How to Make a Mountain Bike Faster

Riding a mountain bike that feels sluggish can really take the fun out of hitting the trails. Luckily, there are a number of ways to make your mountain bike faster and improve its overall performance. With some relatively simple upgrades and adjustments, you can turn your slow trail bike into a more responsive and aggressive machine.

In this comprehensive guide, we’ll cover the key steps and modifications to make your mountain bike faster and more efficient on the trails.

Key Steps to Boost Your Mountain Bike’s Speed and Performance

Here are the top methods to make your mountain bike faster:

  • Upgrade to a lighter wheelset
  • Install a dropper seatpost
  • Switch to wider tires with a faster rolling tread
  • Adjust tire pressure for conditions
  • Upgrade drivetrain components
  • Improve riding position and technique
  • Reduce weight overall
  • Maintain bike well

We’ll explore each of these upgrades and adjustments in detail below. Implementing even just a few of these can help you ride faster downhill, accelerate quicker on flats, and climb more efficiently.

Upgrade to Lighter Wheels

One of the most effective ways to pick up speed on a mountain bike is reducing rotational weight by installing lighter wheels. Mountain bike wheels take a lot of abuse and stock wheels often weigh over 2,000 grams.

Switching to a high-end carbon fiber or lightweight alloy wheelset in the 1,500 to 1,800 gram range can shave off significant weight and dramatically improve acceleration, nimble handling, and climbing capability.

Lighter wheels also allow you to get up to speed faster after slowing down for corners or obstacles. The key is looking for a wheelset designed specifically for aggressive trail or all-mountain riding, with a wider internal rim width and beefed up hubs.

Brands like Reynolds, ENVE, Industry Nine, and DT Swiss make race-ready carbon wheelsets in the 28-30mm internal width range that can handle tough riding while dropping hundreds of grams of weight.

Install a Dropper Seatpost

Adding a dropper seatpost is one of the best upgrades for going faster on a mountain bike. Being able to lower your seatpost and saddle out of the way with the press of a lever lets you more confidently descend and tackle technical sections in a more aggressive attack position.

Dropper posts allow you to pedal with full leg extension on climbs, then drop your saddle down and out of the way on descents. This lets you shift your weight and center of gravity more freely for better control, stability, and handling speed through technical terrain.

Many riders report being able to descend significantly faster after installing a dropper post since it allows them to move around more freely on the bike without the saddle restricting them. Brands like Fox Racing Shox, RockShox, KS, and Crankbrothers all make high performing dropper posts to improve descending speed and control.

Switch to Wider Tires with a Faster Rolling Tread

Most stock mountain bike tires are on the narrow side and have heavily lugged treads that create a lot of rolling resistance. Switching to wider tires in the 2.3-2.6 inch range with a moderately lugged, ramped center tread can drastically reduce rolling resistance.

The wider tire footprint also offers more grip and control through corners, allowing you to carry more speed. Plus, the extra volume lets you run lower tire pressure for increased traction and small bump compliance, while still minimizing the risk of pinch flats.

Some fast rolling tire models to look at are the Maxxis Rekon, WTB Ranger, Schwalbe Racing Ray/Ralph, and Continental X-King. Run wider rims in the 30-40mm internal width range and experiment with tread patterns to find the fastest rolling tire for your local trails.

Adjust Tire Pressure for Conditions

Running your tires at the optimal inflation pressure for the trail conditions can also help them roll faster. In Short, drop your pressures a few PSI lower than normal on loose or rocky terrain to increase grip.

But on smoother hardpack or flow trails, you will have to increase the pressure slightly to minimize tire squirming and reduce rolling resistance. Wider tires allow you to run lower pressures without pinch flatting.

Always use a quality gauge and adjust pressure in small increments of 2-3 PSI to find the ideal tire pressure for speed, protection, and handling. Lower pressure leads to faster rolling and better bump absorption on rough terrain.

