shard or thorn that caused the first puncture is often still embedded in the tyre, and a new tube will be punctured again within minutes if you do not find it. Run your fingers slowly around the inside of the tyre and check the tread from the outside.
Tyre levers make the job far easier. The Lezyne Sabre tyre lever set at ₹1,890 is a durable option, and the IceToolz DH tyre lever at ₹990 is designed for both aluminium and carbon rims. Carry a Magene TPU tube at ₹790, which packs very small, and a pump such as the Lezyne HP Drive at ₹2,595.
How do you repair a tubeless puncture?
Tubeless tyres seal most small punctures automatically with the liquid sealant inside. When a hole is too large for the sealant to close on its own, a tubeless plug is the roadside fix. According to Cycling Weekly's puncture repair guide, the tubeless method is to find the puncture and remove the object that caused it, use a plug tool to insert a plug, then inflate the tyre and turn the wheel so the hole sits low and the sealant can do its work.
| Step | What to do |
|---|---|
| 1. Find the hole | Look and listen for escaping air or sealant |
| 2. Remove the cause | Pull out the thorn, glass, or debris |
| 3. Rotate the hole down | Let sealant pool at the hole and try to seal it |
| 4. Insert a plug | Push a plug into the hole with the plug tool, leaving the ends outside |
| 5. Re-inflate | Pump or CO2 to riding pressure |
| 6. Spin and check | Rotate so sealant coats the plug; check it holds |
| 7. Fall back to a tube | If the hole will not seal, remove the valve and fit a tube |
Tubeless is not puncture-proof. Sealant dries out over time, especially in Indian heat, so top it up every few months or it will fail when you need it. Always carry a spare tube even on tubeless tyres, because a large cut or a failed plug means fitting a tube to get home.
A multi-tool with an integrated plug kit saves carrying separate pieces. The Lezyne Rap II 13 Tubeless at ₹2,690 and the Topeak Tubi 18 at ₹2,950 combine standard tools with tubeless repair capability. For deeper tubeless care, our home wheel care guide covers wheels and tyres in more detail.
How do you fix a broken chain?
Broken chains are rare, but they end a ride instantly if you cannot fix them, and walking home in cycling shoes is slow and miserable. According to road.cc's collection of emergency bike fixes, chain breaks are uncommon but worth preparing for, and a quick link is a must-carry item; one tip is to keep a spare taped to the chainstay so it is always on the bike.
| Step | What to do | Why it matters |
|---|---|---|
| 1. Stop and inspect | Find the damaged link | Riding on can damage the derailleur |
| 2. Remove the damaged link | Push out the pin with a chain tool | Leaves two clean ends |
| 3. Prepare the ends | Leave an inner link at each end | A quick link joins two inner links |
| 4. Fit the quick link | Insert each half into the chain ends | The quick link replaces the removed link |
| 5. Seat the link | Put the link on the top run, hold the rear brake, press the pedal | Snaps the quick link closed |
| 6. Check the shifting | Spin and shift through the gears | The chain is slightly shorter now |
The critical detail is that quick links are speed-specific. An 11-speed quick link will not work on a 12-speed chain, so carry one that matches your drivetrain. You also need a chain tool, which is built into many but not all multi-tools; check that yours has one before you rely on it.
At home, removing a quick link is much easier with quick-link pliers. The KMC Missing Link lever at ₹1,069 opens and closes quick links cleanly, which is useful for removing a chain to clean it. Our drivetrain cleaning and chain care guide covers chain wear, which is the main reason chains fail.
How do you deal with a dropped chain or a cut tyre?
These two problems are common, quick to fix if you know how, and easy to make worse if you do not.
| Problem | Roadside fix | Prevention |
|---|---|---|
| Chain dropped off the outside chainring | Shift to the big ring and turn the pedals slowly | Correct front derailleur adjustment |
| Chain dropped inside, onto the frame | Stop pedalling immediately, lift it back by hand | A chain catcher |
| Chain jammed between frame and chainring | Ease it out gently, never force the pedals | A chain catcher, correct shifting |
| Small cut in the tyre | Boot the inside, then fit a tube | Check tyres for cuts after rides |
| Large cut in the sidewall | Boot it and ride home gently | Replace tyres showing damage |
| Tube bulging through a cut | Deflate, boot, re-inflate to a lower pressure | Do not ride on a bulging tyre |
A dropped chain on the inside of the chainring is the one to handle carefully. Pedalling hard with the chain jammed between the chainring and the frame can scratch or crack a carbon frame. Stop, lift the chain back on by hand, and turn the pedals gently. The Absolute Black road chain catcher at ₹3,650 prevents the chain from dropping inside in the first place.
