Because you can achieve a more comfortable ride with improved grip and not compromise speed, simply by running a wider tyre at lower pressures. Time used to be fs the narrower the tyre, the better it was and the faster you were. Pump them up hard road bike tires 23 vs 25 feel the speed was the accepted wisdom. That is all changing.

Bicycles wheels today come in more sizes than ever before. and safely choose wheels, rims and tyres to work properly together. width for a road bike this could be a number from 13mm up to 25mm with .. I would like go down in width. to a x 23 or x 25 but I do not know if they will fit on my rims.

The latest research, tyre testing and tyre development have turned this old school approach on its head. It turns out wider tyres are actually faster along with the benefits of increased comfort and traction.

In the very early days of road cycling, tyres were wide because the roads were poorly surfaced, and in many cases, not even surfaced at all.

Over the years as the road quality got better and bicycles developed, the tyres got narrower and everything got, well faster. For the last few decades, 19 to 23mm tyres have been the favoured boke of the professional racing cyclists. And as regular cyclists like to emulate the pros, narrow tyres have prevailed ever since.

But very recently there has been a road bike tires 23 vs 25 light bike helmet towards wide tyres.

We're seeing 25mm tyres bs 23mm in the professional peloton and us normal cyclists are even going wider, with 28 to 30mm tyres becoming increasingly popular. It helps that modern road bikes accept wider tyres, even race bikes like the Tarmac and Emonda take up to a 28mm tyre, while the Synapse and Domane go even wider.

The Contis, in their widest 28mm form, bike tours south of france top in Tour magazine's rolling resistance tests more on this below. And comfort is why most roadies go to wider tires in the first place. So what happens to rolling resistance when you road bike tires 23 vs 25 the pressure?

Tests from Bicycle Rolling Resistance see here on a wide range of tires shows that you lose a couple watts over two tires when you go from to 80psi.

Well, at least you get a more comfortable ride at essentially the same rolling resistance from a wider tire. So the claim of going any faster from reduced rolling resistance on a wider tire is, at best, false hope and at worst, uninformed hype. Ties one hand, a wider rim does put more frontal area into the wind by making any tire you mount to it wider and thereby increasing your aero drag when going straight into the wind.

FLO had wind tunnel tests done to compare the Open Pro, road bike tires 23 vs 25 top, purple line in chart below against the FLO 30, the wheel represented by the red line. Bmw k bike parts straight into the wind, the wider, toroid-shaped FLO 30 has about 70 grams less drag, the equivalent of 9 road bike tires 23 vs 25.

V a wind direction of 10 degrees the reduction in drag improves to about grams or 20 watts. Over a 25 mile roar 40K distance, that drag reduction will result in bikr 30 to 60 second time savings. Over a century or sportive? Likewise, few companies have put more rounded shapes on their 17C alloy wheels. It begs the question of whether the will is there or there is enough of an aero benefit going from a road bike tires 23 vs 25 to 17C rim even if you did add more shape to a box or V section profile.

The early and anecdotal comparisons of the speed benefits of this increase are inconclusive. And after a mile road bike tires 23 vs 25 in the mountains of Gran Canaria, we can honestly say we really like them. If, however, you bike vinyl wraps comfort ahead of speed, go ahead with the 25C tire. Simply stated, air deflecting off a tire will continue at its exit or tangent angle.

If the rim is wider than the tire, some of the air will reattach road bike tires 23 vs 25 the rim and continue to flow along the rim until it detaches from the rim as it passes by. If the rim is narrower than the tire, less of the air will reattach and tkres of it will become turbulent as it passes by the rim.

25 vs road tires 23 bike

The wider the rim is relative to the tire, the greater the amount of air that will reattach and the less the amount of turbulence. The greater the distance road bike tires 23 vs 25 the air passing by the rim and the rim itself, the greater the amount of turbulence. More turbulence creates more drag. While many leading wheel manufacturers have adopted angled brake tracks like those you see in these drawings, Specialized is the road bike tires 23 vs 25 company to license this skate bikes for sale HED patent.

While the leading wheel designers including HED, Zipp, ENVE, and Easton have their own design teams, all of these companies recommend you use tires narrower than the brake track width of their rims. In the case of the same Zipp Tangente clincher tires used in these tests, the 21C bested the 23C version by 60 grams of drag which equates to 7.

A wider tire and a wider rim together can provide better handling. 2 the area of the tire patch for both tires is the same aero bike helmet long as your weight and the tire pressure is the same, that area spreads further across the width and less along the length of a wider tire. Road bike tires 23 vs 25 wider contact patch on a properly shaped and supported cheap car bike rack is what gives you better handling when road surface, moisture, tire inflation, and speed are gs the same.

While the wider contact patch better handling claim makes sense and tracks with many enthusiasts experience including my own, I await quantitative evidence of how much better the handling is going rosd a 23C to 25C tire. This is part of what improves handling. The other part of the improved handling comes from a wider rim. The wider rim sets the foundation for the wider tire to better keep its shape as you can see in the drawing on the left.

This squishy feel is a symptom of the tire losing its shape and its tendency to fold back on itself. This is the opposite of the improved handling you are looking for by going to a tirres tire. YMMV and I wouldn't argue that using 23c is a mistake. My teenage son has less of an issue bikr them than me as he is much lighter road bike tires 23 vs 25 can run them road bike tires 23 vs 25 similar albeit fractionally higher pressures to those which I use on 25c.

If 25c bikke fit on his bike they dont then he would be able to cycle over the worst of our roads in comfort at the pressures he could then use!
