# Best answer: What psi do pro cyclists use?

Contents

“It depends on the road surface, but 10 years ago the standard was 23mm tires at 8 or 8.5 bar, or 115, 120 psi,” Brown said. “And now it’s 25mm for regular road racing and 7 to 7.5 bar for front and rear, so a little less than 100 to 110 max on the bikes.” So what’s the deal?

## What is the best PSI for a road bike?

Tire inflation basics

A typical road tire should be inflated to something between 90 and 120 PSI. Mountain bike tires, on the other hand, tend to run at much lower PSI.

## What size tire do pro cyclists use?

Race bikes: 23-25mm, increasingly up to 28mm

They are narrow to reduce weight and improve aerodynamics. The common standard for many years was 23mm (it used to be even narrower) but that has changed as the pro peloton adopted wider tyres, with 25mm slowly becoming the default choice.

## What PSI should 25mm tires be?

Suggested tyre pressure for road bike tyres (25mm) – for a ≤70Kg rider: Inner tube tyre: 90PSI (6.2Bar) Front / 93PSI (6.4Bar) Rear. Tubeless tyre: 80PSI (5.5Bar) Front / 83PSI (5.7Bar) Rear.

## What PSI should my 29er be?

For a 29 inch tire, the critical range is likely between 18 and 28 psi, depending upon your weight, your skills and the terrain. For Plus tires, that range is around 11 to 15 psi, and for fat tires (4-inch and wider), the sweet spot might be between 6 and 10.

## What PSI should bicycle tires be?

To find your bike tire pressure, you initially need to know what tires are on your bike. Narrower tires need more air pressure than widespread ones, with road tires needing about 80 to 140 psi (pounds per square inch) and hybrid tires needing 50 to 70 psi.

## Should I inflate tires to max psi?

RAY: Under no circumstances should you inflate your tires to maximum pressure. Not only will you risk a blowout, but you’ll diminish your ability to control the car because your handling and braking will be much, much worse.

## Do any pro cyclists use clinchers?

Clincher tyres, as used by most amateur cyclists for decades, have made occasional forays into professional road racing, but there has never been widespread adoption of this tech within the professional peloton.

## Are 28mm tyres faster than 25mm?

Yes, they are still aerodynamically superior, but the rolling speed advantages outweigh this, certainly at the speeds of regular cyclists and even up to the speeds reached by keen amateurs, even professional cyclists are now running 25mm tubulars and sometimes 28mm for the Spring classics.

## Are 28mm tires faster than 32mm?

‘Also a 28mm tubeless tyre is the fastest setup [in rolling resistance tests]. … And a 32mm tyre is only about 2 watts slower than an equivalent 28mm tyre.

## What PSI should a hybrid bike tire be?

Hybrid bike tires require pressure levels between those of road and mountain bikes. This is usually in the 50 to 70 psi range. Kids’ bikes have the lowest recommended inflation, typically 20 to 40 psi. Keep in mind that these are called “recommendations” for a reason, though.

## What PSI should my mountain bike tires be?

Most mountain bike tires are rated for 25-50 PSI. Road tires are usually 80-120 PSI. Gravel tires are often 40-80 PSI. While they are a good starting point, those ranges are too broad and conservative for most riders.