Upgrade Drivetrain Components

Upgrading key drivetrain components like your rear derailleur, cassette, and crankset can make a big difference in shifting performance and power transfer.

Installing a 10-50t wide range 12-speed cassette and rear derailleur gives you better gear spacing for faster acceleration and maintaining momentum over rough terrain.

Switching to a lighter crankset or narrow-wide chainring up front can also smooth out pedaling and improve power transfer for snappier acceleration.

Improve Riding Position and Technique

How you position yourself on the bike and your overall riding technique can be nearly as important as equipment upgrades when it comes to riding faster. Here are some key tips:

  • Lower and center your body position for descents
  • Shift weight back and lower your heels when going downhill
  • Pump terrain features to gain momentum
  • Pedal smoothly in circles without bouncing
  • Stay loose and allow the bike to move underneath you

Practice cornering faster, Braking judiciously before corners to carry speed through them. Improving technical skills like bunny hops, drops, jumps, and rock gardens also allows you to carry more momentum and go faster. Taking skills clinics and riding with faster friends can help improve technique.

Reduce Weight Overall

Beyond wheels, look for other areas to shave weight off your bike through component upgrades. Swapping out heavier fork, handlebars, saddle, pedals, and tires for lightweight versions can make a notable difference in how quickly your bike accelerates and climbs.

Removing any unnecessary accessories and keeping your tool kit minimal also helps pare down pounds. Consider converting to a tubeless setup by installing tubeless tires and sealant. This allows you to run lower tire pressure without pinch flats and reduces the extra tube weight.

Maintain Your Bike Well

Keeping your mountain bike well-tuned and maintained is key to optimizing speed and performance. Here are some key maintenance tips:

  • Keep the chain clean, lubricated and at optimal tension
  • Replace worn cassette, chainring and chain
  • Tighten any loose bolts and creaks
  • Check hubs are greased and spinning freely
  • Keep suspension fork and shock serviced yearly
  • Replace brake pads when worn
  • Check wheels are true with no side-to-side wobble

Taking care of routine bike maintenance ensures everything is running smoothly and safely, reducing resistance. Always inspect frame, suspension pivots, chain, and brakes before hitting the trails. Carrying minimal bike tools and supplies allows you to make any trail-side repairs and adjustments needed to keep your bike rolling fast.


With the right mix of component upgrades, adjustments, and improved riding technique, you can dramatically boost your mountain bike’s speed and capabilities on the trail.

Lighter wheels, a dropper post, fast-rolling tires, optimal tire pressure, and a modern 1x drivetrain are key upgrades to consider. But don’t overlook dialing in your riding position, skills, and overall fitness.

Riding with faster friends, taking clinics, and pushing your capabilities on more challenging terrain are great ways to increase speed as well. Work on both fitness and skills development.

By applying the tips outlined in this guide, you’ll be able to upgrade your current mountain bike into a faster and more responsive shredder on the trails.

Just take things step by step and focus on the changes that make the biggest difference for your riding style and local terrain.


What 3 upgrades make the biggest difference in mountain bike speed?

The 3 most impactful upgrades for faster mountain biking are:

  1. Lighter weight wheelset
  2. Modern 1x drivetrain
  3. Dropper seatpost

What tire pressure should I run for fast mountain bike tires?

Tire pressure for faster rolling mountain bike tires depends on your weight, tire width, and trail conditions. A good starting point is:

  • 2.3-2.5″ tires: 25-28 PSI rear, 23-25 PSI front
  • 2.6-2.8″ tires: 22-25 PSI rear, 20-22 PSI front

Adjust in small increments based on speed, grip, and preventing pinch flats.

What maintenance helps keep a mountain bike running fast?

Frequent mountain bike maintenance for optimum speed includes:

  • Cleaning and lubricating the chain
  • Replacing the chain at optimal intervals
  • Checking spoke tension and wheel trueness
