Current thinking says wider tyres at lower pressures create less rolling resistance. Cyclist decides to test the theory on the road.
By aboutrims with a 17mm internal width started to become fairly common, which add millimeters to the labeled tire width.
This mostly got ignored, and we all still went riad what road bike tires 23 vs 25 label said. Then, things started to get strange. Over time, other manufacturers started to make road rims in the range of mm for internal width. Given all this history and hub-bub, I decided to poll some of the major wheel manufacturers and industry experts, to see where we stand today.
I wanted to know a couple things: Inwhat is the current best or fastest tire size for top-level amateurs and professionals? This is asked with an understanding that the complete package of aerodynamics and rolling resistance trump comfort or user-friendliness.
The person that does triathlon or tifes for fun, personal development, competition, and socialization? They want to go as fast as reasonably possible, but they have realistic constraints on their time and athletic auction bikes. Also, they want to be comfortable.
What should they choose? I asked for this information with the caveat that not all bike frames can fit wide tires, even today.
How far can we go before we turn our carbon race bikes into glorified Boris bikes? The key is striking a harmonious balance between rolling resistance and aerodynamics. The other factors — the reduced risk of pinch-flats and being able to lower tyre pressures for comfort 32 better handling — are a done deal. Home Platform bike rack comparison General News.
If wider tyres work for the pros, then they can work for us too. Nairo Quintana: Tyres suitable for use with dedicated tubeless rims, or with a conversion system which employs tape to seal the rim bed, are marked using a sidewall decal as tubeless-compatible, tubeless-ready, tubeless-easy or similar and have a special stretch-resistant folding bead made, usually, of carbon-fibre.
Road bike tires 23 vs 25 primarily for racing, tubular tyres must be fixed to an appropriate rim using glue, tirds or adhesive tape. These will all fit the same size rim. Tubular tyres require skilled fitting; if unsure, consult road bike tires 23 vs 25 suitably trained cycle hires. All tyres are marked with a pressure.
Sometimes this is an absolute maximum that nobody should need bike clip exceed, or sometimes only a recommended maximum that may be exceeded by heavier riders e. Off-road tyres are usually marked with a pressure range, from the minimum that will support a rider of average weight to the absolute maximum.
Do not exceed the maximum when tyres are marked with a range. Skip to main content. A guide to cycle tyre sizes.
Cycle tyre sizes explained. By Richard Hallett Thursday, 5 July Those gains are at the thinnest end of marginal. But a 25mm tyre does give you a greater volume of air so a little more comfort, though IME it's not 'night and day'.
Pressure can make quite a difference, mainly because too hard a tyre will be bouncing you and your bike around instead of deforming and absorbing surface irregularities. I'm 62 kg and for racing I put psi in my Ultremos bike bus smooth courses, 90 psi on the rougher ones.
I began racing club TTs on 28mm Bontrager Hardcase tyres talk about making it harder! If you were another 10 kg heavier I'd add 5 psi to those numbers but every rider should establish their preferred pressures. More road bike tires 23 vs 25 suggestions - http: Well yes, hence the term marginal! The OP wanted to know the difference between 23 and 25 mm tires. That's a question about marginal issues!
On another note, I must be a bit mad running my tubs at psi! Higher for TTs, but it works for me.
I have read that tubs roll well with higher pressures but I'd not want to race on Shropshire roads at that. A friend of mine is a bit lighter than me.
She uses Orad tubs on her Navigators and doesn't normally go over psi. These are small differences, that you would roqd notice road bike tires 23 vs 25 training where comfort is more important, but there is no way in hell I would use a 25 for a TT. Sorry, just saw this. The difference is certainly NOT marginal.
Gains on rolling resistance with 25mm tyres are certainly greater than 1W when tested on real roads, not steel drums.
The worse the road surface, the more significant gains largely thanks to lower pressure not width per se. That is interesting, I run 28s on my commuter bike and have found 80psi on davis bike club rear about right for the rear just by trial, error and feel raod which more or less tallies with the chart.
I tend to run the front higher than the 60 recommended there though, too many deep, sharp edged potholes to risk lower. Friends of mine have been carried into the air and come crashing down.
Whether riding a time trial or tearing down a gravel mountain road, there is no reason not to ride on wider tires. At the end of the day, the facts are the facts; a 25mm tire experiences less rolling resistance than a 23mm tire at the same air pressure. Without cutting too deep tirres the science of the matter, it all comes down to the contact road bike tires 23 vs 25.
As rires can see, less energy will be wasted on material deformation with a 25mm tire at equal pressure. Speed, comfort, and handling — not bad.
In the aforementioned interview, Vormwalde estimates that 25mm tires come road bike tires 23 vs 25 a 40gram average weight penalty per wheelset. The real question is where this negative trumps the positive of tores overall rolling resistance? People smarter than myself have said that only top-level sprinters and climbers have anything to fear in this department. Admittedly, I could be wrong.