A cut tyre is a problem a new tube alone cannot solve, because the tube will push out through the cut and burst. A tyre boot, placed inside the tyre over the cut, holds the tube in. The Restrap tyre boot kit at ₹1,390 is designed for exactly this. It is a get-home fix; replace the tyre properly afterwards.
How do you fix brake rub and check brake pads?
Brakes are the most important safety system on the bike, and two simple skills keep them working: fixing rub and knowing when pads need replacing.
| Brake issue | Likely cause | Fix |
|---|---|---|
| Disc rotor rubbing | Caliper slightly misaligned | Loosen the caliper bolts, squeeze the lever, retighten |
| Rotor rubbing in one spot | Slightly bent rotor | Gently straighten, or replace if badly bent |
| Rim brake rubbing | Wheel not centred, or brake off-centre | Re-seat the wheel, centre the caliper |
| Squealing disc brakes | Contaminated pads or rotor | Clean the rotor, replace contaminated pads |
| Lever pulls close to the bar | Worn pads, or air in hydraulic brakes | Check pad thickness; bleed if hydraulic |
| Weak braking in the wet | Worn or glazed pads | Replace pads |
The quickest fix for disc brake rub on most bikes is to re-centre the caliper. Loosen the two caliper mounting bolts slightly, squeeze and hold the brake lever to centre the caliper over the rotor, then tighten the bolts alternately while still holding the lever. It solves most rubbing in under a minute.
Check pad thickness regularly, especially after the monsoon, when grit wears pads fast. Riding on worn pads damages rotors and risks brake failure. Contamination is the other common problem: oil or lubricant on the rotor or pads causes squealing and weak braking, and contaminated pads usually need replacing. Our post-monsoon bike check covers brake inspection in detail. Hydraulic bleeding and hydraulic hose work are best left to a mechanic.
How do you check and tighten bolts correctly?
Loose bolts cause rattles, creaks, and in the worst case component failure. Overtightened bolts cause cracked carbon, stripped threads, and crushed handlebars. The skill is getting bolts to the right tightness, not simply tight.
| Component | Why tightness matters | Guidance |
|---|---|---|
| Stem and handlebar bolts | Too loose slips; too tight crushes the bar | Follow the torque value marked on the part |
| Seatpost clamp | Too loose slips; too tight damages carbon | Use carbon assembly paste on carbon parts |
| Crank bolts | Loose cranks damage the interface | Follow the manufacturer's value |
| Disc caliper and rotor bolts | Safety-critical | Follow the manufacturer's value |
| Bottle cage bolts | Rattles if loose | Snug, not forced |
| Thru-axles and quick releases | Wheel security | Firm, as specified |
Most components have their maximum torque printed on them, usually in newton-metres. A torque wrench removes the guesswork and is essential on carbon parts, where overtightening by feel is the most common way riders crack an expensive component. The BikeRadar maintenance guide describes a torque wrench as critical for bikes with carbon components and worth having for any bike.
The Birzman 3 to 15 Nm torque wrench at ₹11,900 covers most bicycle bolts, while the compact Lezyne Pocket Torque Drive at ₹6,695 covers the lower 2 to 6 Nm range used on stems, seatposts, and many small bolts. Our torque wrench and carbon assembly guide explains the process in full.
How do you spot a bent derailleur hanger or shifting problem?
The derailleur hanger is a small, deliberately weak metal part that holds the rear derailleur to the frame. It is designed to bend in a crash or fall so that the frame does not. Recognising a bent hanger saves a lot of confused gear adjustment.
| Symptom | Likely cause | What to do |
|---|---|---|
| Shifting suddenly poor after a fall | Bent derailleur hanger | Straighten with the right tool or replace |
| Derailleur visibly angled inward | Bent hanger | Do not shift into the largest sprocket |
| Chain skips under load | Worn chain, or poor indexing | Check chain wear, then indexing |
| Slow or hesitant shifts | Cable tension or dirty cables | Adjust barrel adjuster, clean cables |
| Noisy chain in some gears | Indexing slightly off | Small barrel adjuster turns |
| Shifting worse after the monsoon | Grit in cables and housing | Clean or replace cables |
A bent hanger is dangerous to ignore. If the derailleur is angled toward the wheel, shifting into the largest sprocket can put the derailleur into the spokes, destroying the derailleur, the wheel, and sometimes the frame. After any fall on the drive side, look at the derailleur from behind the bike before riding on.
Hangers are frame-specific, so keep a spare if you ride far from shops. The Pilo derailleur hanger for Giant and Corratec frames at ₹3,950 is one example; check the exact fitment for your frame. Adjusting gear indexing is a skill of its own, which our guide to adjusting bike gears covers step by step.
