CYCLINGÂ NEWSÂ & REVIEW:
By Columnist Genevieve Whitson – Professional CyclistÂ
There is an ongoing debate in the world of cycling as to whether the 23 or the 25 width tyre is faster. So, let’s explore this concept now.
In more recent times it does feel like people are swaying towards 25 with evidence showing that close to 75% of riders are using the wider tyres. But, then again, is it just personal preference? And just what do cyclists prioritise, is it road grip, ride comfort, traction, aerodynamics or CRR (coefficient of rolling resistance)?
The 23 Width Tyre
As the classic tyre for road cyclists for years, this tyre has always done a good job. It cuts through the road surface nicely. You can pump the tyre pressure pretty high, especially if you just need pure speed for say a TT. But, with large advancements in bike technology, this may not even be necessary anymore. Plus, these tyres are skinny, so you may feel more twitchy in the wet. Consequently, Â this means less confidence cornering. So, do you need something bigger?
The 25 Width Tyre
Relatively new on the block, the 25 width tyre is proving hugely popular. In fact, there is a new wave of cyclists saying that this is now the tyre of choice. Simply said, the slightly wider tyre gives you more grip and there is now evidence that it has faster-rolling resistance. Therefore, rotating faster than the 23 – meaning more speed for the same amount of pedalling.
In addition, you can also run the 25 with lower pressure – around 90 instead of say 100, which may make you feel safer – since it’s a slightly larger tyre. Consequently, giving you more grip and control for descending and cornering.
And finally from a budget perspective – durability. A tyre with a larger surface wears out slower so the 25 could be cheaper in the long run. I’ve ridden both and I am finding myself swaying towards the 25, simply because a lot of UK racing and riding is in the wet and overcast conditions so
I’ve ridden both and I am finding myself swaying towards the 25. Why? Well,  simply because a lot of UK racing and riding is in wet, overcast conditions, so I want to stay upright. In saying that, most of the Tour de France riders are now using a 25. so there you go, you make the choice.
But, remember the choice is entirely yours. We’re all different, and have specific preferences.
