The Most Worthwhile Bike Upgrades: Spending Money Where It Counts

The Myth and Reality of Upgrades

Every cyclist has had the thought at some point: if I swapped out that part, would I ride faster and more comfortably? The world of bicycle components is vast, ranging from small accessories costing a few hundred dollars to top-tier wheelsets costing tens of thousands, with so many choices it can make your head spin.

But the reality is, not every upgrade delivers a proportional improvement in feel. Some seemingly expensive modifications may only bring marginal gains, while certain relatively affordable upgrades can transform your riding experience. Today, we’ll take the most practical approach to help you prioritize your bike upgrades.

First Priority: Tires (Budget NT$1,000-3,000)

Many people’s first thought is upgrading the wheelset, but you should actually start with tires. Tires are the only contact point between your bike and the road, and their impact on ride quality far exceeds what most people imagine.

Why Are Tires So Important?

• Rolling Resistance: The difference in rolling resistance between a high-quality tire and an entry-level tire can reach 10-15 watts. In a 40-kilometer time trial, that translates to a difference of over a minute.
• Grip and Safety: Good tires provide better traction in wet conditions and corners, directly affecting your safety.
• Comfort: Modern high-quality tires paired with appropriate tire pressure can provide suspension-like comfort.

Recommended Options

The mainstream width for road bike tires has already increased from 23mm to 25-28mm. Wider tires offer lower rolling resistance and better comfort at the same tire pressure. The Continental GP5000, Vittoria Corsa, and Pirelli P Zero Velo are all excellent performers.

Second Priority: The Three Contact Points (Budget NT$2,000-8,000)

The three contact points refer to the saddle, bar tape, and cycling shoes—the three places where your body directly touches the bike.

Saddle

A saddle that fits you is far more important than an expensive one that doesn’t. Everyone’s sit bone width and riding position are different, and finding the right saddle requires trial and error. Many bike shops offer saddle demo services; making good use of them can save you from wasting money. A good saddle isn’t necessarily the most expensive, but it must be the one that fits you best.

Bar Tape

High-quality bar tape provides better grip, vibration damping, and slip resistance. A good roll of bar tape costs anywhere from three or four hundred to just over a thousand NT dollars, yet it can significantly improve comfort on long rides. Lizard Skins, Supacaz, and Fizik all have solid options.

Cycling Shoes and Pedals

If you’re still using flat pedals, upgrading to a clipless pedal system is arguably one of the most impactful investments for pedaling efficiency. Clipless pedals allow you to apply power throughout the entire pedal stroke, not just the downstroke half. An entry-level Shimano SPD-SL pedal set plus a pair of well-fitting cycling shoes will cost around five to eight thousand NT dollars in total.

Third Priority: Wheelset (Budget NT$8,000-40,000)

The wheelset is the upgrade where you can feel the biggest difference on a bike, but it’s also one of the most expensive.

What a Wheelset Upgrade Brings

• Weight Reduction: Entry-level bikes typically come with wheelsets weighing 1,800-2,000 grams. Upgrading to a mid-to-high-end wheelset can save 300-500 grams or more. Since wheels are rotating mass, the weight reduction is more noticeable than saving weight on the frame.
• Aerodynamics: Deep-section wheels provide a clear aero advantage at high speeds, especially above 30 km/h.
• Stiffness and Drivetrain Efficiency: Good wheelsets have smoother hubs and better spoke lacing patterns, resulting in less energy loss when pedaling.

Budget Allocation Advice

If your budget is around ten thousand NT dollars, consider Taiwanese aluminum wheelsets like SCOPE or mid-range options from major brands. With a budget above twenty thousand, you can start looking at carbon fiber wheelsets, and domestic carbon wheels offer solid choices at this price point. Above thirty thousand, you can choose carbon wheelsets from international brands like Zipp, ENVE, and Roval.

Fourth Priority: Braking System (Budget NT$3,000-15,000)

Upgrade from Rim Brakes to Disc Brakes?

If your frame supports disc brakes and you’re currently using rim brakes, this is an upgrade worth considering but it’s a major undertaking. Disc brakes perform far better in wet conditions and long descents than rim brakes, but you’ll need to replace the wheelset and possibly the handlebar setup, and the cost is substantial.

Upgrades Within Rim Brakes

If you’re staying with rim brakes, upgrading from entry-level Claris/Sora brake calipers to 105 or Ultegra level can noticeably improve lever feel and braking power. Paired with good brake pads (like SwissStop), overall braking performance improves significantly. A pair of 105-level brake calipers costs around two thousand NT dollars, making it a very worthwhile upgrade.

Fifth Priority: Drivetrain (Budget NT$5,000-30,000)

Full Groupset Upgrade

Upgrading from Shimano Claris (8-speed) to 105 (11-speed or 12-speed), or from 105 to Ultegra, delivers smoother shifting and a wider range of gear ratios. However, drivetrain upgrades usually require replacing the entire groupset (derailleurs, shifters, cassette, chain, and possibly crankset), which is costly.

Partial Upgrade

If your budget is limited, consider replacing only the cassette to get a wider gear range. For example, switching from an 11-28 cassette to an 11-32 or 11-34 makes climbing much easier. This upgrade costs just over a thousand NT dollars, but you may need to swap the rear derailleur (from short cage to long cage).

Upgrades Not Recommended as Priorities

Frame

Unless your frame no longer fits your needs (too big, too small, wrong geometry), a frame upgrade usually offers poor value for money. The same budget spent on wheels and tires will deliver a more noticeable improvement in feel.

Carbon Fiber Seatposts and Stems

The weight difference on these components is usually only a few dozen grams, which has a negligible impact on riding performance. Unless you’ve already upgraded everything else, these aren’t worth prioritizing.

Electronic Shifting

Electronic shifting systems like Di2 or eTap are certainly cool, but the cost of upgrading from mechanical to electronic shifting is extremely high, while the actual performance gains are limited. This is more of a “want” than a “need” upgrade.

Upgrade Priority Summary

1. Tires → Lowest cost, most noticeable improvement
2. Contact Points (saddle, bar tape, cycling shoes) → Directly affects comfort and efficiency
3. Wheelset → Overall improvement in weight and aerodynamics
4. Brakes → Major improvement in safety
5. Drivetrain → Smoother operating experience

Remember, the best upgrade is always the rider. Before spending big money on equipment, invest more time in training and riding skills—you’ll find that’s the most cost-effective investment of all.