What tools should you carry and keep at home?
The right tools split into a small carry kit that lives on the bike and a home kit for the jobs you do in the workshop.
| Item | Carry or home | In-stock option | Price |
|---|---|---|---|
| Tyre levers | Carry | Lezyne Sabre tyre lever set | ₹1,890 |
| Spare tube | Carry | Magene TPU tube | ₹790 |
| Mini pump | Carry | Lezyne HP Drive | ₹2,595 |
| Multi-tool with tubeless kit | Carry | Lezyne Rap II 13 Tubeless | ₹2,690 |
| Tyre boot and patches | Carry | Restrap tyre boot kit and Feextube patches | ₹1,390 and ₹425 |
| Quick link and quick-link pliers | Carry the link, pliers at home | KMC Missing Link lever | ₹1,069 |
| Torque wrench | Home | Birzman 3 to 15 Nm | ₹11,900 |
| Saddle bag | On the bike | Lezyne AERO Caddy | ₹2,990 |
The carry kit above totals ₹9,780 before the saddle bag, or ₹12,770 with it, excluding the torque wrench and quick-link pliers, and it covers punctures, tubeless leaks, cut tyres, loose bolts, and broken chains if your multi-tool includes a chain tool. That is almost every roadside problem you will meet.
For the home workshop, add the torque wrench, a floor pump with a gauge, cleaning supplies, and a chain wear checker. Our essential home maintenance tools guide covers the full home kit, and the maintenance collection stocks the cleaners, lubes, and consumables. Whatever you buy, practise every roadside skill at home once before you rely on it on the road.
Frequently Asked Questions
What is the most important bike repair skill to learn?
Fixing a puncture. It is by far the most common mechanical problem, especially on Indian roads with glass, thorns, and debris, and it can leave you stranded if you cannot fix it. Practise removing a tyre, replacing the tube, and refitting the tyre at home until it feels easy. The key step most riders skip is finding and removing whatever caused the puncture before fitting the new tube.
Do I still need a spare tube if I run tubeless tyres?
Yes. Tubeless sealant closes most small punctures automatically, and a plug handles larger holes, but a big cut or a failed plug still needs a tube to get you home. Carry a tube that fits your wheel size, plus tyre levers. Also check your sealant every few months, because it dries out, particularly in hot Indian conditions, and dried sealant will not seal anything.
How do I know which quick link to buy?
Quick links must match the number of speeds on your drivetrain. A 12-speed chain needs a 12-speed quick link, an 11-speed chain an 11-speed link, and so on, and they are not interchangeable. Count the sprockets on your cassette to confirm your speed. Some brands also have specific compatibility, so matching the brand of your chain is the safest choice. Carry one on every ride.
Why does my disc brake keep rubbing?
The most common cause is a slightly misaligned caliper. Loosen the two caliper mounting bolts, squeeze and hold the brake lever to centre the caliper over the rotor, and tighten the bolts alternately while holding the lever. If the rub is only in one spot as the wheel turns, the rotor may be slightly bent. Also make sure the wheel is fully seated in the dropouts before adjusting anything.
Do I really need a torque wrench?
If your bike has any carbon components, yes. Carbon is easily cracked by overtightening, and judging tightness by feel is the most common way riders damage expensive parts. A torque wrench tightens every bolt to the value printed on the component. Even on aluminium bikes, it prevents stripped threads and slipping parts. A compact 2 to 6 Nm tool covers most stem and seatpost bolts.
What should I do if my chain drops off?
If it drops off the outside, shift to the large chainring and turn the pedals slowly; it will often climb back on. If it drops on the inside, stop pedalling immediately, because forcing it can damage the frame, especially a carbon one. Lift it back onto the chainring by hand and turn the pedals gently. A chain catcher prevents inside drops, and correct front derailleur adjustment prevents most drops altogether.
When should I take my bike to a mechanic instead of fixing it myself?
Take it to a mechanic for hydraulic brake bleeding, bearing replacement, wheel truing beyond minor adjustments, suspension servicing, frame damage, and any repair where you are unsure. A bent derailleur hanger that you cannot straighten confidently also belongs with a mechanic. Safety-critical jobs are worth paying for if you are not confident, and a good mechanic can show you how to do simpler jobs yourself next time.
How often should I practise these repairs?
Practise each roadside repair at home at least once before you need it, and repeat the puncture repair every few months so it stays familiar. The first attempt always takes much longer than you expect, and learning at home in good light is far easier than learning at the roadside in rain, traffic, or fading light. Practising also confirms that your carry kit has everything you need.
