“The most comfortable ride was achieved with the 28mm tyres at a pressure of 5.5 bar: the tyre still having plenty of reserve suspension travel due to its copious volume, while at the same time being barely at risk of puncture,” it says.
Do pros ride 28mm tyres?
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 wider tyres more comfortable?
Both types have their benefits
The volume of air in a tire will particularly affect their driving comfort. The larger the rim diameter, the less air will fit in the tire. High-profile tires with plenty of space for air are more comfortable than wide, low-profile tires.
Which is faster 25c or 28c?
According to data from https://www.bicyclerollingresistance.com/specials/conti-gp4000s-ii-23-25-28 , 25c at 80 psi is slightly more efficient as compared to 28c at 60 psi and those pressures are in the ballpark area of what I would run typically.
Are 28mm tires slower?
‘Also a 28mm tubeless tyre is the fastest setup [in rolling resistance tests]. At 40kmh a high-quality clincher tyre with a latex inner tube is about 2 watts slower. And a 32mm tyre is only about 2 watts slower than an equivalent 28mm tyre.
Can I put 28mm tyres on my road bike?
Road bike-style commuting bikes might accept a tyre of around 28mm width, often with space for mudguards, but some commuting bikes, and those based on mountain bikes, will take up to a 44mm tyre.
What size tyres do Tour de France riders use?
As of Friday, four of the six road stages thus far in the 2017 Tour de France have been won on 26mm tubulars. While 23mm was the pro standard not so long ago, this year 20 teams are using 25mm tires for non-time trial stages, and the other two Specialized-sponsored teams are using 26mm rubber.
Does a wider tire give a smoother ride?
Avoid bigger wheels if you want a smoother ride.
As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car.
Do wider tires slow you down?
Slower Acceleration and Harder Steering
Wider tires are heavier, which, as a consequence, adds more weight to the car. This decreases the car’s acceleration. With its large contact area, wide tires not only slow down acceleration but also cause hard steering and poor car handling.
Can you put 28mm tyres on 23mm rims?
28mm tire on 23mm rim may suffer a bit more. Both aren’t 28mm tire on 28mm or wider rim anyway. Since you don’t bother matching tire width to rim width to begin with, just screw aero and ride what you feel good. No problems.
Is 28C enough for gravel?
If it is classic gravel road you might be in for a bumpy ride but it is doable. 28 would be the bare minimun I would want on dry hard packed gravel. In wet conditions I find tires that narrow cut a groove into the trail and are very difficult to keep rolling.
Which is better 700×28 or 700×25?
You will not notice the difference between 25 and 28. Tire pressure and tread pattern are far more significant in terms of rolling resistance, and the difference in diameter/gear ratio is too small for you to feel.
What size tyres do pro cyclists use?
In the past, road bikes used tyres as narrow as 18c, but over time racers have realised that a larger volume/width tyre offers better comfort, grip and even a lower rolling resistance. Whilst just a few years ago most professional cyclists were using 23mm, 25mm tyres are now the standard.
What PSI should 28mm tyres be?
For road, gravel, and MTB, your weight is more over the rear tire than the front. As such, you should use a higher rear tire pressure. I normally shoot for about a 2-3% difference (say, 73psi front, 75psi rear for 28mm tires). The thickness of your tire can affect the best pressure.
Are wider bike tires more stable?
Larger wheels make the bike more stable, and so do heavier wheels – because of the rotational inertia. Since wider tires are (slightly) heavier, you’ll want to decrease the wheel size to keep the rotational inertia – and thus the handling – the same.
What tyre width is fastest?
Or have they? Specialized has tacked on an extra millimetre and is making its super-quick Turbo S-Works and Turbo Cotton tyres in a 26mm width, and rolling resistance tests conducted on behalf of Velonews magazine found them to be the fastest-rolling tyres tested .
