Bike Upgrades

The order, and why it is that order

Every item below is cheaper than a single replacement shifter. They are listed by how much they change the ride per dollar spent, which is a different question from how much they cost or how good they sound.

1. Tires

The single biggest change available to a cheap bike, and it is not close. Budget bikes ship with heavy, stiff, puncture-prone tires because that is where a manufacturer saves money without anything appearing on the spec sheet — the listing says “700c” and stops. A better tire rolls faster, grips better and punctures less, and you feel all three on the first ride.

Which tire depends on where you ride: road tires for pavement, gravel tires if you leave it, and the width guide if you are not sure what will fit.

2. Tire pressure — free

Not a purchase, and it belongs this high anyway. Most new riders run their tires far too hard because the number molded on the sidewall is a maximum, not a recommendation. Too much pressure makes the bike skittish and genuinely slower on real road surfaces, because the bike bounces instead of the tire deforming.

What it needs is a floor pump with a gauge you can read, because the pressure you cannot measure is the pressure you cannot fix. The pressure guide has the numbers.

3. The three contact points

Saddle, bar tape and pedals — the only three places you touch the bike. Nothing else on a bicycle has the same ratio of cost to comfort, and discomfort is what actually stops people riding. A bike that is slightly slow gets ridden. A bike that hurts does not.

• Saddle— the biggest single comfort variable, and the one most likely to be wrong out of the box.
• Bar tape— the cheapest comfort upgrade that exists, and it wears out anyway.
• Pedals— budget bikes ship plastic ones that flex and break.

4. Brake pads

Cheap, safety-critical, and the one upgrade that changes what the bike does in the rain rather than how it feels in the dry. On a rim-brake bike a better compound is the closest thing to a free improvement in wet braking. Which pad fits which caliper is the part that trips people up.

5. Everything else, much later

Wheels, cassettes, cranks, carbon anything. These are real upgrades that real riders make, and they are the wrong purchase on a first bike — usually because a decent version of the part costs a meaningful fraction of what the whole bike cost. The skip list explains each one.

Where the groupset actually sits

It sits below all of this, for one reason that has nothing to do with quality: shifters. On a drop-bar bike the shifters and brake levers are the same part, and they are the most expensive component in the groupset. A complete gear upgrade on a bike that cost a few hundred dollars routinely approaches the price of the bike.

That does not mean groupsets do not matter. They matter enormously when you are choosing which bike to buy— it is the most informative line in any listing, which is why the groupset explainer exists and why every bike we recommend has its groupset named. The claim here is narrower and it is about money already spent: upgrading the groupset on a bike you already own is nearly always the wrong place for the next hundred dollars.

The honest ceiling

There is a point where upgrading a cheap bike stops making sense, and it arrives sooner than most people expect. The rough test: once the parts you are considering add up to more than about half what the bike cost, you are no longer upgrading a bike, you are assembling a worse one than you could have bought.

The exception is anything that moves to the next bike. Pedals, a saddle you have proven suits you, a floor pump, tools, a computer — none of those are attached to this bike in any meaningful sense. Wheels and drivetrain parts mostly are. That distinction is worth more than any ranking on this page: spend freely on what you keep, and reluctantly on what you leave behind.

If you are still shopping rather than upgrading, start with the buying sequence instead — buying the right bike beats upgrading the wrong one every time.
